,,book ,,company1 ,,inc4 ,,the ,,maple ,,press ,,york ,,pa ,,preface ,in preparing this manuscript the author has had in mind the needs of young men having no technical instruction who are anxious to become proficient in the art of ,plumbing4 ,as a consequence each exercise is minutely described and illustrated2 so much so1 perhaps1 that an experienced mechanic may find it too simple for skilled hands and a mature mind4 ,but the beginner will not find the exercises too elaborately described and will profit by careful study4 ,years of experience and observation have shown the author that the methods herein described are entirely practical and are in common use today4 ,the various exercises in lead work will acquaint the beginner with the correct use of tools and metals4 ,the exercises in iron pipe work have also been detailed to show the correct installation of jobs4 ,together with the study of this book the subjects of ,mathematics1 ,physics1 ,chemistry1 ,drawing and ,english should be taken4 ,these subjects as they bear on ,plumbing are invaluable to the mechanic in his future connection with the trade4 ,the author is indebted for the illustrations of fixtures in the chapter covering the development of plumbing fixtures1 to the ,thomas ,maddock's ,sons ,co41 ,standard ,sanitary ,mfg4 ,co41 and ,the ,trenton ,potteries ,co4 ,,samuel ,,edward ,,dibble4 ,,pittsburgh1

,i ,,plumbing ,,fixtures ,,and ,,trade ,modern plumbing as a trade is the arranging and running of pipes to supply pure water to buildings1 the erecting of fixtures for the use of this supply1 and the installing of other pipes for the resulting waste water4 ,the work of the trade divides itself therefore into two parts3 first the providing an adequate supply of water2 and second1 the disposing of this water after use4 ,the first division offers few problems to the plumber1 little variety in the layout being possible1 and the result depending mostly upon the arrangement of the pipes and fittings2 but the second division calls for careful study in the arrangement1 good workmanship in the installing1 and individual attention to each fixture4 ,the trade had its beginnings in merely supplying fresh water to a community4 ,this was done by means of trenching1 or conveying water from lakes1 rivers1 or springs through wooden pipes or open troughs4 ,by easy stages the trade improved and enlarged its scope1 until at the present time it is able to provide for the adequate distribution of tons of water under high pressure furnished by the city water works4 ,in the early years of the trade the question of the disposal of the waste water was easily answered1 for it was allowed to be discharged onto the ground to seek its own course4 ,but with the increased amount of water available1 the waste-water problem has enlarged until today it plays the most important part of plumbing1 and the trade has had to change to meet this waste-water problem4 ,the first simple system of a pipe running from the sink to a point outside the building was sufficient4 ,as larger buildings came into use and communities were more thickly populated1 the plumbing problem demanded thought and intense study4 ,the waste pipes from fixtures had to be so arranged that it would be impossible for foul odors and germ-laden air to enter the building through a plumbing fixture4 ,the importance of this is evidenced by the plumbing laws now in use throughout the country4 ,one of the first plumbing fixtures put into common use was a hollowed-out stone which served as a sink4 ,it was with considerable interest that the writer saw a sink of this kind in actual use in the summer of #aiae1 at a house in a ,new ,england village4 ,this sink had been in service for about #ajj years4 ,from this beginning the well-known fixtures of today have developed4 ,the demand for moderate priced1 sanitary closets1 lavatories1 and baths has led to the rapid improvement seen in plumbing fixtures4 ,in the development of these fixtures1 as soon as a bad feature was recognized the fixture was at once discarded1 until now the market offers fixtures as mechanically fine as can be produced4 ,plumbing fixtures were at first manufactured so that it was necessary to support them on a wooden frame1 and this frame was enclosed in wood4 ,the enclosure made by this framework soon became foul and filthy and a breeding place for all kinds of disease germs and vermin4 ,this bad feature was overcome by the introduction of open plumbing1 that is1 fixtures so made that the enclosure of wood could be done away with4 ,the open plumbing allowed a free circulation of air around the fixture and exposed pipes1 thereby making the outside of the fixture and its immediate surroundings free from all the bad features of the closed plumbing4 ,plenty of fresh air and plenty of light are necessary for good sanitary plumbing4 ,the materials of which the first open-plumbing fixtures were made consisted of marble1 copper1 zinc1 slate1 iron1 and clay4 ,time soon proved that marble and slate were absorbent1 copper and zinc soon leaked from wear1 iron rusted1 and clay cracked and lacked strength2 therefore these materials soon became insanitary1 and foul odors were easily detected rising from the fixture4 ,besides these materials being insanitary1 the fact that a fixture was constructed using a number of sections proved that joints and seams were insanitary features on a fixture4 ,for instance1 in a marble lavatory constructed by using one piece for the top1 another for the bowl1 and still another for the back1 filth accumulated at every joint and seam4 ,following this condition1 developed the iron enameled and earthenware fixtures1 constructed without seams and with a smooth1 even1 glossy white finish4 ,the fact that these fixtures are made of material that is non-absorbent adds to their value as sanitary plumbing fixtures4 ,illustration3 ,,fig4 #a4--,pan closet 7,english74 ,another problem which is as important as the foregoing is the proper flushing1 that is1 the supplying of sufficient water in a manner designed to cleanse the fixture properly4 ,the development of sanitary earthenware illustrates how the above problems were satisfactorily solved4 ,in the city of ,london a law compelling the use of drains was enforced1 and in the early #gj's the effect of this law was felt in this country4 ,the introduction at this time of the mechanical water closet1 known as the pan closet1 and the ,english plumbing material which was brought to this country was the beginning of ,american plumbing1 which today outstrips that of any other country in the world4 ,the pan closet continued in use for some time until the valve closet was introduced as a more sanitary fixture4 ,closely following these closets1 in #ahhj1 the plunger closet became popular as a still more sanitary fixture4 ,the plunger closet continued in use until the present all-earthenware closet bowl drove all other makes from the market4 ,the ,american development of the earthenware closet bowl put the ,american sanitary fixture far ahead of the ,english improvements1 as the ,american earthenware is superior and the sanitary features of the bowls are nearer perfection4 ,illustration3 ,,fig4 #b4--,pan closet 7,american74 ,illustration3 ,,fig4 #c4--,plunger closet4 ,when the washout bowl was introduced it was considered perfection4 ,the hopper closet bowl1 which was nothing more than a funnel-shaped bowl placed on top of a trap1 was placed in competition with the washout bowl4 ,there are a number of these bowls now in use and also being manufactured4 ,however1 large cities prohibit their use4 ,illustration3 ,,fig4 #d4--,plunger closet4 ,to quote ,thomas ,maddock's ,sons ,co43 ,in #ahgf ,wm4 ,smith of ,san ,francisco patented a water closet which employed a jet to assist in emptying the bowl and the development of this principle is due entirely to the potter1 who had gradually and by costly experiment become the determining factor in the evolution of the water closet4 ,with this improvement it became possible to do away with the boxing-in of the bowl which up to this time had been necessary4 ,closet bowls of today are made of vitreous body which does not permit crazing or discoloring of the ware4 ,a study of the illustrations which show the evolution of the closet bowl should be of interest to the student as well as to the apprentice and journeyman4 ,the bath tub developed from a gouged-out stone1 in which water could be stored and used for bathing purposes1 to our present-day enameled iron and earthenware tubs4 ,the development did not progress very rapidly until about #be years ago4 ,since then every feature of the tub has been improved1 and from a sanitary standpoint the tubs of today cannot be improved4 ,the bath tub has become an ,american custom1 as the people in this country have demanded that they have sanitary equipment in their homes1 while in the ,european countries this demand has not developed4 ,illustration3 ,,fig4 #e4--,modern low-tank closet4 ,the first tubs used in this country were of wood lined with copper or zinc1 and were built in or boxed in with wood panelling4 ,the plumbing ordinances of today prohibit this boxing as it proved to be a breeding place for vermin1 etc4 ,as the illustration shows1 the woodwork encasing the tub was in a great many cases beautifully carved and finished4 ,the placing on the market of a steel-clad tub1 a steel tub with a copper lining1 which did away with the boxing1 was a big improvement as far as sanitary reasons were concerned as well as a reduction in cost of tubs4 ,these tubs were set up on legs which permitted cleaning and provided good ventilation all around4 ,with these features they drove all other tubs from the market4 ,the copper and zinc were found to be hard to keep clean and they were soon replaced by the iron enamelled and earthenware tubs4 ,the finish on these tubs being white and non-absorbent makes them highly acceptable as sanitary fixtures4 ,a study of the illustrations will show how progress has been made in design as well as in sanitary features4 ,illustration3 ,,fig4 #f4--;,encased bath tub4 ,illustration3 ,,fig4 #g4--,steel tub on legs4 ,,the ,,wash ,,bowl4--,succeeding the hand basin the first wash basins used in this country were made of marble or slate1 with a round bowl of crockery4 ,the bowl was #ad inches in diameter originally1 but later was changed to an oval bowl4 ,like the bath tub these wash stands were encased in wood1 the encasing being used to support the marble top4 ,ornamental brackets were introduced and the wood encasement done away with4 ,illustration3 ,,fig4 #h4--,modern built-in tub4 ,illustration3 ,,fig4 #i4--;,encased wash bowl4 ,about #aijb the iron-enamelled lavatory appeared on the market and drove all other kinds from the market at once4 ,the reason for this is clear4 ,the marble stands were absorbent and were made with three parts1 top1 back1 and bowl2 the enamelled iron lavatory is made all in one piece of material non-absorbent4 ,a study of the illustrations will show clearly how the lavatory has been improved4 ,strange to say1 in all plumbing fixtures1 and especially the lavatory1 as improvements were made to make them more sanitary a reduction has been made in the price of an individual fixture4 ,illustration3 ,,fig4 #aj4 ,illustration3 ,,fig4 #aa4--;,bath room of early #hj's4 ,all fixtures are enclosed4 ,the development of the urinal1 showers1 wash trays1 drinking fountains and other fixtures ,i will not attempt to cover4 ,as the demand has been evident for fixtures of certain types1 the plumber has been alert to anticipate and supply it4 ,there is need1 however1 for improvement in all our fixtures1 especially that part which connects with the waste pipes1 also the hanging1 that is the arrangement or lack of arrangement for hanging fixtures to the wall4 ,the waste and overflow of all fixtures need considerable change to make them sanitary4 ,the opportunity is1 therefore1 before anyone who will apply himself to this development4 ,much money1 thought1 and time have been spent by the manufacturers of iron enamelled ware and by the potteries to gather suggestions made by the plumber in regard to fixtures1 and then to perfect them4 ,to these manufacturers is due the beautiful design1 stability1 and perfect sanitary material which make up our plumbing fixtures of today4 ,illustration3 ,,fig4 #ab4 ,,chapter ,,ii ,,the ,,use ,,and ,,care ,,of ,,the ,,soldering ,,iron4 ,,fluxes4 ,,making ,,different ,,soldering ,,joints ,illustration3 ,,fig4 #ac4--;,copper4 ,,the ,,soldering ,,iron4--,the soldering iron is one of the first tools a plumber has to master4 ,this tool is sometimes called a copper bit as it is made of copper2 and so throughout this book the words soldering iron1 copper bit1 iron1 and bit are used synonymously4 ,there are several different-shaped irons in common use today1 but an iron shaped like the one in ,fig4 #ac is the one for use in the following work4 ,take the iron as it is purchased1 having a wooden handle and the copper exposed on pointed end4 ,before it can be used the point must be faced and tinned4 ,to do this1 proceed as follows3 ,first1 heat the iron on the furnace4 ,second1 place in vise and file the four surfaces of the point4 ,third1 run a file over edges and point4 ,fourth1 heat the iron until it will melt solder4 ,fifth1 put #f or #h drops of solder and a piece of rosin the size of a chestnut on an ordinary red brick4 7,this rosin is called a flux47 ,sixth1 take the hot iron and melt the solder and rosin on the brick4 ,seventh1 rub the four surfaces of the point of the iron on the brick keeping the point in the melted solder4 ,the solder will soon stick to the copper surfaces and then the iron is ready for use4 ,another way to tin the iron that is in common use is to rub the point of a hot iron on a piece of sal-ammoniac1 or dip the hot iron in reduced muriatic acid1 then rub the stick of solder on the iron4 ,the use of muriatic acid in tinning the iron is not recommended4 ,in the first place1 it is not always possible to carry it1 and in the second place it eats holes in the surface of iron1 which makes it necessary to file and smooth the surfaces again4 ,the constant use of muriatic acid on the copper soon wears it away and makes it unfit for use4 ,rosin is easily carried and applied and is by far the best to use in regular work4 ,,points ,,to ,,remember ,,in ,,the ,,care ,,of ,,the ,,soldering ,,iron4-- ,first1 proper tinning is absolutely necessary for rapid and good work4 ,second1 do not allow the iron to heat red hot4 ,third1 keep the point of the iron properly shaped4 ,fourth1 use the same flux in tinning as is to be used in soldering4 ,fifth1 when filing iron1 file as little as possible4 ,sixth1 keep in use two irons of the same size4 ,,flux ,a flux is used to clean the surfaces of joints and seams to be soldered1 also to keep them from oxidizing and to help the metals to fuse4 ,the following list gives the names of various fluxes in common use1 how they are applied1 and on what material they are most commonly used3 ,flux ,how applied ,used on ,rosin ,sprinkled on ,lead1 tin1 and brass ,tallow ,melted ,lead and brass ,muriatic acid 7reduced7 ,with swab ,copper1 galvanized iron and brass ,muriatic acid 7raw7 ,with swab ,dirty galvanized iron ,,rosin4--,rosin is purchased by the pound and comes in chunks4 ,it is very brittle and powders easily4 ,plumbers generally take a piece of #a-a_/d ,n4 ,p4 brass tubing1 solder a trap screw in one end and a cone-shaped piece of copper on the other4 ,the point of the cone is left open4 ,rosin is put into this tube and is easily sprinkled on work when needed4 ,,tallow4--,a plumber's tallow candle answers the purpose for tallow flux4 ,some plumbers carry a can for the tallow1 making it cleaner to handle4 ,,muriatic ,,acid4--,muriatic acid or hydrochloric acid is used both raw and reduced4 ,raw acid is not diluted or reduced4 ,reduced acid is made as follows3 ,put some zinc chips in a lead receptacle and then pour in the muriatic acid4 ,the acid will at once act on the zinc4 ,the fumes should be allowed to escape into the outer air4 ,when chemical action ceases1 the liquid remaining is called reduced acid4 ,,plumbers' ,,soils ,,and ,,paste ,it is necessary when soldering or wiping a joint to cover the parts of pipe adjoining the portion that is to be soldered or wiped so that the solder will not stick to it4 ,there are a number of preparations for this4 ,the one used by the best mechanics today is paste1 made as follows3 #h teaspoons of flour4 #a teaspoon of salt4 #a teaspoon of sugar4 ,mix with water and boil down to a thick paste4 ,the advantages of paste as a soil are many3 ,first1 it is made of materials easily obtained4 ,second1 solder will not stick to it4 ,third1 if pipe is thoroughly cleaned1 the paste will not rub off easily4 ,fourth1 poor workmanship cannot be covered up4 ,fifth1 when the work is completed1 a wet cloth will wipe it off and leave the work clean4 ,another soil used is lampblack and glue4 ,a quantity of glue is melted and then lampblack is added4 ,this needs to be heated and water added each time it is used4 ,this soil is put on pipes with a short stubby brush4 ,the work when completed with the silvery joint and jet black borders appears to the uninitiated very artistic and neat1 but when the black soil is worn away the uneven edges of the joint appear1 disclosing the reason for using a black soil that covers all defects4 ,the mechanic of today who takes pride in his ability for good workmanship will not cover his work with black soil4 ,it can readily be seen that the use of lampblack soil encourages poor workmanship1 while the use of paste forces1 to a certain extent1 good workmanship on the part of the mechanic4 ,before soil or paste is applied1 the pipe needs to be cleansed4 ,grease and dirt accumulate on the pipe4 ,the methods employed to remove all foreign matter are simply to scrape the surface with fine sand or emery paper2 sand and water will also answer for this purpose4 ,this cleans the surface and allows the soil or paste to stick to the pipe4 ,,making ,,different ,,solder ,,joints ,the tools used in making the different solder joints as described and illustrated in this chapter are shown in ,fig4 #ad4 ,,cup ,,joint4--,the materials necessary for the work 7,fig4 #ae73 #ab inches of #a_/b-;inch ,,aa lead pipe1 paste1 rosin1 #a_/b and #a_/b solder4 ,if a gas furnace is not on the bench to heat the iron1 then a gasoline furnace is necessary4 ,each of the following operations must be done thoroughly to insure a perfect job3 ,first1 with the ,,saw cut off #ab inches of #a_/b-;inch ,,aa lead pipe from the coil4 ,when cutting off a piece of lead pipe from a coil or reel1 always straighten out #a foot more than is needed4 ,this leaves #a foot of straight pipe always on the coil4 ,illustration3 ,,fig4 #ad4--,tools used for making solder joints4 ,second1 with the flat side of the ,,rasp1 square the ends of the #ab-;inch piece of pipe4 7,a good way to do this is to hold the pipe at right angles with the edge of the bench1 run the rasp across the end of the pipe1 keeping the rasp parallel with the edge of the bench4 ,apply this to all work when necessary to square the ends of pipe47 ,third1 cut the pipe with the saw1 making two pieces each #f inches in length4 ,fourth1 square the ends just cut4 ,fifth1 rasp the edges of one end as shown in the cut4 ,hold the work in such a way that the stroke of the rasp can be seen without moving the pipe4 ,sixth1 take the other #f-;inch piece of pipe and with the ,,turn ,,pin spread one end of it4 ,the turn pin must be struck squarely in the center with the ,,hammer1 the point of the turn pin being kept in the center of the pipe4 ,the pipe should be turned after each blow of the hammer4 ,the pipe must not rest on the bench but should be held in the hand while using the turn pin4 ,if the pipe bends1 it can be straightened with ,,bending ,,irons4 ,if the pipe is spread more on one side than the other1 the turn pin should be hit on the opposite side so as to even the spread4 ,illustration3 ,,fig4 #ae4 ,seventh1 when the pipes are properly fitted1 moisten the tips of the fingers with paste and rub the paste on parts of pipe marked paste4 ,put the pipe aside to allow the paste to dry4 ,eighth1 put the soldering iron on to heat4 ,ninth1 with the ,,shave ,,hook scrape off the paste and surface dirt as shown in the figure4 ,the inside of the cup will look bright1 but must be scraped4 ,illustration3 ,,fig4 #af4--;,cup joint4 ,tenth1 place the two pieces into position as shown in ,fig4 #af1 sprinkle rosin on the joint1 melt a few drops of solder on the joint and with the iron melt the solder on the joint1 drawing the iron around the pipe keeping the solder melted around the iron all the time4 ,eleventh1 fill the joint with solder and continue to draw the hot iron around the joint until a smooth and bright surface is obtained4 ,to master the correct use of the soldering iron in this work1 considerable practice will be necessary4 ,,overcast ,,joints4--7,fig4 #ag47 ,,note4--,each operation must be performed thoroughly4 ,first1 saw off from a coil of #a-a_/b-;inch ,d lead pipe a #aj-;inch piece of pipe4 ,second1 square the ends with the rasp1 as previously explained4 ,third1 take a #a-a_/b-;inch ,,drift ,,plug and drive through the pipe 7,fig4 #ah74 ,fourth1 saw the pipe into two pieces of #e inches each4 ,fifth1 square the ends of the pipe with the rasp4 ,sixth1 rasp off the outside edge of one end of the pipe as shown4 ,seventh1 rasp off the inside edge of one end of the pipe4 ,eighth1 finish rasped surfaces with a file4 ,both surfaces should have the same angle4 ,illustration3 ,,fig4 #ag4 ,illustration3 ,,fig4 #ah4 ,illustration3 ,,fig4 #ai4--,overcast joint4 ,ninth1 with a shave hook scrape the outside surface of each pipe for about #a inch from the end4 ,tenth1 put the soldering iron on to heat4 ,eleventh1 paste paper on the joint as shown in the cut4 ,twelfth1 fit the pieces together and lay on the bench4 ,drop some melted solder on the joint and with the hot iron proceed to flow the solder around the joint by turning the pipe4 ,use plenty of flux 7rosin74 ,the pipes must be tacked in three or four places at first or they will have a tendency to spread4 ,thirteenth1 to finish the joint1 lift the iron straight up4 ,this joint when finished will have a bright smooth finish4 ,the two foregoing joints need considerable practice and should be perfectly mastered before going on to the next job4 ,,seams ,a description of the making of wiped seams for lead-lined tanks will not be attempted as very few are made now4 ,the plumber1 however1 is often called upon to make a seam joining two pieces of sheet lead4 ,the beginner will do well to go over the following exercise carefully and practice it thoroughly4 ,illustration3 ,,fig4 #bj4--;,flat seam4 ,,materials4--,two pieces of #h-pound sheet lead1 #f by #aj inches each2 one bar of #a_/b and #a_/b solder2 paste1 paper1 and rosin4 ,,tools4--,rasp1 shave hook1 and soldering iron4 ,the #aj-;inch side of each piece is rasped and fitted together4 ,the edges are cleaned and paper is pasted on leaving #a_/d inch for solder4 ,paste without the paper can be put on4 ,this will make a joint #a_/b inch wide4 ,apply the rosin to the joint1 then with the heated iron and some solder tack the seam on the top1 then on the bottom and middle4 ,this will prevent the seam from spreading when the lead is heated4 ,solder and rosin can now be put on the full length of the joint4 ,with a hot iron proceed to float the solder down the seam4 ,the soldering iron must not rest at full length on the pieces of lead or it will melt the lead and render the work useless4 ,the solder will flow and form a clean neat seam1 if the iron is at the right heat and the right amount of solder is put on4 ,if the iron is too hot1 the solder will flow instantly when the iron is laid on it and the solder will disappear as it runs through the seam4 ,if the iron is too cold the solder will not melt enough to flow4 ,too much solder on the seam will cause it to overflow1 that is1 the solder will spread beyond the papered edges4 ,after a little practice this surplus solder can be drawn in on the seam with the iron and carried along the seam to some point that has not enough solder4 ,when the seam is completed the edges should be perfectly straight and even4 ,the iron is carried along the seam with one stroke which makes the seam appear smooth and bright4 ,,chapter ,,iii ,,mixtures ,,of ,,solders ,,for ,,soldering ,,iron ,,and ,,wiping4 ,,care ,,of ,,solders4 ,,melting ,,points ,,of ,,metals ,,and ,,alloys ,the importance of good solder1 that is1 solder correctly mixed and thoroughly cleaned1 should not be overlooked4 ,work is more quickly and neatly done and the job presents a more finished appearance when solder that is correctly made is used4 ,the solder used in the following work with the soldering iron is called #a_/b and #a_/b4 ,this means #a_/b 7#ej per cent47 lead and #a_/b 7#ej per cent47 tin4 ,in the mixture of solder1 only pure metals should be used4 ,the lead should be melted first and all the dross cleaned off4 ,the tin should then be added and mixed4 ,the solder to be used in wiping the joints in the following chapter is a mixture of #cg per cent4 tin and #fc per cent4 lead4 ,this is called wiping solder4 ,the following table gives the melting points1 etc43 ---------------------------------------- -------------------------- ,melting ,metal point ,mixture ---------------------------------------- -------------------------- ,sulphur #bbh ,pure ,tin #ddf ,pure ,lead #fbf ,pure ,zinc #fhj ,pure ,fine solder #djj #ej per cent4 tin1 #ej per cent4 lead 7wt47 ,wiping solder #cgj #cg per cent4 tin1 #fc per cent4 lead 7wt47 ---------------------------------------- -------------------------- ,to recognize fine solder1 run off a bar into a mold and let it cool4 ,if there is a frosted streak in the center1 the metal has not enough tin4 ,the surface should be bright4 ,to recognize wiping solder1 pour some on a brick4 ,when this is cool1 the top should be frosty and the under side should have four or five bright spots4 ,the amount poured on the brick should be about the size of a half dollar4 ,if poured on iron1 the metal will cool too quickly and show bright all over the under side4 ,,to ,,make #a_/b ,,and #a_/b ,,solder ,,or ,,plumber',s ,,fine ,,solder4--,the possibility of getting pure clean metals to mix solder is very remote4 ,old pieces of lead pipe1 lead trap1 old block tin pipe are used to make solder when pure metals are not at hand4 ,first1 in a cast-iron pot melt the lead to about #hjj deg41 or a dull red4 ,second1 clean off the dross4 ,third1 add 7to a #ae-pound pot7 #a_/b pound of sulphur in three applications4 ,each time mix the sulphur thoroughly with the metal with a long stick4 ,fourth1 add tin before the last application of sulphur4 ,mix thoroughly4 ,fifth1 pour off two bars and look for the frosty streak in the center4 ,add a little more tin1 if necessary4 ,,to ,,mix ,,wiping ,,solder4-- ,first1 proceed as described in #a_/b and #a_/b1 melting the metals and burning out with sulphur1 adding the percentage of tin according to the preceding table4 ,then test the solder for bright spots on the under side4 ,second1 keep the metal thoroughly mixed when burning and keep all dross cleaned off the surface4 ,the working heat of wiping solder is #ejj deg4,f4 ,sulphur is used to collect all zinc and dross4 ,the sulphur should come in contact with all parts of the metal4 ,this is why the metal should be stirred when the sulphur is put in4 ,a few good points in the economical care of solder are listed below4 ,,care ,,of #a_/b ,,and #a_/b ,,solder4-- ,first1 do not drop melted solder on the floor or dirty bench4 ,second1 use all small ends by melting on a new bar4 ,third1 put clean paper under work and use droppings4 ,fourth1 have the mold free from dirt when pouring4 ,,care ,,of ,,wiping ,,solder4-- ,first1 do not heat red hot4 ,second1 do not file brass where the filings will get into the solder4 ,third1 do not allow lead chips to get into the solder4 ,fourth1 clean the solder occasionally4 ,fifth1 learn to distinguish solder from lead by its hardness4 ,sixth1 have different-shaped pot for lead and solder4 ,seventh1 do not tin brass by dipping into solder4 ,eighth1 do not put cold or wet ladle into hot solder4 ,a pot holding about #ae pounds of solder is the size commonly in use4 ,,chapter ,,iv ,,making ,,and ,,care ,,of ,,wiping ,,cloths ,a good wiping cloth is essential for wiping joints4 ,the exact size and the flexibility of the cloth depend a great deal upon the mechanic who handles the cloth4 ,some mechanics like a stiff cloth1 but the writer has always used a flexible cloth4 ,the sizes1 shape1 and methods of folding and breaking in as shown in ,fig4 #ba below have proved successful4 ,cloths made of whalebone ticking are inexpensive and make the best for ordinary use4 ,illustration3 ,,fig4 #ba4--;,folding a wiping cloth4 ,size of cloth open ,size of cloth folded #ad-a_/b by #ad-a_/b inches equals #c-a_/d by #c-a_/d inches #ac-a_/b by #ac-a_/b inches equals #c by #c inches #h-a_/b by #ab-a_/b inches equals #b by #c inches ,for the joint-wiping jobs to follow1 the above sizes are the best4 ,the largest size1 #ad-a_/b by #ad-a_/b inches is used for catch cloth4 ,the #ac-a_/b by #ac-a_/b inches is the wiping cloth4 ,the #h-a_/b by #ab-a_/b inches is the branch cloth4 ,proceed as follows to cut and complete a cloth3 ,first1 lay the ticking on the flat bench and square the sides #ad-a_/b by #ad-a_/b inches4 ,second1 the ticking should be cut off with shears and not torn or cut with a knife4 ,third1 fold as shown in the cut4 ,each fold should be moistened with a little water and pressed with a hot iron4 ,the cloth should not be pulled or stretched1 but should be kept as square as possible4 ,the first and second folds require a little care2 the corners when folded to the center should be kept in a little1 thus making the outside edge slightly rounded4 ,if this is done1 the corners will not stick out when the cloth is finished4 ,after the cloth is carefully folded1 pressed1 and dried1 take a needle and thread and sew the open corners about #a_/b inch in from the edge of the cloth4 ,by carefully studying the cut1 one can readily see each operation and1 by following directions1 make a perfect cloth4 ,when the cloth is done1 an amount of oil sufficient to soak through about three layers of cloth should be applied and then rubbed on a smooth surface4 ,the oil should be rubbed in well about the edges4 ,it will not be necessary to apply anything else to the cloth to prepare it for wiping4 ,paste1 soil1 chalk1 etc41 are not needed and do not benefit the cloth4 ,when using oil on the cloth1 it must not be used too freely1 that is1 the cloth must not be soaked in oil1 as oil is a rapid conductor of heat and the cloth would soon become too hot to handle4 ,,care ,,of ,,wiping ,,cloths4--,the ticking will burn if allowed to become too hot4 ,if hot solder is poured directly on the cloth1 it will soon burn and be destroyed4 ,keep the surface on both sides of the cloth well oiled4 ,use both sides of the cloth4 ,use both wiping edges of the cloth4 ,illustration3 ,,fig4 #bb4--,wiping cloth folded has #af thicknesses of ticking4 ,when the cloth is not in use1 it should not be thrown in with the other tools and allowed to curl up into all sorts of shapes1 but should be kept in some flat place4 ,a good way to keep the cloths is to have two pieces of wood between which the cloths may be kept and held there by means of a strap4 ,the length of time which a wiping cloth can be used depends a great deal upon its making and upon the care which is given it4 ,,chapter ,v ,,preparing ,,and ,,wiping ,,joints ,when the writer first started to carry the tools for a plumber and to prepare joints for wiping1 the remark was often heard that joint wiping would soon be a thing of the past4 ,i have heard this many times since from many different sources4 ,personally1 ,i fail to see the passing of the wiped joint4 ,more lead pipe is being made today than ever before1 which goes to show that lead pipe is being used and the only successful way of joining is with the wiped joint4 ,some plumbers' helpers of today seem to think that joint wiping is of no account4 ,to a certain extent1 ,i can sympathize with them4 ,most of these boys are learning a trade in large cities and working for concerns that do nothing but a large contracting business4 ,this large work is carried on differently from the small work4 ,wrought-iron or steel pipes are used to a great extent in this work and a very small amount of lead is used4 ,sometimes the job will be completed without the use of lead4 ,the boy who works continually on this kind of work soon comes to think that lead pipes are no longer in use4 ,the writer has found that a boy who has learned to do nothing but screw-pipe work is absolutely lost and cannot perform the duties of a plumber1 other than screw-pipe work4 ,it must be borne in mind that lead pipe and cast-iron pipe work are being used today in all parts of the country and in some parts more than in others4 ,therefore1 the boy must grasp all branches of the trade that he has chosen to follow and not be a one-sided man4 ,joint wiping belongs to the plumber alone4 ,the plumbing trade differs from all other trades in that it has joint wiping for its distinctive feature4 ,a few attempts at joint wiping will convince the beginner that it is not the easiest thing in the world to learn4 ,let me caution the beginner not to get discouraged4 ,he must have patience and a firm resolve to master the art of joint wiping and not let it master him and keep him back4 ,so1 as we now start on exercises of joint wiping1 let the beginner constantly keep in mind that all boys must become perfectly skilled in the art of joint wiping before they can be considered plumbers4 ,keep in mind also that the examination that one must take to get a plumber's license contains an actual exercise in joint wiping4 ,the one word of advice is not to get discouraged4 ,continued practice is the only way to success4 ,the soldering iron is1 or should be1 conquered by this time4 ,as joint wiping is the next exercise1 ,i shall go over a few general points that experience has taught me and cannot fail to be of assistance to the beginner if they are heeded4 ,in fact1 to become proficient1 the beginner should remember all the points suggested under this heading4 ,it is necessary in wiping to have good solder4 ,in the chapter on solder1 ,i have given the correct mixtures and how to recognize the proper mixtures4 ,the place where wiping is to be done should be considered4 ,no draught should be allowed to blow across the work as it tends to chill the solder and pipe4 ,proper support for the work should be procured4 ,if gasoline is to be used for fuel to heat the solder1 make sure that the tank is full before starting1 otherwise the fire may go out just when the heat is needed most and the solder in the pot has become too cool to wipe with4 ,have a catch pan and keep all the solder droppings to put back into the pot1 otherwise the solder will pile up and the fingers are likely to be pushed into the pile and badly burned4 ,hold the ladle about #b inches above the work1 the catch cloth about #a inches below4 ,do not drop the solder in the same place4 ,keep moving the ladle4 ,do not pour the solder on the pipe in a steady stream1 but drop it on4 ,it is not a large amount of solder that is wanted on the joint at first1 it is heat that is needed4 ,this can be secured better by dropping the solder on than by pouring a large quantity on the pipe4 ,the edges of the joint cool very quickly2 therefore heat the edges well and keep them covered with molten solder until the joint is ready to wipe4 ,when preparing joints for wiping1 always do the work thoroughly and fit the pieces together tightly so that no solder can get through4 ,,points ,,to ,,remember4-- ,first1 good solder4 ,second1 place of wiping4 ,third1 support4 ,fourth1 full tank of gasoline4 ,fifth1 drip pan4 ,sixth1 ladle #b inches above the work4 ,seventh1 cloth #a inches below the work4 ,eighth1 move the ladle continually4 ,ninth1 drop the solder4 ,tenth1 heat1 not solder wanted at first4 ,eleventh1 heat the edges4 ,twelfth1 careful preparation4 ,thirteenth1 clean grease from the pipe4 ,fourteenth1 cut clean straight edges on paper4 ,,half-,,inch ,,round ,,wiped ,,joint ,,preparation4--,take #ab inches of #a_/b-;inch strong lead pipe and square off the ends with a rasp4 ,take the shave hook and scrape the center of the pipe perfectly bright2 a space #c inches each side of the center is correct4 ,the size of the joint when completed should be #b-a_/b inches long4 ,if we should undertake to wipe the joint with the pipe in the present condition1 the solder would adhere to all the pipe that was shaved bright4 ,therefore1 we take a piece of paper sufficient to encircle the pipe twice and after putting paste on one side of the paper wrap it around the pipe so that the edge that is cut straight and even is #a-a_/d inches from the center of the pipe4 ,another piece of paper is pasted on the other side of the center leaving a clean1 bright space of #b-a_/b inches4 ,all the pipe should be covered with paper except the #b-a_/b inches in the center4 ,illustration3 ,,fig4 #bc4 ,,to ,,put ,,the ,,pipe ,,in ,,position ,,for ,,wiping4--,the most practical way is to take two common red bricks with the #b by #h face down and place them #i inches apart4 ,lay the pipe on the bricks and place a weight on each end4 ,the solder will drop on to the bench1 so it is best to place a piece of paper or a pan of black iron under the pipe to catch the solder that drops4 ,the pan or paper can then be taken up and the solder put back into the pot without waste4 ,a cast-iron pot holding #ae pounds of solder is then placed on the furnace4 ,when the solder has melted and has reached #ejj deg4 it is ready for use4 ,this can best be determined by putting a piece of paper in the solder4 ,if the paper scorches1 the solder is at the right heat2 if the paper catches fire1 it is too hot4 ,now take a #c-;inch ladle and heat it over the fire and then dip it into the solder and skim off any dross that may have collected4 ,,wiping4--,with the ladle full of solder in the right hand and the large cloth or the catch cloth in the left hand1 begin to drop the solder on the joint4 ,the cloth should catch all the solder as it falls off the pipe4 ,if hot solder is held against the bottom of the pipe1 it is heated to the proper heat4 ,always begin to drop the solder on the paper edges1 then drop the solder on the joint itself4 ,bear in mind that the solder should not be poured on1 but dropped on slowly4 ,after the first few drops do not drop the solder directly on to the lead pipe but on to the solder previously put on the pipe4 ,this will save the pipe from burning through4 ,the pipe must be the same heat as the solder before the proper heat is obtained for good wiping4 ,the beginner should practice dropping the solder on the joint1 catching the solder and working it around the pipe4 ,by doing this1 one becomes familiar with the feeling of hot solder1 which is the secret of successful wiping4 ,when the solder works easily around the pipe1 drop the ladle and take the smaller wiping cloth in the right hand and with both cloths draw all the solder on top of the pipe4 ,with fingers on the corners of both cloths1 clean off the left-hand edge and with the right hand draw the surplus solder across to the right-hand edge4 ,next1 clean the right-hand edge of the joint pushing the surplus solder onto the cloth in the right hand4 ,work this solder on to the bottom of the joint4 ,now discard the catch cloth4 ,holding the wiping cloth with the index fingers on lower opposite corners1 shape the under and front side of the joint4 ,with the middle fingers on opposite lower corners of the cloth shape the back and top4 ,keep the index and middle fingers on the edge of the cloth and the edge of the cloth on the edge of the joint4 ,this position together with the size and shape of the cloth will give the joint the desired form and appearance4 ,particular attention is called to the position of the fingers as shown in the figure4 ,the last wipe should be a quick stroke coming off of joint on a tangent4 ,if the solder is at right heat1 the cloth will not leave a noticeable mark4 ,if1 however1 the solder is too cold1 a ragged edge will result4 ,sometimes a cross wipe is made for the last stroke and a good finish obtained4 ,,points ,,to ,,remember4-- ,first1 width of the joint1 #b-a_/b inches4 ,second1 allow no soil or paste to get on the joint4 ,third1 a #c-;inch ladle should be used4 ,fourth1 #ejj deg4 is the working heat of solder4 ,fifth1 paper test for solder heat4 ,sixth1 position of wiping cloths4 ,seventh1 do not drop solder on the lead pipe4 ,eighth1 hold the ladle #b inches above the pipe4 ,ninth1 wipe the edges of the joint first4 ,tenth1 wipe and shape the joint quickly4 ,the above procedure of wiping will be found to work out very easily if followed closely4 ,do not pour the hot solder onto the cloth as the cloth will burn through and soon be useless4 ,a little more oil should be put on the cloth after using it for awhile4 ,the cloth should be turned around and the opposite side also used4 ,the cloth will last considerably longer if sides are changed frequently4 ,the solder should not accumulate on the pan1 but should be continually put back into the pot4 ,the metal1 as solder is sometimes called1 should never be allowed to become red hot4 ,the above method of preparing pipe is suggested for beginners only and will be found to be a great help to them4 ,in actual practice the joint must be prepared differently4 ,the method used in trade is as follows3 ,the joint is used to join two pieces of lead pipe4 ,take two pieces and rasp the four ends square4 ,with the tap borer clean out the end of one pipe a trifle1 then with the turn pin enlarge this end just a little as shown in the figure4 ,then rasp the edge off about #a_/h inch as shown4 ,take the other piece of pipe and rasp one end as was done in the cup joint1 making it fit into the first piece4 ,then place the two ends together and with the bending iron beat the pipe1 making the joint as tight as possible4 ,,round ,,joint--#de deg4 ,,to ,,right ,the next position in which the beginner is to wipe a joint is on an angle of #de deg4 to the right4 ,,preparation4--,to prepare this joint1 proceed as in the horizontal round joint4 ,i will enumerate a few of these points4 ,a piece #ab inches long of #a_/b-;inch pipe is cut off and the ends squared4 ,a strip in the center1 #f inches long1 is shaved clean4 ,paper and paste are put over the pipe except #b-a_/b inches in the center4 ,grease can be put on the pipe in between the pieces of paper and will keep the lead from oxidizing4 ,,placing ,,pipe ,,in ,,position4--,there is no need of an elaborate system of holding the pipe in position4 ,take a red brick and place the #d by #h face down4 ,this will do for the bottom pipe4 ,for the top of pipe to rest on1 place two bricks one above the other2 this will give the correct position4 ,place the pipe on the brick and with a ladle full of half molten solder pour a clamp of solder over the end of the pipe4 ,this will hold the pipe firm for wiping4 ,place a catch pan under the joint for solder to fall in4 ,,wiping4--,the method of wiping this joint is practically the same as wiping the horizontal joint4 ,the catch cloth should be held parallel with the bench tilting a little from front toward the back4 ,the ladle is held the same and solder is dropped on as before4 ,the ladle should be continually moving while dropping solder1 not allowing the solder to drop twice in the same place4 ,when the solder has been worked around the pipe and is at working heat1 the solder is drawn up with both cloths and the top edge wiped first1 then the bottom edge2 the surplus solder is put on the underside of the joint1 and then with three or four wipes the joint is made symmetrical and finished4 ,,things ,,to ,,remember4-- ,first1 prepare like the horizontal joint4 ,second1 use brick to place in position4 ,third1 hold tools as in horizontal joint4 ,fourth1 top edge cools first1 therefore1 wipe it first4 ,fifth1 hold the wiping cloth at an angle of #de deg4 when wiping1 with fingers placed as noted in previous joint4 ,sixth1 make solder clamp for holding the pipe4 ,,round ,,joint #de deg4--,,left ,when the preceding joint is well mastered and a number of good joints have been wiped1 turn the pipe on an angle of #de deg4 to the left4 ,,preparation4--,the preparation for this joint is exactly the same as for the horizontal joint4 ,the beginner should turn back and read carefully concerning the perfection of the joint4 ,bear in mind that the pipe must be correctly prepared or a good joint cannot be made4 ,the edge of the paper must be cut not torn4 ,,placing ,,pipe ,,in ,,position4--,this pipe can be placed in position the same as the preceding one4 ,if heavy weights are placed on the ends of the pipe1 a bad habit may be formed by the one learning to wipe4 ,that is1 the habit of pressing hard on the joint when wiping4 ,in the preceding joint1 if the beginner presses too hard1 the pipe will fall off the bricks4 ,,wiping4--,proceed as described for previous joints4 ,the top edge must be favored a little4 ,the hot solder will run down to the bottom edge2 therefore less solder should be dropped on it than on the top edge4 ,when the solder is at the proper heat for wiping it requires only a light touch to wipe the joint4 ,if it appears necessary to press hard on the joint to wipe off surplus solder1 it shows that the solder is not at the correct wiping heat4 ,,round ,,joint--,,vertical ,,preparation4--,this joint can be prepared exactly like the preceding one4 ,in fact1 the same piece of pipe can be used throughout4 ,when preparing this joint the end that is to be on the bottom should be well covered with paper4 ,,placing ,,in ,,position4--,the best way to hold this joint in position for wiping is to stand the pipe upright on one end with the pan underneath4 ,a piece of furring strip should be run from the top of the pipe to the wall4 ,secure the strip to the wall and drive a nail through the strip into the bore of the pipe4 ,place a weight on top of the strip and the pipe is ready4 ,,wiping4--,the procedure of wiping this joint is entirely different from that in the other positions4 ,the solder is thrown onto the joint from the ladle4 ,the catch cloth is held up to the pipe and as much solder as possible is held on to the pipe4 ,move the ladle around the joint1 throwing a little solder on as the ladle is moved4 ,notice now that all the solder runs to the bottom edge1 leaving the top edge cold4 ,the solder that accumulates on the bottom edge should be drawn up to the top edge with the cloth4 ,then splash more solder on to the top edge and as the solder runs down the pipe catch it with the cloth and draw it up again4 ,the solder can be worked around and up and down the joint1 but always keep the top edge covered with hot solder4 ,the solder is likely to drop off the joint entirely unless watched closely4 ,when the correct heat is obtained1 drop the ladle4 ,take the wiping cloth in the right hand and with the fingers spread1 clean off the top edge quickly1 then shape the joint with the one cloth4 ,with a little practice you will gain this knack4 ,the joint can then be wiped4 ,the left hand can steady the pipe4 ,spread the index finger and third finger to opposite sides of the cloth and wipe around the joint4 ,,chapter ,,vi ,,preparing ,,and ,,wiping ,,joints 7,continued7 ,,two-,,inch ,,brass ,,ferrule ,,materials4--,the beginner should continue wiping the vertical round joint until he is able to obtain a symmetrical bulb4 ,a joint should be wiped in each of the foregoing positions for exhibition purposes1 so that the beginner can have before him the best work and strive to make the next joint better4 ,this next joint1 the #b-;inch brass ferrule1 is wiped in an upright position4 ,the materials necessary are the #b-;inch brass ferrule1 #f inches of #b-;inch light lead pipe1 paste and paper1 #a_/b and #a_/b solder1 rosin1 wiping solder1 catch pan1 and supports4 ,illustration3 ,,fig4 #bd4 ,,tools ,,required4--,the tools necessary for this work are as follows3 the saw1 rasp1 drift plug1 dresser1 file1 soldering iron1 bending irons1 wiping cloths1 shave hook1 and ladle4 ,,preparation4--,the lead pipe must be fitted into the brass ferrule4 ,the brass ferrule has to be tinned first4 ,to do this1 proceed as follows3 file the ferrule for about #b inches on the tapered end4 ,do not file too deep1 but just enough to expose the pure bright metal4 ,now measure from the small end #a-a_/d inches down toward the beaded end4 ,from this point to the bead1 cover the brass with paste and paper4 ,no paste must get on the #a-a_/d-;in4 filed end4 ,this end should not be touched with the fingers4 ,if paste gets on it1 the process of filing must be done over again as the solder will not stick where there is paste4 ,if the brass ferrule is filed while the paper is on the brass1 the filing will destroy the straight edge of the paper and an even joint cannot be made4 ,it would therefore be necessary to re-paper the brass4 ,take some powdered rosin and cover the filed end of the ferrule with molten solder using the rosin as a flux4 ,do not dip the end of the ferrule into the hot wiping solder to tin it or pour wiping solder on the brass ferrule4 ,this method of tinning the ferrule will spoil the wiping solder4 ,always use the soldering iron to tin the ferrule as explained above4 ,a little practice will develop the use of the iron in the hands of the beginner so that this tinning process will be done very rapidly4 ,the iron should be put on to heat when the paper is being pasted on the brass2 the iron will then be ready for use when needed4 ,,preparing ,,the ,,lead4--,the ends of the lead pipe must be squared with the rasp4 ,all kinks and dents are taken out by using the drift plug and driving it through the pipe4 ,take a piece of smooth pine stick and start to beat in the end of the lead pipe to fit the brass ferrule4 ,the pipe should be beaten in starting about #c_/d inches from the end4 ,it should be beaten in very slowly until it fits the ferrule4 ,the pipe is held in the hand all the time and considerable time should be spent on this as it is the first time the beating in of lead pipe has been called for4 ,the knack of doing this comes only by slow and continued practice4 ,the lead must be humored into shape and not driven into shape4 ,the end of the pipe is tapered still more by rasping off the end4 ,about #c_/d inch should extend into the brass ferrule4 ,with the bending irons1 the lead extending into the brass ferrule is beaten against the inside wall of the ferrule4 ,a good way to do this is to wedge the lead pipe in as much as possible at first1 then lay the work flat on the bench1 in which position it is more easily worked4 ,the sketch should be thoroughly studied and each notation be perfectly understood1 before proceeding with the work4 ,now that the lead pipe is perfectly fitted into place1 it is prepared for wiping4 ,the joint overall will be #b-a_/b inches4 ,as we have already allowed #a-a_/d inches on the brass ferrule for the joint1 the lead will have to be cleaned that much more4 ,with the shave hook1 shave the end of the pipe that has been fitted into the brass ferrule4 ,a space about #d inches should be cleaned4 ,this will give a cleaned surface free from dirt and grease for the paste and paper to adhere to4 ,next paste the paper in place4 ,the lead pipe can be entirely covered1 or #c or #d inches only1 above the #a-a_/d inches allowed for the joint4 ,the space between the paper on the brass and the paper on the lead should now be #b-a_/b inches4 ,the paste and paper should now be allowed to dry4 ,,supporting ,,the ,,pipe4--,this joint is wiped with the ferrule down on the bench4 ,a flat pan is laid on the bench and the ferrule stood upon it4 ,a weight on top of the lead pipe is all that is necessary4 ,if this does not make the pipe rigid enough for the beginner1 then a support similar to the round vertical joint support can be used4 ,the beginner is advised1 however1 to practice the wiping of this joint with only the weight to hold it in position4 ,the beginner will then be required to wipe the joint while the solder is hot1 when it does not require a heavy pressure against the solder to wipe it in shape4 ,these wiped joints should be supported in place near the furnace that heats the solder so that the solder will be handy for wiping4 ,illustration3 ,,fig4 #be4--,two-inch brass ferrule4 ,,wiping4--,wiping this joint brings in some of the methods of the round vertical joint4 ,if that joint was thoroughly mastered1 this joint will be wiped considerably more easily4 ,the ladle is held in the right hand and the solder splashed on the joint4 ,the catch cloth is held in the left hand and some of the solder is caught and brought up on the top edge4 ,the top edge cools quickly as all the hot solder runs down to the bottom edge and into the pan4 ,as the solder accumulates on the bottom edge1 it is drawn up on the top edge1 and in this manner the top edge is kept hot4 ,when the solder can be worked freely around the pipe and the edges are hot1 the joint is ready to wipe4 ,the ladle is laid down and the wiping cloth is taken in the right hand and the top edge of the joint cleaned on one side4 ,then the wiping cloth is changed to the left hand and the other side of the top edge is cleaned4 ,holding the cloth in one hand with the index and the third fingers spread to the outside corners of the cloth1 the cloth is passed around the joint quickly4 ,to get an even and symmetrical joint1 it is necessary to make two or three passes around the joint holding the cloth first in the right and then in the left hand4 ,the free hand is used to steady the work4 ,this joint should be wiped very slim to allow room for the caulking irons to pass by it and get into the hub of the pipe4 ,constant wiping on the brass ferrule will result in the tinning on the brass ferrule coming off4 ,the ferrule will look black when this happens and will thus be recognized4 ,the wiping should then be stopped and the ferrule filed and tinned in the same manner as it was done at first4 ,,points ,,to ,,remember4-- ,first1 material--#f inches of #b-;inch light lead pipe and one #b-;inch brass ferrule4 ,second1 tin ferrule1 using soldering iron4 ,third1

except for size4 ,the materials needed for this joint are #f inches of #d-;inch1 #h-pound lead pipe1 and one #d-;inch brass ferrule1 one full pot of solder1 some paste and paper1 rosin1 and #a_/b and #a_/b solder4 ,,tools ,,necessary4--,the tools required for this joint are as follows3 saw1 rasp1 file1 ladle1 soldering iron1 dresser1 bending irons1 shave hook1 and wiping cloths4 ,,preparation4--,lead ,pipe4--,with the saw cut off #f inches of #d-;inch lead pipe4 ,this pipe comes in lengths and should be for this work about #h pounds to the foot in weight4 ,the pipe may be dented badly1 but these dents can be taken out as follows3 ,take a piece of #b-;inch iron pipe and put it in a vise4 ,the lead pipe can be slipped over this iron pipe and any dents taken out easily by beating with the dresser4 ,one end of the lead pipe is beaten with the dresser until it fits into the ferrule4 ,the end is then rasped a little4 ,then1 after the brass ferrule has been tinned1 the pipe is fitted into it and beaten out against the inside wall of the brass ferrule and a tight joint is made4 ,the lead is next cleaned with the shave hook and paper is pasted on as explained under the #b-;inch brass ferrule1 the description of which should now be read over4 ,illustration3 ,,fig4 #bf4--;,four-inch brass ferrule4 ,brass ,ferrule4--,the first thing to do with the brass ferrule is to file the end that is to be wiped4 ,when the brass ferrule is filed1 it should be done away from any part of the room where the filings are likely to get into the solder4 ,after the filing has been done1 paper is pasted on all of it except the part that is to be tinned and no paste must get on to this part of the ferrule4 ,if any paste does get on to it1 the filing will have to be done over again4 ,when using paste and paper1 neatness must be cultivated1 or paste will be spread over parts of the pipe that are supposed not to have any paste on them4 ,next1 take the soldering iron and heat it4 ,take some rosin and put it on the exposed part of the ferrule4 ,with the hot soldering iron proceed to tin the brass ferrule1 as explained before1 with #a_/b and #a_/b solder1 using rosin as a flux4 ,now the lead pipe that has previously been prepared is fitted into the ferrule4 ,,supporting4--,set the brass ferrule on a catch pan4 ,the lead pipe is upright4 ,a weight placed on top of the lead pipe will steady the pipe for wiping4 ,when the joint is wiped the free hand can hold the pipe if the weight is not sufficient to support it4 ,illustration3 ,,fig4 #bg4--;,four-inch brass ferrule4 ,,wiping4--,splash the solder on the joint from the ladle1 in the same manner as was employed in the two preceding joints4 ,to get the proper heat on the #d-;inch joint a little more speed is necessary1 also the constant working of the solder around the pipe4 ,the ladle is constantly moved around the pipe so that all parts of the pipe will be evenly heated and come into contact with the hot solder direct from the ladle4 ,when the solder works freely around the pipe and the top edge is hot1 the joint is shaped by holding the wiping cloth in the right hand1 with the index and the middle fingers spread to the opposite corners of the cloth4 ,the fingers are placed one on the top edge and one on the bottom edge4 ,the cloth is then passed around the joint as far as possible4 ,then the cloth is taken in the left hand1 with the fingers spread1 and passed around the rest of the joint4 ,if the solder does not take the shape of the cloth readily1 then the solder is not at the right heat4 ,this joint should be wiped very slim to allow room for the caulking tools4 ,when this joint is once started1 it should not be left until it has been wiped1 otherwise a large amount of solder will accumulate on the joint and will be hard to get off4 ,,points ,,to ,,remember4-- ,first1 material4 ,second1 tools4 ,third1 tin ferrule4 ,fourth1 use the dresser to fit the lead into the ferrule4

necessary for this job are as follows3 saw1 rasp1 file1 turn plug1 shave hook1 bending irons1 hammer1 ladle1 soldering iron1 and wiping cloths4 ,,preparation4--,there are two joints to be wiped on this job and the stop cock is supported only by the rigid fitting of the lead pipe4 ,therefore the preparation must be thoroughly done4 ,the brass stop will be prepared first4 ,brass4--,the two ends of the stop cock are filed bright1 then papered and tinned4 ,this operation is the same1 only on a smaller scale1 as the tinning of the #b-;inch and the #d-;inch brass ferrule4 ,the paper is pasted over the entire stop cock1 except the two ends1 which are tinned for about #a-a_/d inches4 ,lead ,pipe4--,after the lead pipe has been cut off from the coil1 the ends are squared with the rasp4 ,one end of each piece is reamed out a little with the tap borer and spread a trifle with the turn pin4 ,with the rasp1 take off the outside edge of the end that has been spread4 ,the sketch will show this and give the angle at which the edge is to be rasped4 ,the stop cock is now fitted into the lead pipe4 ,the brass should enter at least #a_/d inch1 then the lead is beaten against the brass until a tight joint is made4 ,the other end of the brass stop is fitted into the other piece of the lead pipe and a perfect fit is made4 ,the fitting of these two joints must be rigid as upon them depends the stability of the joint support4 ,when these ends of the lead pipe have been fitted1 the pipe is cleaned with the shave hook and paper is pasted on1 allowing #a-a_/b inches for the joint4 ,both pieces of pipe are prepared at the same time as both ends are wiped at the same time4 ,,supporting4--,the three pieces of pipe should be so wedged together that they will not fall apart when put in position for wiping4 ,the bricks for supporting the pipe are placed the same as in the support of the horizontal round joint4 ,the lead pipe ends are laid on the bricks4 ,this brings the stop cock in the center without any support4 ,if it were not for the substantial fit between it and the lead pipe1 it would not stay in place4 ,solder straps can be put over each end of the lead pipe4 ,weights can be used to advantage4 ,,wiping4--,when getting the heat up for these joints1 pour the solder over the two joints and over the stop cock4 ,this gets the heat properly distributed1 so that both joints can be wiped while the brass stop is heated4 ,get the proper heat up on one joint and then the other4 ,come back to the first joint and wipe it and then the second one4 ,both joints should be wiped so as to have the same shape4 ,the novice will experience some trouble when wiping this joint in getting the brass edge hot4 ,heating up the two joints together will in a large degree offset this trouble4 ,some mechanics take out the lever handle stop to lessen the amount of brass to heat4 ,this is never done by a good mechanic as the two pieces will never fit together again and make a tight joint4 ,if the plug is left in place1 both the plug and body will expand equally and the pieces will fit perfectly4 ,when wiping is started on these joints1 the beginner must stay at it continually4 ,when the brass is heated1 the finished wiping can be tried over and over again4 ,if this way is not followed1 the beginner will find that most of his time will be spent trying to get a heat on the brass4 ,illustration3 ,,fig4 #bi4--,stop cock4 ,,branch ,,joint ,,materials ,,needed4--,the materials necessary to complete this job are as follows3 #ab inches of #e_/h-;inch extra strong lead pipe for the run2 #f inches of #a_/b-;inch extra strong lead pipe for the branch2 paste and paper1 and solder4 ,,tools ,,necessary4--,the tools necessary for this job are the saw1 bending irons1 rasp1 tap borer1 ladle1 wiping cloths1 and the shave hook4 ,illustration3 ,,fig4 #cj4--;,branch joint4 ,,preparation4--,the preparation of this joint requires the skill of the beginner more than any of the preceding joints4 ,the tapping of the #e_/h pipe for the branch connection1 pasting and cutting the paper1 require the utmost care and precision4 ,the #e_/h-;inch pipe is tapped with the tap borer in the center4 ,the tap borer is used by grasping the handle firmly and putting the cutting point on the mark and then pressing down on the handle4 ,this forces the point into the lead4 ,now turn the tool and a piece of lead will be bored out4 ,continue this operation and a hole will very soon appear in the lead4 ,a hole just large enough to allow the bending irons to enter is made4 ,the opening of the hole is completed with the bending iron1 working the lead back slowly into place4 ,do not attempt to drive the lead back around the hole with a few strokes4 ,one bending iron is inserted and this iron is struck with another iron or hammer4 ,after a number of strokes the opening will be of sufficient size4 ,the bent end of iron is inserted into the hole and the bent part enters the bore of the pipe4 ,this iron is struck in such a way as to force the lead around the hole up1 rather than back4 ,now with the straight end of irons open the sides4 ,when the wall of pipe has been driven up a little the hole can be enlarged by driving back the lead4 ,this procedure will form a collar around the hole to steady the branch pipe4 ,good workmanship will result in having a good substantial collar around the opening4 ,the branch should now be fitted4 ,clean the pipe with the shave hook for about #b inches on each side of the opening4 ,with compasses set at #a-a_/h inches1 mark off a space on each side of the branch on the run1 or on the #e_/h-;inch pipe4 ,on the sides of the pipe the two lines should be joined with an even and symmetrical curve4 ,a good way to make this curve is with the shave hook4 ,now take a folded piece of paper and cut out the shape of one-half of the joint1 then open the fold and the entire ellipse will be made4 ,when this paper is cut1 a sharp knife is used1 otherwise a ragged edge will be made and a good finish of joint is impossible4 ,the paper is now pasted and put on the pipe4 ,the surplus paste on the edge of the paper should be wiped off with the fingers before the paper is put on the pipe4 ,this prevents any paste squeezing out on the joint4 ,the branch is now taken and perfectly fitted into the run4 ,the end is cleaned with the shave hook and paper is pasted on the pipe1 leaving #a-a_/h inches of cleaned surface for wiping4 ,the paste and the paper should now be allowed to dry4 ,the position for wiping this joint is to have the run horizontal and the branch on an angle of #de deg4 pointing away from the wiper4 ,figure #cj will bring out the above explanation very vividly4 ,,supporting4--,the run of this joint is laid flat on the table and the branch inserted in its proper place4 ,with one hand hold it in place1 with the other1 use the bending iron1 tap the collar on the run against the branch1 wedging it in place good and strong so that no solder can leak through4 ,if the branch is tapered with the rasp as shown the joint can be made very tight4 ,the run of the pipe is now laid on two bricks as was done with the horizontal joint4 ,the branch is laid over on a pile of bricks or wood at an angle of #de deg4 ,the best way to secure this joint is to pour some half-molten solder on the ends of pipe and brick1 making a solder clamp4 ,this branch does not need any clamp or weight if it is properly entered into the run4 ,a strap of solder can be run over the end of pipe if found necessary4 ,place the catch pan under the joint and then the pipe will be ready to wipe4 ,,wiping4--,in wiping this joint1 the catch cloth is used not only to catch the solder as it drops off from the pipe1 but also to hold the hot solder against the pipe to heat the under side of the joint4 ,test the solder and see if it is the correct heat for wiping4 ,if so1 prepare for wiping4 ,after heating the ladle1 take some solder in it and proceed to drop the molten solder on the joint4 ,the ladle is moved constantly as the solder is dropped on the run and then on the branch to get the entire joint to the proper heat4 ,as the solder drops off from the joint1 it is caught on the catch cloth and brought up on the top of the joint where it is re-melted by dropping hot solder on it4 ,then the hot solder is held in the cloth against the under side of the joint to get the under side properly heated4 ,the solder is worked around all parts of the joint4 ,when the heat is got up sufficiently and the solder works freely around the joint1 the branch cloth is taken and each edge of the joint is wiped clean4 ,any surplus solder is brought up on top of the joint and then wiped on the catch cloth4 ,this solder is then put on the under side of the joint4 ,with the branch cloth reach way around the joint and wipe each side1 bringing the cloth each time to the top and then off the joint4 ,the last wipe is directly across the top1 wiping off any surplus solder that may have accumulated from wiping the sides4 ,the difficulty with this joint is in getting the top and bottom to have an equal amount of solder4 ,with a little practice and by watching each motion your faults can be noted and remedied4 ,if the paper starts to come off1 it should be re-papered at once4 ,when the joint is finished1 it should be left in position until the solder has had time to set and cool1 otherwise the branch will break off and considerable time will be lost in correcting the trouble4 ,,points ,,to ,,remember4-- ,first1 the use of the tap borer4 ,second1 the use of the bending irons4 ,third1 do not allow the bending irons to touch the inside walls of the pipe when stretching the opening4 ,fourth1 secure the branch into the run4 ,fifth1 secure the pipes into position for wiping4 ,sixth1 spread the heat on the edges and the bottom of the joint4 ,seventh1 wipe with the branch cloth4 ,eighth1 cut the paper4 ,ninth1 mark the outline of the joint4 ,,branch ,,joint ,,placed ,,flat ,when the wiper has mastered the branch joint placed at an angle of #de deg41 he can proceed to wipe the joint placed in the next position1 which is flat4 ,,preparation4--,the preparation of this joint is identical with the preceding one placed at an angle of #de deg4 ,if a new joint is to be prepared1 it would be well to pay strict attention to the details1 such as keeping the paste on the paper only and having the edge of the paper cut perfectly smooth and even4 ,before putting on the paper see that the pipe is free from all grease and dirt4 ,the paste and paper will stick better if all the dirt is removed4 ,the branch should be well fitted into the run of the pipe so that no solder will get into the bore of the pipe4 ,the branch should not extend into the run of pipe enough to obstruct the bore of it4 ,if the instructions for preparing the pipe are not carried out as detailed1 the wiper will experience some trouble that he may find hard to overcome4 ,,supporting4--,the run can be supported on bricks4 ,the branch can be supported on a brick placed at its end the same height as the run4 ,this will bring the joint in the correct flat position4 ,the branch should point away from the wiper4 ,solder straps can now be poured over the ends of each pipe4 ,if weights are used to hold the pipe firm instead of solder straps1 they should be so placed that they will not interfere with the hands when wiping4 ,,wiping4--,the wiping of this joint is more difficult as the beginner will experience trouble in heating the bottom and keeping the solder on the bottom4 ,solder is dropped on the joint and along the pipe so as to bring the pipe to the proper wiping heat4 ,some solder will accumulate on top of the joint4 ,this is melted off on the catch cloth and this hot solder held against the bottom of the joint4 ,this operation is repeated until the bottom as well as the top of the joint is heated properly4 ,when the solder can be worked freely around the pipe1 the branch cloth is taken and each side is wiped from the bottom toward the top4 ,solder is accumulated on the top where it is wiped off on the catch cloth and put on the bottom of the joint4 ,now reach way around each side and wipe the edge and body of the joint1 a wipe across the top completing the joint4 ,the bottom can be wiped with a cross wipe also if desired4 ,the top and the bottom should be identical4 ,notice carefully the drawing of this joint and endeavor to have the same lines4 ,the perfecting of these joints comes only with patient practice4 ,the beginner must not get discouraged because of a burn or two4 ,as soon as confidence in oneself has been gained1 the possibility of burning the fingers is entirely eliminated4 ,,branch ,,vertical ,the materials1 tools1 and preparation for this joint placed in a vertical position are just the same1 practically1 as those in the preceding branch joints4 ,one or two points wherein they differ are mentioned below4 ,to rigidly support the joint for wiping1 allow the run of the pipe to rest on some bricks as before mentioned1 with the branch looking up4 ,now take a piece of wood and drive a nail through one end of it about #a inch from the edge4 ,let this nail enter the bore of the vertical branch4 ,the wood is allowed to rest on the back of the bench or is braced against the wall4 ,supporting the pipes in this way will allow the wiper perfect freedom4 ,when wiping this joint1 splash the solder on from the ladle as on the upright joint4 ,as all the sides of this joint can be seen1 it is not a difficult matter to make a perfectly symmetrical solder bulb4 ,when the proper heat is gained1 the top edge of the joint is wiped first1 then the lower curved edge1 using the branch cloth4 ,the body of the joint is then wiped and the joint finished with a cross wipe1 if necessary4 ,,branch ,,horizontal ,the next position for this joint is to have the branch pipe horizontal and the run vertical4 ,the materials1 tools and preparation for this joint are the same as for the preceding ones4 ,the supporting and wiping differ a little4 ,,supporting4--,one end of the run is placed on the catch pan4 ,the other end is held in place the same way as the branch was held in the preceding joint4 ,if the pictures of this joint are carefully looked over1 the methods employed to hold the pipe will be readily noted4 ,the branch is best held by inserting one end of a bending iron in the bore of the pipe and placing the other end of the iron on a brick built up to the right height4 ,the iron should be weighted to keep the joint from swaying4 ,,wiping4--,the solder is now dropped on the branch as in the round joint1 and splashed on the vertical run as in the upright joint4 ,sufficient solder is put on the joint to keep the edges covered with hot solder4 ,solder is worked around the joint until all parts of it are thoroughly heated and the solder works easily1 then all the edges are wiped clean4 ,the top half is then wiped evenly and the bottom half wiped to match the top half4 ,a cross wipe in front completes the joint4 ,when this cross wipe is made on any joint1 a thick edge of solder must not be left4 ,the edge must be wiped clean4 ,this joint should be wiped first with the branch pointing to the right and then with the branch pointing to the left4 ,it will take the beginner some time to master these branch joints1 for not only must they be wiped symmetrically for the sake of appearances1 but they must be wiped while the solder is hot to secure a tight joint4 ,a joint that is wiped with solder that is too cold will be porous and will leak when put under pressure4 ,with care the same pipe can be used throughout for all the positions of this branch joint4 ,,one ,,and ,,one-,,half-,,inch ,,branch ,,joint ,upon the completion of the small sized branch joint in its various angles1 the #a-a_/b-;inch branch joint is to be wiped4 ,this branch joint is wiped in the same positions as the #e_/h branch was wiped4 ,the pipe being larger1 there is more solder for the wiper to handle1 and the edges to keep clean and to wipe are longer4 ,,materials ,,needed4--,the materials needed for this job are #ab inches of #a-a_/b-;inch light lead pipe for the run1 and #f inches of #a-a_/b-;inch pipe for the branch1 paste1 paper1 solder1 and catch pan4 ,,tools ,,needed4--,the tools necessary for this job are the saw1 rasp1 shave hook1 bending irons1 drift plug1 hammer1 ladle1 wiping cloths1 and tap borer4 ,,preparation4--,to an experienced wiper1 the procedure of preparing this joint and wiping it are so near like the #e_/h-;branch joint that a detailed description would be unnecessary2 but for the benefit of the beginner1 ,i will repeat the details as they apply to this particular joint and thereby avoid any error4 ,we will take the preparation of the run first4 ,square the two ends of the pipe with the rasp4 ,mark off the center of the pipe4 ,with the round part of the rasp1 held at right angles with the pipe1 proceed to rasp down the crown of pipe where the center mark was made4 ,do not rasp through the wall of the pipe1 but just enough so that the tap borer will enter the pipe with only a slight pressure4 ,with the tap borer1 tap a hole large enough for the bending irons to enter4 ,now proceed to enlarge the hole1 first forcing the edges up and then forcing them back1 making the hole larger and making a collar around the hole at the same time4 ,continue to open the pipe until the aperture is large enough for the branch pipe to enter4 ,the bending irons must not come into contact with the inside wall of the pipe1 for if they do the inside bore will be marred and be very ragged4 ,as these joints are usually used on waste lines1 these ragged places make an ideal place for lint and grease to collect and cause a stoppage4 ,to make the inside of the hole even1 a piece of #a_/b-;inch pipe can be used in place of the bending irons4 ,to cut out the oval from a piece of paper to fit the joint1 fold the paper and cut out one-half of the oval4 ,now unfold the paper and the complete oval is obtained4 ,the measurements of the oval are taken from ,fig4 #cj1 #a-a_/h inches each side of the branch lengthwise of the run4 ,these two lines are connected with a curved line as shown4 ,this curved line can be made with the shave hook4 ,take the large edge of the shave hook and roll it along between the lines to be joined4 ,a little practice will perfect one in doing this quickly4 ,the beginner should make a number of these ovals so that he can get them perfect4 ,the graceful appearance of this joint depends upon the neatness with which it is prepared4 ,i do not want the beginner to think that a graceful shape of the joint is all that is to be desired or that it is the most essential point4 ,further along1 perhaps1 more vital requirements will be brought out and the beginner will be made acquainted with them4 ,the ends of the #f-;inch piece are now squared with the rasp4 ,the edges of one end are rasped off as shown in the sketch1 making a wedged fit into the run4 ,this end is then cleaned with the shave hook4 ,paper is then pasted on to cover the pipe except the #a-a_/h inches cleaned on the end4 ,this cleaned part forms part of the joint1 therefore no paste or paper must be put on it4 ,the pipe is now fitted into the run and the collar beaten against it with the bending irons4 ,the run is now cleaned with the shave hook for about #c inches each side of the center4 ,the paper oval cut out is now pasted on the joint4 ,the paste and paper are then allowed to dry before they are handled further4 ,,supporting4--,the supporting of this joint1 which is placed with the branch on an angle of #de deg4 pointing away from the wiper1 is not a difficult matter4 ,the beginner can use his own ingenuity for supporting the pipe if conditions do not warrant the using of the methods previously described4 ,,wiping4--,the solder should now be tested for heat4 ,if the solder is at the proper heat1 the ladle is taken and heated4 ,take a ladle full of solder and drop the solder on the joint4 ,the lead of which this branch joint is made is considerably lighter than any lead that has been used before4 ,therefore1 the beginner must drop the solder on carefully1 making sure that the solder is not dropped on the same spot1 for a hole can be burned through the pipe very quickly4 ,the ladle must be kept moving1 then the solder will not burn through the pipe4 ,the heat is got up on the pipe by dropping the solder on the run and on the branch1 catching the surplus solder on the catch cloth and heating the under side of the joint with it4 ,to form the joint1 distribute the solder and then wipe it into shape4 ,notice that ,i said wipe it into shape4 ,a beginner is very apt to try to push or poke it into shape4 ,this must not be done as it has a tendency to make the joint lumpy4 ,all the edges are wiped off clean first1 then the body of the joint is shaped and wiped4 ,when forming the joint1 be sure that the bottom and the top are symmetrical4 ,do not have one-half larger than the other4 ,the last wiping strokes are made swiftly and rapidly4 ,if the wiper will watch his movements and note the results and then try to improve them1 keeping in mind that a symmetrical joint is wanted with thin edges1 perfection in wiping will come much more quickly than if no attention is paid to the strokes made when wiping4 ,,branch ,,joint ,,wiped ,,flat ,the materials required for this joint do not differ from the preceding one4 ,if the pipe used for the branch joint at a #de deg4 angle is in good shape1 it can be used for this joint by simply changing positions4 ,the tools needed will not be any different4 ,the ladle and the wiping cloths1 of course will be required4 ,a pair of pliers can be used to advantage in picking up the hot solder4 ,the wiping cloths should receive a little more oil to keep them soft and pliable4 ,oil the edges of the cloths well4 ,,supporting4--,to support this pipe for wiping have each end rest on a brick4 ,each end can be weighted to hold it in place4 ,,wiping4--,to wipe this joint1 proceed to drop the solder on the joint4 ,when the pipe is thoroughly heated and the solder works freely around the pipe the joint can be wiped4 ,the procedure is like the preceding one4 ,the wiper is cautioned to move the ladle constantly while dropping the solder4 ,,branch ,,held ,,vertical ,after a number of the previous joints have been wiped successfully1 the pipe is placed in such a position that the branch will be vertical4 ,the supporting of the pipe to hold the joint in this position for wiping is very easily done after handling the #e_/h-;in4 joint in this position4 ,the following points may be found helpful3 ,the solder is splashed on the joint from the ladle4 ,the top edge of the joint is kept hot by keeping the solder covering it4 ,when the proper heat has been got up1 the top edge is wiped first1 then the bottom edges both front and back4 ,the body of the joint is wiped last and a cross wipe finishes the joint4 ,i have found that the beginner in many cases1 when this joint is reached1 tries to wipe it with many short strokes4 ,the habit is a bad one and should be stopped as soon as noticed4 ,learn to wipe the top edge with only two strokes1 the bottom edge with not more than four1 the body of the joint with four1 and one cross wipe to finish4 ,this joint should be finished as symmetrically as possible and wiped while the solder is hot4 ,,run ,,held ,,vertically ,when the vertical branch has been conquered and the wiper can get a good joint every time it is tried1 the pipe can be changed to a different position4 ,the run is placed in a vertical position and the branch horizontally to the left4 ,the catch pan is put under the end of the pipe4 ,follow the same directions for supporting this joint as were given under the #e_/h-;in4 branch placed in a similar position4 ,the wiping of this joint is so nearly like the preceding branch joints that ,i will not give any instructions at all4 ,this joint is finished at the same point that the other branch joints are finished4 ,however1 there are one or two matters that should be kept in mind4 ,some of the small matters are often overlooked and should be called to mind occasionally4 ,do not allow the solder to accumulate in the pan4 ,if the cloths are burned1 they should be turned1 or new ones made4 ,if the paper has started to come off from the pipe1 new paper should be put on at once4 ,test the solder occasionally and see that it does not get too hot4 ,upon completion of the joint in this position1 the branch joint in its various positions is finished4 ,the beginner has found out while wiping these various joints a number of points that were not mentioned in my description4 ,no amount of detailed description will make a good joint wiper4 ,patience and practice are as important in joint wiping as good preparation and good solder4 ,,points ,,to ,,remember4-- ,first1 materials--#ah inches of #a-a_/b-;in4 lead pipe4 ,second1 use of tools4 ,third1 keep bending irons away from the wall of the pipe4 ,fourth1 make a good collar around the opening4 ,fifth1 make a tight fit with branch and run4 ,sixth1 hot solder will quickly burn through the lead4 ,seventh1 use branch cloth for wiping4 ,eighth1 cut out paper for joint even and symmetrical4 ,,bib ,this joint is another brass to lead1 and is the last single joint to be wiped in this course of joint wiping4 ,,materials ,,needed4--,the materials required for this joint are as follows3 #aj inches of #e_/h-;inch extra strong lead pipe2 one #a_/b-;inch brass sink bib for lead pipe2 one pot of solder1 paste and paper1 #a_/b and #a_/b solder1 catch pan1 and supports4 ,illustration3 ,,fig4 #ca4 ,,tools ,,required4--,the tools required for this job are the saw1 rasp1 tap borer1 bending irons1 file1 ladle1 wiping cloths1 shave hook1 knife and rule1 soldering iron4 ,,preparation4--,to prepare the lead pipe after cutting from the coil and squaring the ends with the rasp is very similar to the #e_/h-;inch branch joint4 ,the center of the pipe is marked and a hole is made in it with the tap borer large enough to admit the bending irons4 ,the hole is enlarged with the irons4 ,a good substantial collar is made around the hole to hold the bib in place4 ,one and one-eighth inches are marked off on each side of the branch and an easy curve connects the two4 ,the paper is then cut out and pasted on the pipe after it has been scraped with the shave hook4 ,the end of the brass bib is filed bright and tinned with the soldering iron and #a_/b and #a_/b solder4 ,before the tinning is done1 paper is put on the brass1 leaving only #a-a_/h inches exposed4 ,the tinning must be thoroughly done1 or it will come off and have to be re-tinned4 ,,supporting4--,the bib is fitted into the lead opening and the collar is forced against the bib to hold it in place and prevent any solder from leaking through into the bore of the pipe4 ,the bib must not extend too far into the lead pipe or it will obstruct the flow of water4 ,the lead pipe is laid on two bricks the same as the round joint4 ,the bib is laid on an angle of #de deg4 pointing away from the wiper4 ,some bricks can be piled up to the right height to hold the bib in place and a solder strap can be made to hold it steady4 ,the lead pipe can be held steady by weighting each end4 ,the catch pan is now placed under the joint and everything is ready for wiping4 ,illustration3 ,,fig4 #cb4--;,bib4 ,,wiping4--,when the solder is hot1 getting the heat on the pipe is started4 ,solder should be dropped oftener on the brass bib than on the lead pipe4 ,it takes more heat to heat the brass thoroughly than it does the lead4 ,if this is followed out1 little difficulty will be had in getting up the heat and in wiping4 ,use the branch cloth for wiping and make sure that all edges are perfectly cleaned before making the final strokes4 ,as this is the only position that the joint will be wiped in1 practice should be continued until perfect joints can be obtained4 ,,points ,,to ,,remember4-- ,first1 materials needed4 ,second1 tools needed4 ,third1 use tap borer4 ,fourth1 enlarge hole with bending irons4 ,fifth1 make substantial collar around the opening4 ,sixth1 paper the lead4 ,seventh1 file the bib1 then paper4 ,eighth1 tin the bib4 ,ninth1 place in position and wipe4 ,,drum ,,trap ,the making of the drum trap will bring out the skill of the beginner4 ,the entire trap is made of lead pipe4 ,the lead will require a great deal of handling4 ,therefore1 care must be exercised in all operations to turn the trap out in a workmanlike manner4 ,,materials ,,needed4--,the materials needed to complete this job are3 #aj inches of #d-;inch #h-pound lead pipe2 #ah inches of #a-a_/b-;inch light lead pipe2 paste and paper1 support1 solder1 and catch pan4 ,,tools ,,needed4--,the tools required for this job are3 saw1 rasp1 bending irons1 shave hook1 bending spring1 tap borer1 dresser1 ladle1 drift plug1 and wiping cloths4 ,illustration3 ,,fig4 #cc4--;,drum trap4 ,,preparing4--,take the #aj-;inch piece of lead pipe and hold it in one hand1 in the other hand take a pine dresser4 ,strike the lead pipe with the dresser4 ,the pipe is struck about #b inches from the end and is beaten evenly all around4 ,the pipe is then struck nearer the end until finally the bore of the pipe is almost closed4 ,this closed end should be rounding and symmetrical4 ,to get this shape the pipe must be continually moved and turned4 ,one side must not be forced in more than the other4 ,if there are any dents in the pipe or part of the pipe is forced in too much it may be driven out as follows3 ,take an old piece of #a_/b-;inch lead pipe and round one end of it with a hammer2 this can be used by hitting the inside of the closed end of the drum and forcing out the dents4 ,the rounded end of the trap is not quite closed and a hole about #c_/d inch is left4 ,this opening is closed by shaping the edges of it with the knife1 making them smooth and beveled4 ,then a piece of lead is cut out of some scrap1 the same shape as the hole and fitted into it4 ,the top surface of this fitted piece should be a little lower than the surface of the pipe4 ,strike a circle1 using the compasses1 the center of the circle being the center of the inserted piece of lead4 ,the lead inside of this circle is shaved clean with the shave hook1 including the inserted piece4 ,paper is then pasted outside of the circle and should cover entirely the rest of the pipe4 ,the inserted piece is wiped on the pipe as follows3 ,,wiping ,,end4--,stand the #d-;in4 pipe in a pan with the rounded end of the pipe up4 ,be sure that the inserted piece is fitted securely4 ,the solder is now dropped on the paper and shaved portion of the pipe4 ,exercise considerable care not to burn a hole in the pipe4 ,as the hot solder runs off1 catch some of it and draw it back on the joint4 ,when the solder can be manipulated freely and the pipe is hot1 the joint can be wiped4 ,the cloth is drawn across the joint1 cleaning all the edges with one stroke4 ,the joint should be shaped to complete the rounding surface of the pipe4 ,the joint is comparatively easy and will not occupy much time4 ,as soon as it is wiped1 cover the solder with paper4 ,this will preserve the freshness of the joint until all wiping is completed4 ,,preparing ,,inlet ,,pipe ,after the above joint is completed1 the #a-a_/b-;in4 branch inlet pipe is prepared and wiped in place4 ,the center of this branch is marked on the #d-;inch pipe and a hole is tapped in the pipe1 using the tap borer4 ,a hole large enough to admit the bending irons is made4 ,the hole is enlarged with the bending irons1 bending the lead first up1 then back4 ,a piece of #a_/b-;inch iron pipe can be used as a tool to finish the opening4 ,the iron pipe is larger in diameter than the bending irons and leaves a more finished surface4 ,the opening is made of sufficient size to admit the rasped end of the #a-a_/b-;inch pipe4 ,when using the irons to enlarge the opening in the pipe1 be sure not to bruise any part of the trap4 ,the #a-a_/b-;inch pipe is now taken4 ,the ends of this pipe are squared with the rasp4 ,the drift plug is then driven through the pipe to take out any bruises or flattened places4 ,the edge of one end is rasped off to fit the opening made in the #d-;inch pipe4 ,the beginner must strive to make a perfect fit4 ,the accuracy with which these preparations are made is what helps in a large degree to bring about a successful job4 ,the next operation is to paper the parts not to be wiped4 ,the sizes of the joint should be followed as shown on the sketch4 ,the pipe is first shaved with the shave hook1 after which the paper is pasted on4 ,no paste is allowed to get on the joint proper4 ,the beginner should by this time have formed the habit of being neat with his work4 ,therefore the getting of paste on the joint surface shows that he is not as neat or as far advanced as he should be4 ,,supporting4--,the drum is laid lengthwise on the bench and blocks are put on each side to keep it from rolling1 the branch uppermost4 ,the #a-a_/b-;inch pipe is held in position the same way as the vertical branch was held4 ,the catch pan is put under the drum to catch the surplus solder4 ,,wiping4--,splash the solder on the branch pipe1 also on the drum4 ,the burning through of the drum is an easy matter4 ,therefore do not keep dropping the solder on one place1 but keep the ladle moving continually4 ,with the catch cloth draw the solder up on the branch covering the top edge of the prepared surface4 ,splashing the solder on this top edge melts the solder already on and allows it to run down on the #d-;inch pipe where it is caught with the cloth and again brought up on the top edge of the branch4 ,when the solder works freely all around the joint1 the top edge is wiped clean and even4 ,then any surplus solder is wiped off4 ,the bottom edge is next wiped clean1 after which the body of the joint is wiped into shape1 together with both edges4 ,the edges are wiped very thin so that when the paper is removed the outline of the joint stands out very distinctly4 ,a thick edge on a joint gives an unworkmanlike appearance to the work4 ,the joint is finished with a cross wipe4 ,the other joints are prepared and wiped the same as the one just completed4 ,the #a-a_/b-;inch branch connection taken out of the bottom of the trap is bent4 ,as this is the first time it has been necessary to bend lead pipe in these jobs1 ,i will cover this operation in detail4 ,the pipe is first straightened and the drift plug driven through it4 ,the pipe is marked where the bend is to be made4 ,the bending spring1 size #a-a_/b inches1 is put into the pipe1 the center of the spring coming about where the bend is to be made4 ,the pipe is then heated where it was marked to be bent4 ,the proper heat for this pipe is just so that the hand cannot stand being laid against it4 ,the pipe is held in the hands and on the end nearest the heat is hit against the floor at an angle4 ,the pipe1 with the first blow1 will start to bend4 ,with a few more strokes the desired bend will be obtained4 ,the bending spring can now be pulled out4 ,put a little water in the pipe1 then put one end of the spring in the vise1 twist the pipe1 and the spring will come out when the pipe is pulled away from it4 ,the bending spring holds the pipe cylindrical while it is being bent4 ,without the spring1 the pipe would be badly crushed at the bend and rendered almost unfit for service4 ,another good way to bend pipe is to plug one end and fill the pipe full of sand1 then plug the open end4 ,the pipe is then heated where the bend is to be made4 ,the pipe can then be bent over the knee4 ,when all the joints are wiped1 the paper should be taken off and the lead cleaned with sand and water4 ,the trap is now complete except the brass clean-out to be soldered on the top4 ,the inside of the trap should not have any rough edges or drops of solder in it4 ,illustration3 ,,fig4 #cd4--;,drum trap4 ,there are two other drum traps to be made4 ,the materials needed are the same as for the above trap except for #ah inches more of #a-a_/b-;inch lead pipe4 ,the support1 preparation1 and wiping are the same4 ,the beginner by this time should feel very well acquainted with lead and solder4 ,therefore1 the details of these two drum traps can be left for the beginner to work out for himself4 ,the sketches are very distinct and readable and will be of considerable assistance4 ,the beginner should make these traps4 ,,points ,,to ,,be ,,remembered4-- ,first1 use #d-;inch lead pipe1 #h pounds to the foot4 ,second1 dresser and spring are new tools4 ,study their use4 ,third1 gradually work the trap into shape with the dresser4 ,fourth1 plug the hole with a piece of lead pipe4 ,fifth1 prepare and wipe the plugged hole first4 ,sixth1 prepare and wipe the #a-a_/b-;inch branches4 ,seventh1 special care should be taken to keep the work neat4 ,eighth1 two ways of using the bending spring4 ,ninth1 wipe thin edges on joints4 ,tenth1 do not handle finished work4 ,eleventh1 clean and finish the work neatly4 ,,the ,,practical ,,use ,,of ,,the ,,preceding ,,exercises ,in the foregoing exercises1 ,i have confined myself to the actual work of making the various joints4 ,now ,i will explain the practical use of them4 ,,soldering ,,iron4--,the soldering iron is a tool that is used in work that requires heat to fuse solder and the parts to be united4 ,every plumber should have at least two irons in his kit4 ,,the ,,cup ,,joint4--,while the cup joint is not employed to any great extent in modern plumbing1 yet it has its use in the installation of some fixtures4 ,lavatories1 bath and toilets are sometimes connected with a short piece of lead on the supply4 ,the tail pieces on the faucets can be soldered on the lead by means of a cup joint4 ,a cup joint well made with a deep cup and the solder well fused is as strong as a wiped joint in a place of this kind4 ,the evil of the cup joint is that some mechanics will only fuse the surface and leave the deep cup only filled with solder and not fused4 ,this makes a tight joint1 but extremely weak4 ,on tin-lined pipe and block-tin pipe the cup joint is commonly used4 ,when making a cup joint on block-tin pipe the soldering iron must not touch the pipe and fine solder should be used4 ,when tin-lined pipe is being soldered1 the tin lining must not be melted4 ,,overcast ,,joint4--,the overcast joint is not commonly used1 but when there is considerable lead work to do the plumber finds it very handy in places where a wiped joint would take up too much room4 ,we use it for an exercise for the reason that it teaches the beginner very rapidly the use and control of the soldering iron4 ,,flat ,,seams4--,these seams are used in the construction of roof flashers1 tanks 7,sec4 #cc1 ,chapter ,,xviii7 and lead safe wastes 7,sec4 #bg1 plumbing code74 ,a hatchet iron is sometimes used on these seams4 ,,wiping ,,cloths4--,the wiping cloths made of whalebone ticking make good1 serviceable1 and lasting cloths4 ,oil only should be used to break the cloth in4 ,moleskin cloths are very good1 but they are very hard to get and cost considerably more4 ,a plumber should always keep a good supply of ticking cloths on hand4 ,the cloths are used only for wiping4 #a_/b-;,,inch ,,round ,,joint4--,this joint is the one most often required in actual practice4 ,it serves to connect two pieces of lead pipe of the same or different diameters4 ,it is also used to connect lead and other materials of which pipe is made4 ,the workman1 when he gets out on the job1 finds that his work cannot be supported for wiping in such an easy and convenient position as illustrated in the exercises4 ,it will be necessary to wipe the joint at almost every conceivable angle and position4 ,the workman must employ his ingenuity to overcome any difficulties that may arise4 ,any draught of air should be avoided as it will make the solder cool quickly4 #b-;,,inch ,,brass ,,ferrule4--,when it is found necessary to connect cast-iron and lead pipe1 it is done by means of a brass ferrule wiped on the lead pipe4 ,this joint is a very common joint and is found on sink1 tray1 and bath connections1 as well as in many other connections that have lead and cast-iron pipes for wastes4 #d-;,,inch ,,brass ,,ferrule4--,the #d-;inch brass ferrule wiped on lead pipe is found under almost every closet4 ,there is generally a piece of lead connecting the toilet with the soil pipe4 ,therefore1 a brass ferrule is wiped on the lead and the ferrule connected with the soil pipe4 ,this joint is also found on rain leader connections near the roof1 connecting the gutter with the rain leader stack4 ,,stop ,,cock4--,when a shut-off is required in a line of lead water pipe1 these joints are used4 ,where it is necessary to joint lead and brass1 this joint is required4 ,the art of heat control over the lead and the brass is the essential point in these joints4 ,,branch ,,joints #e_/h ,,and #a_/b ,,inches4--,where it is found necessary to take a branch from a water pipe1 this joint is used at the connection4 ,in practice1 this joint may have to be wiped in positions that are rather difficult to reach1 so the wiping of joints in the positions called for in the exercises is exceedingly good practice4 ,,branch ,,joints #a-a_/b ,,inches4--,these joints are very common and are found on waste and vent pipes4 ,they are also found on urinal flush-pipe connections where the branch often is brass and the run lead4 ,,bib4--,when lead supplies are run directly to the bib on a sink1 this joint is necessary4 ,it becomes necessary to wipe in a piece of brass for a brass-pipe connection from a lead pipe1 in which case this joint is called for4 ,,the ,,drum ,,trap4--,the drum trap is used under sinks1 baths1 showers1 and trays4 ,,chapter ,,vii ,,laying ,,terra-,,cotta ,,and ,,making ,,connections ,,to ,,public ,,sewers4 ,,water ,,connections ,,to ,,mains ,,in ,,streets ,,terra-,,cotta ,,pipe ,one of the first pieces of work which a plumber is called upon to do1 when building operations commence1 is to run in the terra-cotta sewer from the street sewer into the foundation wall4 ,illustration3 ,,fig4 #ce4--;,connection of house sewer to main sewer4 ,when the street sewer is laid1 ,y-branches are left every few feet4 ,a record of the branches and their distance from the manhole is kept generally in the ,department of ,sewers or ,public ,works4 ,therefore1 the exact measurement of any branch can be obtained and the branch found by digging down to the depth of the sewer4 ,a branch should be chosen so that the pipe can be laid with a pitch1 the same way as the main sewer pitches4 ,this can be done by getting the measurements of two of these branches and choosing the one that will serve best4 ,when there is a brick sewer in the street and no branches left out1 the sewer must be tapped wherever the house sewer requires it 7see ,fig4 #ce74 ,,digging ,,trenches4--,after the measurements and location of the house sewer and sewer branches are properly located1 the digging of the trench is started4 ,the methods employed to dig the trench vary according to the nature of the ground1 that is1 whether it is sand1 rock1 or wet ground4 ,a line should be struck from sewer to foundation wall to insure a straight trench4 ,illustration3 ,,fig4 #cf4--,laying of plank for trench dug in sandy ground4 ,,sandy ,,ground4--,if the ground is sandy1 the sides of the trench will have to be sheathed or planked and the planks braced so as to prevent the bank caving in4 ,as the trench is dug deeper1 the planks are driven down4 ,when the trench is very deep1 a second row of planking is necessary4 ,the planks must be kept well down to the bottom of the trench and close together1 otherwise the sand will run in4 ,it is well to test the planking as progress is made by tamping the sand on the bank side of the planks4 ,,gravel4--,where the ground is mostly gravel and well packed1 the above method of planking is unnecessary4 ,the bank should have a few stringers and braces to support it4 ,when only a few planks are used the term corduroy the bank is used 7see ,fig4 #cg74 ,illustration3 ,,fig4 #cg4--;,arrangement of plank for gravel4 ,,rock4--,where rock is encountered1 blasting is resorted to4 ,the plumber should not attempt to handle a job requiring the use of powder4 ,it is dangerous in the hands of a person not used to handling it and the work should be sublet4 ,a sketch of the two methods above for planking trenches is given and a little study will make them clear4 ,,laying ,,of ,,pipe ,the pipe should be laid on the bottom of the trench to a pitch of at least #a_/d inch per foot fall4 ,in laying1 the start should be made at the street sewer with hubs of pipe toward the building4 ,the trench should be dug within a few inches of the bottom of the pipe1 then as the pipe is laid the exact depth is dug out1 the surplus dirt being thrown on the pipe already laid4 ,the body length of pipe should be on solid foundation4 ,a space dug out for each hub as shown in ,fig4 #ch allows for this1 also allows for the proper cementing of joints4 ,to get the proper pitch of pipe1 take for example #a_/d inch per foot1 a level #b feet long with a piece of wood or metal on one end #a_/b inch thick will answer4 ,the end with the #a_/b-;inch piece on should be on the lower hub and the other end resting on the hub of the pipe about to be put in place4 ,when the bubble shows level1 then the pipe has the #a_/d-;inch fall per foot4 ,if a tile trap is used1 it should be laid level1 otherwise the seal will be weakened or entirely broken4 ,illustration3 ,,fig4 #ch4--,laying terra-cotta pipe4 ,,cutting4--,the cutting of tile is not difficult1 but must be done carefully or the pipe will crack or a piece will be broken out1 thus making the pipe worthless4 ,to cut tile or terra-cotta pipe1 stand the pipe on end with the hub down1 fill the pipe with sand to the point of cutting4 ,with a sharp chisel and hammer cut around the pipe two or three times and the pipe will crack around practically straight4 ,,cementing4--,if the pipe is free from cracks1 the only possible way roots can get into the inside of terra-cotta pipe is through the cement joint4 ,there are two ways of making these joints4 ,both ways are explained below and are used today on terra-cotta work4 ,first4--,the bottom of the hub of pipe in place is filled with cement and the straight end of the next piece of pipe is laid in place1 then more cement is placed into the hub until the space between the hub and the pipe is filled4 ,in a trench1 a trowel is rather unhandy to work with1 while the hands can be used to better advantage4 ,the cement can be forced into place with the hands and then surfaced with a trowel4 ,the rest of the operation is to swab out the inside joint to remove any cement that perchance was forced through the joint 7see ,fig4 #ci74 ,the cement used should be #a_/b cement and #a_/b clean sharp sand4 ,second4--,half of the space between the hub and the pipe is first packed with oakum and then the other half filled with cement of the same proportions as that used above4 ,illustration3 ,,fig4 #ci4--,showing use of the swab4 ,,laying ,,pipe ,,in ,,tunnels ,illustration3 ,,fig4 #dj4--,pushing pipe through tunnel4 ,if the pipe must be run through a tunnel and there are perhaps three or four joints that cannot be reached1 they should be put into place as follows3 ,the pipe should be laid in the trench from the sewer in the street as far as the tunnel1 then start at the other end of the tunnel4 ,lay the first piece of pipe on a board1 lengthwise with the board1 nail two cleats in the shape of a 7,fig4 #dj7 for the pipe to rest in2 push this pipe and board into the tunnel and then cement into its hub a second piece2 push the two pieces in #b feet1 cement a third length into the second piece and push the three pieces along #b feet4 ,a workman can be on the sewer side of the tunnel and receive the end of the pipe as it is pushed through the tunnel1 and steer the pipe into the hub4 ,the joints in the tunnel will not be as secure as those outside4 ,this explains how pipe is run through a tunnel4 ,,connecting4--,the proper method of connecting the house sewer with the street sewer is shown in ,fig4 #ce4 ,the connection should be made above the spring of the arch4 ,the pipe should extend well into the sewer so the sewage will discharge into water and not drop on sides4 ,,inserting4--,to insert a tee in a line of pipe already laid1 pursue the following method 7see ,fig4 #da73 ,cut or break out one joint1 preserve the bottom of the hub of pipe that is in4 ,cut away the top of the hub on the pipe to be inserted1 then place the pipe in position and turn around until the part of the hub on the piece inserted is on the bottom4 ,the bottom part of the pipes now will have a hub to receive the cement4 ,the top part will have to be cemented carefully1 as it is within easy access4 ,this can be done without difficulty4 ,illustration3 ,,fig4 #da4--;,inserting length of pipe4 ,while laying the pipe a stopper is used to prevent the sewer gases and foul odors from escaping4 ,this stopper sometimes is of tile1 sometimes a plug of paper or burlap4 ,this stopper is sometimes cemented in by inexperienced men and the trouble created can only be guessed at4 ,if a stopper is used1 the workman must see that it is taken out4 ,,refilling4--,after the pipe is laid and cemented1 it should be covered and allowed to stand #bd hours to give the cement time to harden4 ,the dirt should then be thrown in and settled by means of a tamper or by flooding with water4 ,the planks should not be taken out until the trench is well filled4 ,to pull the plank1 a chain or shoe and lever will have to be used4 ,where the tunnels are1 dirt will have to be rammed in with a long rammer1 care being taken not to disturb the pipe4 ,if the refill is not well rammed and tamped1 the trench will settle and cause a bad depression in the street surface4 ,,terra-,,cotta ,,pipe4--,terra-cotta pipe should be straight1 free from fire cracks1 and salt-glazed4 ,the inside of the hub and outside of the plain end should not be glazed4 ,this allows the cement to take hold4 ,,table ,,of ,,standard ,,terra-,,cotta ,,pipe ---------------------------------------- ------------------- ,size ,thickness1 ,weight per ft41 ,depth of ,annular space inches

---------------------------------------- ------------------- ,terra-cotta pipe should not be permitted in filled-in ground4 ,roots of trees find their way into the pipe through cracks or cement joints4 ,when the roots get inside of the pipe they grow until the pipe is stopped up4 ,as the roots cannot be forced or wired out1 the sewer must be relaid4 ,the writer has seen a solid mass of roots #aj feet long taken out of a tile sewer4 ,in case terra-cotta is laid in filled-in ground1 there is only one way to insure the pipe from breaking4 ,the pipe should be laid on planks4 ,then1 if the ground settles1 the pipe will not be broken4 ,,water ,,connection ,,and ,,service ,,tapping ,,main4--,the water service for a building is put in at the same time as the sewer is connected and run into the house4 ,for a #a-a_/d-service pipe a #a_/b-;inch tap is furnished4 ,the water company taps the main1 at the expense of the plumber1 and inserts a corporation cock4 ,illustration3 ,,fig4 #db4--,showing water main and sewer in same ditch4 ,,digging ,,trench4--,the trench for the water main should be dug at least #d-a_/b feet deep or below frost level and the trench should be kept straight4 ,when the sewer is put in at the same time1 one side of the sewer trench can be cut out after it is filled up to the level of the water main4 ,the water pipe can then be laid on this shelf at least #b feet away from the original trench of sewer4 ,sometimes the surface of the ground must not be disturbed4 ,in this case small holes are dug and the pipe is pushed through or driven through under that portion not dug4 ,these places are often tunnelled 7see ,fig4 #db74 ,in digging in city streets1 care should be taken not to destroy any of the numerous pipes encountered4 ,,laying ,,pipe ,the trench should be dug straight out from the house so the pipe can be laid and the main tapped straight out from the building4 ,the water companies keep a record of these taps so that in case of trouble the street can be opened and the water shut off4 ,in laying the water service1 the pipe from the curb to the main should be laid first4 ,this takes in all the pipe in the street4 ,at the main there is a shut-off in the tap4 ,another stop with ,t or wheel handle must be placed just inside the curb line4 ,this is called a curb cock 7see ,fig4 #dc74 ,one trench either outside or inside of the curb should be at least #ae feet long so that a full length of pipe can be laid in the trench4 ,it is generally impossible to open a trench the full length the pipe is to be run4 ,a trench #aj feet long is dug1 then #h feet left1 and another #aj- or #h-;foot trench is dug and the two are connected with a small tunnel and pipe pushed through4 ,when the pipe has been put in place between the curb and main1 the water is turned on and the pipe flushed out4 ,the valve at the curb should now be shut off1 and if there are any leaks they will show4 ,the street part is now ready to fill in4 ,at this point ,fig4 #dc should be studied4 ,note the piece of lead attached to the pipe and corporation cock4 ,this piece of lead should be extra heavy and always laid in place the shape of the letter ,s or goose neck4 ,in case the street should settle1 this piece of lead will allow for it4 ,these lead connections or goose necks are made as follows3 #c ft4 of #e_/h lead pipe2 #a-;inch brass solder nipple 7wiped on72 one brass corporation cock coupling 7wiped on74 ,,laying ,,pipe4--,this lead connection can be screwed on the pipe after the pipe is laid1 then bent and coupled on the main with the coupling4 ,illustration3 ,,fig4 #dc4--,water main from street to foundation wall4 ,after the pipe has been tested as far as the curb1 the trench in the street can be filled as described later4 ,the pipe from the curb to the building can now be laid4 ,if necessary to push the pipe through a tunnel1 the end of the pipe should first be capped4 ,start by screwing a length in the curb cock4 ,if the other end of the pipe comes in a tunnel an additional length must be put on before putting in place so that an end will come in the open trench4 ,when the building is reached and before the stop cock is put on1 the valve at the curb should be opened full and the pipe flushed out4 ,the valve can then be put on and water turned on to test the pipe4 ,,setting ,,curb ,,box4--,a cast-iron box1 adjustable length1 with cover should extend from the curb cock to the surface4 ,this makes it possible with a long rod to control the water service into the building4 ,to set a curb box some flat stones should be laid around the curb cock and the box set on these stones4 ,then the space around the box and pipe should be closed in with brick or other covering to keep the sand from washing in on the curb cock4 ,the box should be adjusted for height and then held in place by placing the curb key rod in place and holding the rod and box while the trench is filled4 ,the refill should be tamped evenly on all sides of the box4 ,,refill4--,in refilling the trench around the corporation cock and goose neck1 the greatest care should be taken4 ,the writer has seen cases when indifferent workmen have tossed heavy stones in the ditch and broken off the corporation cock or destroyed the goose neck4 ,after the pipe is covered with #ah inches of refill and tunnels have been filled1 water can be run in the trench and will settle the refill4 ,there are a number of special points concerning water services and taps at mains that should not be overlooked4 ,take for example a water service pipe which must be run through ground where electricity is escaping under trolley tracks1 around power houses1 etc4 ,the electricity will enter the pipe and wherever it leaves the pipe a hole is burned4 ,the surface of the pipe in a short time will be full of small pith marks and will soon leak4 ,a good way to add to the life of the pipe under these conditions is to make a star of copper and solder it on to the pipe in the street4 ,another piece of copper should be put on the pipe near the building4 ,the electricity will leave the pipe by way of the points on the star4 ,this method may not be a cure for electrolysis1 but will add to the life of the pipe4 ,another method employed is to put the pipe in the center of a square box1 then fill the box with hot pitch4 ,when this is hardened the pipe will have a covering that will keep out any moisture and bar electricity to a marked degree4 ,,materials ,,used4--,galvanized steel pipe does not last under ground4 ,galvanized iron1 heavy lead1 and brass are used4 ,wooden pipes were once used and stood years of service4 ,no service smaller than #a-a_/d should be used4 ,when the water service pipe passes through the foundation wall1 the pipe should not be built in1 but a small arch should be built over the pipe or a piece of ,,xx cast-iron pipe can be used as a sleeve 7,fig4 #dd74 ,illustration3 ,,fig4 #dd4--;,free space around pipe

,illustration3 ,,fig4 #de4--,sub-soil drain4 ,when a building is erected on a site that is wet or springy1 some means of carrying off the surplus water in the ground must be provided for1 or the basement of the building will be flooded with water4 ,for the thorough understanding of the methods employed in laying a drain of this kind1 ,i will go over it carefully and the beginner can read it and then study it1 and understand just how it is done4 ,a site may appear to be dry on the surface of the ground and yet be very wet under the surface4 ,if no information can be had regarding the site1 it is always well to drain the site if it is on a slope or near a body of water and on the water shed of a river or lake4 ,if a building is a large one and the foundation goes down very deep1 the site should always be drained4 ,the drain is laid under the basement floor and around the outside of the foundation wall on a level with or lower than the basement floor4 ,the value of draining a building site when the building is first started is very often overlooked4 ,the cost of the drain will be saved in a few years as the basement will be free from all excessive dampness4 ,the expense of installing a sub-soil after the building is up and in use is great as well as inconvenient4 ,the drain is called sub-soil drain on account of its location under the ground and on account of its duty of taking off all surplus water that is underground4 ,with the surface water taken off by the surface drains and the sub-soil drained by the sub-soil drains1 a wet building site can be made practically dry 7see ,fig4 #de74 ,,materials ,,used ,,in ,,sub-,,soil ,,construction4--,the object of the drain is to collect water and carry it away from the building by means of pipes4 ,terra-cotta pipes1 with or without hubs1 are used4 ,perforated tile pipe is sometimes used4 ,this pipe is unglazed terra-cotta pipe with #a-;inch holes in the sides about #c or #d inches from the center4 ,these holes allow the surplus water to enter the bore of the pipe and thus be carried off beyond the building site4 ,when the sub-soil of a small building needs draining1 the trenches made for the house drain and its branches are used as a drain in the following manner3 ,the trenches are dug deeper than is required for the house drain4 ,the trenches are then filled to the correct level with broken stones4 ,there is space between these stones for the water to find passage to a point away from the building4 ,when this method is employed1 some provision must be made to prevent the house drain from settling4 ,when locating the drain1 we must consider approximately the amount of water that is likely to be in the soil and required to be carried off4 ,if there is considerable water1 the pipes should extend all around the outside of the building foundation wall1 also a main pipe running under the cellar bottom with six branches1 three branches on each side4 ,if there is not a great deal of surplus water in the soil1 the drain around the outside of the foundation wall should be put in and one drain line running through the basement will be sufficient4 ,,laying ,,the ,,pipe4--,the drain pipe should be handled with care1 for it is easily broken4 ,the trench should be laid out and dug1 then the pipe can be laid in it with a grade toward the outlet or discharge4 ,if pipes with a hub on one end are used1 the hub should not be cemented4 ,a little oakum is packed in the hub to steady the pipe and keep sand out1 the bottom of joint is cemented1 a piece of tar paper can be laid over the top of the joint to keep the sand out4 ,with joints made this way1 the water can find its way to the bore of the pipe and yet the sand will be kept out of the pipe4 ,as soon as the water gets into the bore of the pipe it has a clear passageway to some discharge point away from the building4 ,if tile pipes without any hubs are used1 some covering should be put around the joint to keep out the sand and still allow the water to find its way into the pipes4 ,,discharge ,,of ,,sub-,,soil ,,drain4--,the water that accumulates in a sub-soil drain must be carried off to some point away from the building4 ,as the pipes are generally under the cellar bottom and under the house drain1 it is very evident that this drain cannot discharge into the house drain sewer1 directly4 ,if the building site is on a hill1 the drain can be carried out and discharged on the surface at a point that is somewhat lower than the level of the pipe under the building4 ,where this cannot be done1 it will be necessary to have the different lines of pipes discharge into a pit4 ,the water is accumulated in this pit until it is filled1 then it will automatically empty itself as later explained4 ,,pit ,,construction4--,the pit for the sub-soil water is constructed of cement4 ,a pit #b feet square or #b feet in diameter and #c feet deep will answer all requirements4 ,a pit of this depth will allow a pitch for all lines of pipe1 and is large enough for ordinary installations4 ,the pit is built up to the surface of the cemented floor of the basement and covered with a removable iron cover4 ,,cellar ,,drainer ,,or ,,pump4--,a cellar drainer is employed to empty the above-mentioned pit4 ,the cellar drainer works automatically4 ,when the pit is filled with water1 the drainer operates and empties the pit and discharges the water into a sink or open sewer connection4 ,when the pit is emptied1 the drainer shuts off4 ,the cellar drainer is operated by water pressure4 ,when the valve is opened1 a small jet of water is discharged into a larger pipe4 ,the velocity of this small jet of water creates a suction and carries along with it some of the water in the pit4 ,this suction continues until the tank is empty4 ,there should always be a strainer on the suction pipe1 also on the supply pipe1 to prevent any particles of dirt getting into the valve4 ,the pipes leading to and from the drainer should empty into an open sink where it can be seen4 ,there is a possibility of the drainer valve leaking and then the water pressure will leak through it1 causing a waste of water4 ,if this leakage can be seen where it discharges1 then the trouble can be rectified4 ,the cellar drainer is connected directly with the water pressure and should have a valve close to the connection to control the supply4 ,,chapter ,,ix ,,storm ,,and ,,sanitary ,,drainage ,,with ,,sewage ,,disposal ,,in ,,view ,the accompanying drawing of storm and sanitary drains should be studied in detail by the reader4 ,the location of each trap and fitting should be studied carefully and the reason that it is put in that particular place should be thoroughly understood4 ,below1 each plan has been taken and gone over in detail1 bringing out the reasons for fittings and traps1 also the arrangement of the piping4 ,illustration3 ,,fig4 #df4 ,the first thing to note in ,fig4 #df is the number and kinds of fixtures to be drained4 ,there is in the basement a set of three-part wash trays4 ,this will require a #b-;inch waste and a #a-a_/b-;inch vent4 ,there is in the drawing a #b-;inch waste extending to the fixtures above4 ,on the same line is a rain leader with a trap showing also a #d-;inch floor drain4 ,there are two #d-;inch rain leaders on the opposite corners of the plan1 in the rear of the building4 ,there is a #d-;inch soil stack for fixtures above and a #d-;inch soil stack in the basement on the same line for a basement toilet4 ,on the front there are rain leaders in each corner4 ,these will be connected outside of the house trap 7this feature should be noted74 ,the outlets that are to discharge into the house drain are as follows3 ,two #d-;inch rain leaders4 ,one #b-;inch sink waste4 ,one #b-;inch wash tray waste4 ,one #d-;inch floor drain4 ,one #d-;inch soil pipe4 ,one #d-;inch closet connection4 ,two #d-;inch front rain leaders to discharge into house sewer4 ,if we were to install this job1 we would first locate each pipe that enters the house drain4 ,the lowest outlet would be particularly noted1 in this case the #d-;inch floor drain4 ,from this drain we must make sure that at least #a_/d inch to the foot fall is secured4 ,we must then locate the house sewer where it enters the foundation wall1 then the work can be started4 ,i will not attempt to list the material that is necessary for this work1 at this time4 ,with all the material at hand the house drain is started4 ,all of this work is installed under the ground1 therefore trenches must be dug for all the piping4 ,the plumber must lay these trenches out and in doing so he must have in mind all connections and the fittings he can use so that the trenches can be dug at the right angle4 ,the trenches must be dug allowing a pitch for the pipe4 ,the height of the cellar is #h feet below the joists4 ,a stick is cut #h feet long which can be used to get the trenches below the cement floor at the right depth4 ,after the digging is completed1 the house trap1 which is a #f-;inch running trap1 is caulked into a length of #f-;inch cast-iron pipe4 ,this piece of pipe is pushed out toward the sewer bringing the trap near the foundation wall1 on the inside4 ,the fittings and traps and pipe are caulked in place as fast as possible4 ,when possible1 the joints are caulked outside of the trench in an upright position4 ,there are a number of different ways to caulk this pipe together1 and to make it clear to the beginner just how it is done the following exercise is suggested4 ,this job brings in the caulking of pipes1 traps1 and fittings in various positions4 ,two or three can work on this job together4 ,fig4 #dg shows how the pipe and fittings are put together1 which needs no further explanation4 ,therefore1 we will go over in detail only the caulking of the joints in the various positions4 ,illustration3 ,,fig4 #dg4 ,,material ,,needed4--,one length of #d-;inch extra heavy cast-iron pipe1 single hub2 two lengths of #d-;inch extra heavy cast-iron pipe1 double hub2 one running trap1 one full ,y1 one #d-;inch #a_/d bend2 two #d-;inch clean-out screws with iron body2 one

and pot4 ,the beginner should start at the trap and caulk the joints with the trap held in place4 ,the cold chisel should be sharp as it is used to cut the cast-iron pipe4 ,to caulk the straight end of cast-iron pipe into the hub end and make a water-tight joint when the pipe is in a vertical position1 the spigot end of the pipe is entered into the hub end of another piece4 ,a wad of oakum is taken and forced into the hub with the yarning iron4 ,this piece of oakum is forced to the bottom of the hub1 then another piece is put in4 ,the oakum is set and packed by using the yarning iron and hammer4 ,the hub is half filled with oakum4 ,the oakum is forced tight enough to make a water-tight joint4 ,if the oakum used comes in a bale1 pieces of it will have to be taken and rolled into long ropes about #ah inches long1 the thickness of the rope corresponding with the space between the hub and the pipe4 ,if rope oakum is used1 the strands of the rope can be used4 ,after the oakum is well packed into place and the pipe is lined up and made straight1 molten lead is poured in and the hub filled4 ,when the lead has cooled1 set the lead with the caulking tool and hammer1 making one blow on each side of the joint4 ,this sets the lead evenly on every side4 ,if there is any surplus lead1 it can now be cut off1 using the hammer and cold chisel4 ,the caulking iron is again taken and the lead next to the pipe is tamped1 striking the iron with the hammer at an angle to drive the lead against the pipe4 ,after this has been done all around1 the caulking iron is held in such a position that the lead around the hub will receive the force of the blow4 ,after this has been done1 the center of the lead is caulked and the joint should be tight4 ,with a little practice1 this can be done very rapidly4 ,the lead should be poured in while it is very hot4 ,the caulking must not be done by hitting heavy blows as there is a possibility of splitting the hub and thereby rendering the joint unfit for use4 ,,caulking ,,joint ,,in ,,horizontal ,,position4--,it is necessary in a great many cases to caulk a joint in a position where the lead would run out of the joint unless provision were made to hold it in4 ,to caulk a joint in a position of this kind1 the pipe is lined up and secured1 then the oakum is put in and forced to the bottom of the hub4 ,then a joint runner1 which is an asbestos rope about #b feet long and about #a inch in diameter1 is fitted around the pipe and forced against the hub where it is clamped by means of an attached clamp4 ,the clamp is put on the top of the pipe and so arranged that a channel will be left in a ,v shape4 ,this channel allows the hot lead to run between the asbestos runner and the hub4 ,when the lead has had a chance to cool1 the asbestos runner is taken off4 ,where the clamp was1 there will be a triangular piece of lead sticking out beyond the face of the hub4 ,this piece has to be cut off1 but no attempt should be made to do so until it has been caulked in place and well set2 also the rest of the lead should be set4 ,then the cold chisel can be used and this extra piece of lead taken off4 ,the caulking of the lead in this position is the same as in the previous position and should be carried out closely4 ,the beginner should understand that it is necessary to have not only the joints tight so that running water will not leak out of them1 but that the joints must stand a water test4 ,the testing of soil stacks is explained under another heading4 ,the lines of cast-iron pipe depend to a considerable extent upon these joints to make the whole line rigid4 ,,caulking ,,of ,,fittings4--,the caulking of fittings1 while done the same as a straight pipe1 is far more difficult4 ,the improper making of these joints is the cause of many leaks4 ,a long sweep fitting is caulked without a great deal of difficulty4 ,if a short bend fitting is used1 the matter of caulking is difficult4 ,the fitting is so short that it is almost impossible to get a caulking iron into the throat4 ,the mechanics will have to work at the throat from each side until this part has been sufficiently caulked4 ,i call attention to this point1 for ,i know it to be a failure in a large number of jobs when it comes to put the test on4 ,in order to caulk the fittings1 they must be put in their exact location and positions before the lead is poured in1 for after the lead is once in the fitting cannot be moved4 ,when there is a series of fittings on a line1 their positions in relation to each other must be considered before the lead is poured4 ,illustration3 ,,fig4 #dh4 ,illustration3 ,,fig4 #di4 ,illustration3 ,,fig4 #ej4 ,illustration3 ,,fig4 #ea4 ,fig4 #dh shows the same fixture and stack connections as ,fig4 #df4 ,two #d-;inch lines run through the cellar1 one a sanitary drain1 the other a storm drain4 ,each #d-;inch line has an intercepting trap4 ,on the sewer side of these traps the two lines are brought together1 beyond which point the two front rain leaders connect2 each of the two front leaders is trapped separately4 ,illustration3 ,,fig4 #eb4 ,fig4 #di differs from the preceding one in only two points4 ,first1 the two front leaders are brought into the cellar and connected into the storm drain on the house side of the intercepting trap4 ,second1 the storm and sanitary drains are connected on the outside of the building4 ,fig4 #ej shows the same fixtures collected into a #d-;inch house drain1 and the rain leaders run entirely on the outside of the building4 ,this plan is a good one as all the storm water is kept entirely outside the building4 ,if the storm drains are kept #e feet away from the cellar walls 7see ,plumbing ,code7 the pipes can be of tile4 ,another good feature of this plan is that all the pipes under the cellar are #d-;inch4 ,fig4 #ea is similar to ,fig4 #df1 the difference being in the location of the floor drain and the connection of the two rear rain leaders1 into the house drain4 ,in ,fig4 #eb the drains shown take the waste and storm water from the apartment building1 also a building set in the rear4 ,the leader pipes in this case are trapped on the outside of the wall4 ,the building in the rear you will note has a separate fresh air inlet and house trap1 and the house sewer is continued through the front house and connected into the house drain of the front building1 on the sewer side of the intercepting trap4 ,these drawings should be studied carefully and the student should in each case list correctly all of the material required for the installation of these jobs4 ,illustration3 ,,fig4 #ec4--;,cutting cast-iron pipe4 ,,cutting ,,cast-,,iron ,,pipe4--,to cut cast-iron pipe1 a sharp cold chisel and hammer are needed4 ,the pipe is marked all around1 just where it is to be cut4 ,then it is laid with the part of the pipe that is to be cut resting on a block of wood4 ,a groove is cut with the hammer and chisel around the pipe4 ,one person can turn the pipe while the other does the cutting4 ,after a little experience one man can cut and roll the pipe alone4 ,this groove is cut deeper and deeper until the pipe breaks apart4 ,if standard pipe is being cut1 a file is generally resorted to for cutting the groove4 ,on account of the lightness of the pipe1 a hammer and chisel will crack the pipe lengthwise4 ,when cutting extra heavy cast-iron pipe1 a good heavy blow must be struck to cause the chisel to cut into the iron4 ,after a few cuts1 the beginner will understand the weight of blow that must be struck to cut the pipe quickly4 ,,chapter ,x ,,soil ,,and ,,waste ,,pipes ,,and ,,vents4 ,,tests ,,soil ,,pipes ,the term soil pipes means pipe that receives the discharge from water closets4 ,the size of a soil pipe for ordinary dwellings should be #d inches4 ,,size ,,of ,,soil ,,pipes ,one to three closets--#d-;inch ,,xx cast-iron4 ,four to eight closets--#e-;inch ,,xx cast-iron4 ,eight to twelve closets--#f-;inch ,,xx cast-iron4 ,there are cases when #c-;inch ,,xx cast-iron pipe is used1 but the practice is not recommended4 ,the soil pipe should be well supported and held in place4 ,the connection between soil pipe and closet should be of lead to allow for any expansion of settling that might take place4 ,,material ,,of ,,soil ,,pipes4--,soil pipe in common use today is made of light cast iron1 tar-coated1 extra heavy cast iron uncoated and coated1 galvanized wrought-iron pipe1 and steel pipe4 ,the best kind to use depends upon the job and place where it is to be used4 ,all kinds of bends and fittings can be had in any of the above-mentioned materials4 ,in choosing the material of the pipe that is best to use1 the following points should be carefully considered4 ,first1 new work or overhauling4 ,second1 temporary or permanent job4 ,third1 construction of building4 ,fourth1 amount allowed for cost of materials on job4 ,fifth1 size of job1 that is1 the number of toilets4 ,sixth1 size of chases and pipe partitions4 ,,location ,,of ,,soil ,,pipe4--,the location of the soil pipe depends to a great extent upon the location of the toilets4 ,the soil stack should be located on an inside partition4 ,the horizontal pipe should not run over expensively decorated ceilings unless run inside of a trough made of copper or sheet lead4 ,as far as possible1 the pipes should be confined1 to runs short1 and the number of bends reduced4 ,,soil-,,pipe ,,fittings ,soil-pipe fittings can be had from stock almost to suit the conditions4 ,i will enumerate a few4 ,the names of these fittings should be familiar to the mechanic so that when ordering he can give the correct name4 #a_/af1 #a_/h1 #a_/f1 #a_/d bend1 sanitary tee1 tapped tee1 side outlet fitting1 return bend1 cross branches1 double ,y1 double ,,ty1 traps4 ,the uses of these cast-iron fittings perhaps are obvious1 but a word about the use of each one will be of service4 ,the #a_/d bend is used to change the direction of run of pipe #ij deg4 ,a long-sweep #a_/d bend is used on work requiring the best practice4 #a_/h1 #a_/af1 and #a_/f bends are used to change the direction of pipe #de deg41 #bb-a_/b deg41 and #af-b_/c deg4 ,two #a_/h bends should be used in preference to one #a_/d bend where there is sufficient room4 ,side outlet #a_/d bend is used for waste connection4 ,they can be had with an outlet on either side of the heel4 ,their use is not recommended4 ,return bends are used on fresh-air inlets4 ,tees are used for vents only4 ,ys are used wherever possible4 ,the use of a ,y-branch together with an #a_/h bend for a #ij deg4 connection with the main line is always preferable to a ,,ty or1 as they are commonly called1 sanitary ,t4 ,a tapped fitting gets its name because it is tapped for iron pipe thread4 ,tapped fittings are used for venting and should not be used for waste unless the tap enters the fitting at an angle of #de deg4 ,these fittings and pipe are joined by first caulking with oakum and pouring1 with one continuous pour1 the hub full of molten metal4 ,when cool1 the lead should be set and then caulked around the pipe and around the hub4 ,the amount of lead and oakum required for various-sized joints is as follows3 ,pipe size #b #c #d #e #f #h #aj #ab #ae ,pounds of lead #a-a_/b #b-a_/d #c #c-c_/d #d-a_/b #f #g-a_/b #i #aa-a_/d ,oakum 7ounce7 #d #f #h #aj #ab #af #bj #bd #cj ,,rust ,,joints4--,the plumber is called upon to run cast-iron pipe in places where lead and oakum will not be of service for the joints4 ,in cases of this kind1 a rust joint is made4 ,this rust is made according to the following formula3 #a part flour of sulphur4 #a part sal-ammoniac4 #ih parts iron borings 7free from grease74 ,this mixture is made the consistency of cement1 using water to mix thoroughly and bring all parts into contact with each other4 ,when it hardens1 it becomes very hard and makes a tight joint which overcomes the objections to lead and oakum joints4 ,,wrought-,,iron ,,and ,,steel ,,pipe ,this pipe comes in about #ah-;foot lengths and fittings of the following makes and shapes1 and their use is fully explained4 ,the lengths of pipe come with a thread on each end and a coupling screwed on one end4 ,the lengths come in bundles up to #a-a_/b-;inches and in single lengths over that size4 ,screw pipe fittings1 it will be noted1 are called by a different name than cast-iron ones4 ,the fittings in common use today are the #ij degree ell1 #de1 #bb1 and #af-b_/c4 ,the ,y and ,,ty1 tucker fittings1 and inverted ,ys are used in practically the same way as the cast-iron fittings4 ,the #ij degree ell1 #de1 #bb1 and #af-b_/c are used to change the run of pipe that many degrees4 ,all #ij degree fittings1 ells1 and ,ts are tapped to give the pipe a pitch of #a_/d inch to the foot4 ,it is better to use two #de ells to make a #ij bend when it is possible4 ,illustration3 ,,cast-,,iron ,,screw ,,fittings ,,fig4 #ed4 ,,inverted ,y4--,the inverted ,y is used in venting to good advantage4 ,the use of these fittings is illustrated in the sketches4 ,,waste ,,pipes4--,waste pipes are the pipes that run to or convey the discharge of waste matter to the house drain1 from wash trays1 baths1 lavatories1 sinks1 and showers4 ,the usual size of waste pipes is #b inches4 ,waste pipes are made of the same material as soil pipe4 ,lead and brass pipe are also in common use4 ,all exposed waste pipes in bath and toilet rooms are brass1 nickel-plated4 ,the waste pipes under kitchen sinks and wash trays are either lead or plain heavy brass4 ,all waste pipes are run with a pitch towards the house trap and should be properly vented as explained under venting4 ,the pipes should be easy of access1 with clean-outs in convenient places4 ,the waste pipes under a tile or cement floor should be covered with waterproof paper and a metal ,v-shaped shield over the entire length4 ,if the waste pipes are over a decorated ceiling they should be in a copper-lined or lead-lined box4 ,this box should have a tell-tale pipe running to the open cellar with the end of the tell-tale pipe left open4 ,if waste pipes are to take the discharge from sinks in which chemicals are thrown1 either chemical lead or terra-cotta pipe should be used4 ,if terra-cotta is used1 it should have at least #f inches reinforced concrete around it and the joints of pipe made of keisilgar4 ,,size ,,of ,,waste ,,pipes ,urinals #b inches ,kitchen sink #b inches ,slop sink #c inches ,receptacles #a-a_/b inches ,bath tubs #a-a_/b inches ,lavatories #a-a_/b or #a-a_/d inches ,wash trays #b inches ,,tell-,,tale ,,pipe4--,the tell-tale pipe is a small pipe that extends from the trough1 pan1 or box that is under a line of pipe or fixtures to the open cellar4 ,when water is seen running out of this pipe1 it shows that a leak exists somewhere in the line of pipe that is in the box or trough4 ,the use of this pipe saves the destruction of walls and ceilings4 ,,vents ,illustration3 ,,fig4 #ee4--;,circuit vent4 ,vents are the most important pipes in the plumbing system4 ,modern plumbing successfully attempts to make living in crowded and thickly populated districts1 as well as in isolated buildings1 free from all unpleasant odors and annoyances4 ,this could not be accomplished without the use of vents4 ,vents relieve all pressure in the system by furnishing an outlet for the air that is displaced by the waste discharged from the fixtures4 ,another of its functions is to supply air when syphonic action starts1 thereby stopping the action that would break the seal of the trap under fixtures4 ,the pipe extending from top fixture connection1 up to and through the roof1 is called the ventilation pipe4 ,all vents that do not pass directly through the roof terminate in this ventilation pipe4 ,to explain the use of vents1 we might well start in the basement of a dwelling house4 ,suppose there is a set of wash trays in the laundry2 the #b-;inch trap of these trays should have a #a-a_/d-;inch vent pipe leading from the crown of the trap up along side of the stack4 ,on the first floor a #a-a_/d-;inch pipe from the crown of the kitchen sink trap will lead into it4 ,here the pipe should be increased to #b inches4 ,on the second floor the #a-a_/d-;inch pipes leading from the lavatory and bath traps come into it4 ,the vent stack now extends up into the attic and connects with the ventilation pipe4 ,in a general way1 the above is an example of venting4 ,the old method of venting was very complicated and is almost beyond describing with the pen4 ,illustration3 ,,fig4 #ef4--,loop vent4 ,in common use today1 there are several kinds of venting1 namely3 circuit and loop venting1 crown venting1 and continuous venting4 ,the circuit venting1 ,fig4 #ee1 is used in connection with the installation of closets4 ,take a row of toilets in which the waste connection of each closet discharges into a ,y-branch1 and there will be a series of ,y-branches4 ,one end of this series of branches discharges into the main stack while the other end continues and turns up at least to the height of the top of the closet and then enters the main vent stack4 ,when this main vent runs up along side of the main stack and forces the vent pipe connected to the series of ,y-branches to travel back1 it is called a loop vent4 ,this type of vent supplies air to the complete line of toilets and is very efficient4 ,illustration3 ,,fig4 #eg4--;,continuous vent4 ,illustration3 ,,fig4 #eh4 ,,continuous ,,venting1 ,figs4 #eg and #eh1 applies more to fixtures other than toilets4 ,a ,p-trap is used and enters a ,t in the stack4 ,the lower part of the ,t acts as and connects with the waste pipe while the upper half is and connects with the vent pipe4 ,a study of the figures will aid the reader to understand thoroughly the above explanations4 ,in continuous venting the waste of the lowest fixture is discharged into the vent pipe and extended to the main waste stack where it is connected4 ,this is done to allow any rust scales that occasionally drop down the vent pipe1 and render it unfit to perform its duty1 to be washed away into the sewer4 ,,crown ,,venting1 ,fig4 #ei1 is as its name implies1 a vent that is taken from the crown of the trap1 thence into the main vent4 ,each one of these methods of venting is used and considered good practice1 provided it is properly installed and correctly connected with the use of proper fittings4 ,illustration3 ,,fig4 #ei4--;,crown venting4 ,,things ,,to ,,remember4-- ,first1 venting is to prevent traps from syphoning4 ,second1 also to allow free passage of air4 ,third1 circuit vent--loop vent4 ,fourth1 continuous venting4 ,fifth1 crown venting4 ,sixth1 ventilation pipe extends from the top of fixture through roof4 ,,chapter ,,xi ,,house ,,traps1 ,,fresh-,,air ,,connections1 ,,drum ,,traps1 ,,and ,,non-,,syphoning ,,traps ,the house trap is a deep seal trap placed inside the foundation wall1 and intersects the house drain and house sewer4 ,the trap is placed at this point for a number of reasons3 first1 to keep sewer gases from entering the pipes in the house2 second1 this location is where the house drain ends4 ,this trap should have two clean-outs1 one on each side of the seal4 ,the clean-outs should be of extra heavy cast-iron body with a heavy brass screw cap4 ,the cap should have a square nut for a wrench to tighten or unscrew the cap4 ,this cap should be brought up flush with the floor4 ,when a house trap is being set1 it is necessary to set it perfectly level1 otherwise the seal of the trap is weakened and sewer gases can enter4 ,sometimes the trap is located on the house sewer just outside of the foundation wall4 ,in this case1 a pit should be built large enough for a workman to get down to it to clean it out when necessary4 ,a mason's trap was formerly used to a considerable extent1 but is very poor practice to use today on modern work4 ,this trap was built square of brick with a center partition4 ,the brick soon became foul and the trap would be better termed a small cesspool than a trap4 ,,points ,,to ,,remember ,,about ,,house ,,traps4-- ,first1 should be a running trap4 ,second1 two clean-outs4 ,third1 deep seal1 at least #b inches4 ,fourth1 set level4 ,fifth1 set inside foundation wall4 ,sixth1 accessible at all times4 ,seventh1 same size as house drain4 ,eighth1 fresh air should connect with it4 ,,fresh-,,air ,,connections ,the term fresh-air inlet is1 as its name implies1 an inlet for fresh air4 ,it is placed directly on the house side of the main trap4 ,the connections made vary considerably4 ,a few good connections in common use are explained below4 ,when the trap is in place1 one of the clean-outs can be used for the fresh air4 ,if this is done1 a ,y-branch should be placed in the hub of the clean-out4 ,the ,y-branch should be used for the fresh air and the run should be used for a clean-out4 ,a ,y-fitting can be inserted directly back of the trap and the branch used for the fresh air4 ,an inverted ,y makes a good fitting to use directly back of the trap4 ,these branches should be taken off the top of the pipe4 ,the branch taken off for the fresh-air inlet should not have any waste discharge into it and should not be used for a drain pipe of any description4 ,the fresh-air inlet should run as directly as possible into the outer air1 at least #ae feet from any window4 ,the pipes terminate in a number of different ways1 some with a return bend1 above the ground1 some with a cowl cap1 some with a strainer4 ,when necessary to run pipe through the sidewalk1 a box of brick is made with a heavy brass strainer fitted level with the sidewalk into which the pipe runs4 ,if the pipe is run into the box on the side a little up from the bottom1 the possibility of becoming stopped up or filled up is not great4 ,the fresh-air inlet sometimes terminates above the roof of the building4 ,special care should be given this fresh-air inlet as it supplies fresh air to the entire system and thus keeps the pipes in a much better sanitary condition4 ,sometimes when the house drain is full of sewage1 air is pushed out of the fresh-air inlet and disagreeable odors are evident4 ,this is why it should be located as far as possible from any window4 ,special care should be taken on the part of the plumber not to locate the fresh-air inlet nearer than #ae feet to the fresh-air intake of the heating system4 ,illustration3 ,,fig4 #fj4--;,fresh-air inlet4 ,when the pipe passes through the foundation wall1 the same care should be exercised as with other pipes4 ,that is1 if the pipe is #d inches1 a sleeve #f inches should be cut in the wall for the #d-;inch pipe to pass through4 ,,points ,,to ,,remember ,,about ,,fresh ,,air4-- ,first1 never should be smaller than #d inches4 ,second1 one size smaller than trap4 ,third1 location1 directly back of trap4 ,fourth1 leads to outer air4 ,fifth1 keep away from windows and intake of heating system4 ,sixth1 always have end of pipe covered with strainer1 cowl1 or return bend4 ,seventh1 make as few bends as possible4 ,eighth1 supplies fresh air to system4 ,,drum ,,trap ,the use of the drum trap is very handy to the plumber as well as efficient and practicable when installed4 ,the trap can be purchased without any outlets or inlets1 so the plumber can put them in according to the necessary measurements4 ,the making of these traps with lead is explained in the chapter on ,wiping ,joints4 ,the open end has a brass clean-out screw on it4 ,when this clean-out screw comes below the floor1 another brass screw cap and flange is screwed on the floor above the trap so that the clean-out screw in the trap is easily accessible4 ,illustration3 ,,fig4 #fa4--;,drum trap4 ,these drum traps are called bath traps as they are used mostly on bath wastes4 ,they should never be installed with the clean-out exposed to the sewer side of the trap4 ,in the best practice1 heavy brass drum traps are used4 ,,non-,,syphoning ,,trap ,illustration3 ,,fig4 #fb4--;,flask trap4 ,illustration3 ,,fig4 #fc4--;,clean-sweep trap4 ,after years of experimenting to produce a trap that would not syphon without venting1 we find in use today a large variety of non-syphoning traps4 ,traps that will hold their seal against all practical forms of syphonic action1 or other threatening features1 have been made and used and serve the purpose for which they are intended4 ,various means to prevent the breaking of the seal of these traps are employed4 ,while some depend on a ball or other kind of valve1 others rely on partitions and deflections of various kinds4 ,all of these perform the functions for which they are designed1 yet the devices employed offer an excellent obstruction for the free passage of waste2 therefore1 in time1 these traps become inoperative4 ,it should be borne in mind that any traps with a mechanical seal or an inside partition are not considered sanitary4 ,the inside partition might wear out or be destroyed and thus break the seal without the knowledge of anyone and allow sewer gas to enter the room4 ,the mechanical device may also be displaced or destroyed1 leaving the trap without a seal4 ,if the trap were cleaned out often or examined occasionally1 these traps could be used with a greater degree of safety4 ,some of the forms of non-syphon traps in common use are3 ,the ,flask ,trap1 ,fig4 #fb4 ,this trap gets its name from its shape4 ,there is an inside wall upon which the seal depends4 ,this trap is like the bag trap1 only the two inside walls of the pipe are combined into one4 ,this wall should be of heavy cast brass1 free from sand holes4 ,clean ,sweep ,trap1 ,fig4 #fc4 ,some clean sweep traps are dependent upon an inside wall for their seals4 ,they are made of #a_/b-,s1 #c_/d-,s1 and full ,s4 ,illustration3 ,,fig4 #fd4--,mechanical-seal trap4 ,illustration3 ,,fig4 #fe4--,standard ,s trap4 ,illustration3 ,,fig4 #ff4--;,bag trap4 ,sure ,seal ,trap4 ,the sure seal trap is designed to be non-syphoning4 ,this trap also has an interior waterway4 ,if this waterway leaks1 the trap is unfit for use4 ,if these traps are made as shown in the second sketch with the way inside of a larger pipe1 it can be detected if the interior wall leaks4 ,centrifugal ,trap4 ,the centrifugal trap is made similar to the clean sweep1 except that the wall of the inlet pipe is entirely separate from the body of the trap4 ,the inlet enters the body of the trap on a tangent1 thus making the trap self-scouring which is a good feature4 ,,chapter ,,xii ,,pipe ,,threading ,the proper cutting of threads on pipe is overlooked by some mechanics4 ,there are many different kinds of dies and different kinds of pipe to contend with4 ,steel pipe threads very hard and the adjustable dies should be used on it4 ,these dies cut more easily and leave a cleaner thread than other dies when used on steel pipe4 ,when threads are cut on wrought-iron pipe the adjustable dies should be used as they cut a better and cleaner thread than other dies4 ,to preserve the life of the dies and the quality of the thread1 oil is used freely while the dies are cutting4 ,,threads4--,the standard thread on pipe and fittings is a right-handed thread4 ,left threads can be cut on the pipe and the fitting can be tapped with a left thread4 ,when a fitting is tapped with a left thread it is marked so4 ,the following table gives the standard number of threads that a die will or should be allowed to cut on the pipe3 ---------------------------------------- ------------------- ,size ,length1 inches ,threads per inch ,threads per end ---------------------------------------- ------------------- #c_/h #i_/af #ah #aj4hbe #a_/b #c_/d #ad #aj4ejj #c_/d #c_/d

the beginner with iron pipe work1 the following exercise is given4 ,in it there are a great many of the actual problems that come up when the pipe is put in on a job4 ,this is the last exercise that is required in this book4 ,the sketch shows clearly just what the job is and below ,i have gone over each operation that is necessary to complete the job4 ,illustration3 ,,fig4 #fg4 ,,materials ,,necessary4--,six feet of #a-;inch black pipe2 four #a-;inch black ells2 two #a-;inch tee2 one #a-;inch right and left coupling2 oil4 ,,tools ,,necessary4--,two #ad-;inch pipe wrenches1 vise1 pipe cutters1 stock and #a-;inch follower right and left die and reamer4 ,the vise is made secure on a bench or post1 care being taken before it is put in place to provide room enough to swing the stocks4 ,a length of #a-;inch pipe is put into the vise and the vise clamped around it4 ,the end of the pipe that is to be threaded should stick out through the vise about #i inches4 ,if there is a thread on this end1 the dies should be run over it to make sure that it is a standard thread and to clean the threads4 ,before proceeding further with this exercise the dies and stocks will be described and their use shown4 ,,dies4--,a full set of dies is taken4 ,the full set of stocks and dies is composed of right and left dies from #a_/h inch up to #a inch1 with a guide for each size1 also a small wrench with which to turn the set screws4 ,the dies come in sets1 two in a set4 ,these are the ,armstrong patent that ,i am describing4 ,take the stock and the handles1 and a set of #a-;inch right dies with the guides out of the box4 ,the dies will have marked on them #a ,r 7if #a-;inch left were wanted1 the mark would be #a ,l74 ,the set screws are taken out of the stock and the dies inserted in their proper place4 ,there is a deep mark on the edge of each die and under it a letter ,s4 ,this letter means standard4 ,this mark on the die is set even with a similar mark on the stock and when the set screws are in place and tightened1 a standard thread will be cut4 ,there is an adjusting screw on the stock to make the proper adjustment on the dies4 ,,stock4--,the stock is taken and the handles are put into it4 ,there are two sets of set screws on the stock1 one set for holding the dies in place and the other set for adjusting the dies4 ,on the stock there is a deep mark to correspond with the standard thread mark on the dies4 ,on the opposite side of the stock there is a place for the follower and a set screw to hold it in place4 ,after the stocks have been looked over and examined thoroughly1 the #a-;inch right dies are taken and inserted4 ,then the #a-;inch follower is put in place4 ,the tool is now ready to cut a #a-;inch thread4 ,now take a piece of #a-;inch pipe at least #ae inches long and put it in the vise1 letting it extend out from the vise about #i inches4 ,the stock is now taken and the follower end is put on the pipe first and the dies brought up in place to cut4 ,the end of the pipe is allowed to enter in between the two dies so that the teeth of each die rest on the pipe4 ,now1 holding the handles of the stock about #f inches from the body of the stock and standing directly in front of the pipe1 push and turn to the right at the same time and the dies will be started4 ,now put some oil on the dies and turn the stock1 taking hold of the ends of the handles and standing at one side4 ,the dies are run up on the pipe until the pipe extends through the face of the dies one thread4 ,oil is put on the pipe and the dies at least twice during the cutting4 ,when the thread is long enough the stock is turned back a little and then forward a little and the loose chips are blown out from between the dies and pipe4 ,if the dies are set right1 a good clean standard thread will have been cut4 ,this thread can now be cut off with the pipe cutters4 ,,pipe ,,cutters4--,to cut pipe with a one-wheel pipe cutter is a simple matter4 ,i will not dwell at length on the cutter itself4 ,there are one-wheel and three-wheel cutters4 ,we will use a one-wheel cutter tool4 ,this cutter is forced into the surface of the pipe with a set screw having a long tee handle4 ,the pressure that is brought to bear on the pipe while being cut is sufficient to cause a large burr to form on the inside of the pipe4 ,sometimes the pipe is completely crushed and rendered unfit for use4 ,therefore the user of these cutters should exercise care when cutting pipe4 ,the pipe is put in the vise and the cutters are so put on the pipe that the pipe will be between the two rollers and the cutter wheel1 the cutter resting on the mark that indicates the point at which the pipe is to be cut4 ,the handle is screwed down and the cutters turned around the pipe2 each time the cutters make a complete turn the handle is screwed down more4 ,this procedure is continued until the furrow has been cut clear through the pipe4 ,,cutting ,,and ,,threading ,,nipples4--,nipples are short pieces of pipe threaded on each end4 ,pieces of pipe longer than #f inches are not called nipples4 ,when a nipple is so short that the threads cut on each end meet in the center of the piece1 the nipple is called a close nipple4 ,when there is a space of about #a_/d inch between the threads1 it is called a space or shoulder nipple4 ,to cut and thread these nipples a nipple chuck or nipple holder is necessary4 ,illustration3 ,,fig4 #fh4--,nipple chuck and nipples4 ,,nipple ,,holders4--,take a piece of #a-;inch pipe about #ab inches long and on one end cut a thread that is #b inches long4 ,take a #a-;inch coupling and screw it on this end until the end of the pipe is almost through the end of the coupling4 ,at least four threads should be allowed at this end of the coupling4 ,now we have a piece of pipe #ab inches long having a thread #b inches long on one end with a coupling on the thread4 ,this is called a nipple holder4 ,now1 to cut a nipple1 cut a thread on a piece of pipe and cut the pipe off at any desired length1 say #b inches4 ,put the nipple holder in the vise with the coupling out from the vise about #h inches4 ,take the #b-;inch piece of pipe with a thread on one end1 screw this thread into the coupling until it touches the pipe that has been screwed through from the other end4 ,now the stocks having the #a dies and the follower in are put on the pipe4 ,the follower will not go over the coupling1 therefore take the follower out of the stock4 ,now the stock will slip over the coupling and the thread can be cut4 ,with this procedure a nipple of any length can be cut4 ,there are a number of patented nipple chucks on the market1 but as they are not always at hand the above method is resorted to and serves every purpose4 ,,long ,,screws4--,to cut a long screw which comes in use frequently on vent pipe work1 a piece of pipe #ab inches long is taken and a regular length thread is cut on one end1 and a thread #d inches long is cut on the other end4 ,then a coupling is cut while screwed on a pipe1 so that a lock nut about #a_/b inch wide is made4 ,the description and use of these long screws will come under screw pipe venting4 ,now that the proper use of the tools has been explained1 we will proceed with the exercise according to the sketch4 ,with a length of pipe in the vise and the #a-;inch dies in the stock1 run over the thread on the pipe4 ,note that all the measurements are center to center4 ,screw an elbow on the pipe and measure off the first length1 which we will take as #ab inches center to center4 ,place the rule on the pipe with one end of it at the center of the opening of the elbow just screwed on4 ,mark #ab inches off on the pipe4 ,this mark represents the center of another ell4 ,now take another ell and hold the center of one outlet on this mark4 ,it will readily be seen that to have the measurement come right1 the pipe must be cut off at a point where it will make up tight when screwed into the ell4 ,therefore1 about #a inch will have to be cut off1 making the pipe #a inch shorter than where it was first marked4 ,cut the pipe1 and before taking it out of the vise make a thread on the pipe still in the vise4 ,after the thread is cut1 take the reamer and ream out the burr that is on the inside of the pipe caused by the pipe cutter4 ,an elbow can be screwed on this pipe4 ,the next measurement is marked off as explained1 the pipe cut1 then the piece in the vise threaded and reamed4 ,the measurements must be accurate and the dies should be adjusted to cut all threads the same depth4 ,when the measurements are all out1 there should be seven pieces of pipe1 each piece having one thread4 ,now the threads on the other end can be cut except the #ab inch piece that screws into the right and left coupling4 ,this thread is a left-handed thread and must be cut with the left dies4 ,change the dies now to the #a-;inch left dies2 turn the stock in the opposite direction of the right-hand thread1 and the dies will cut the left thread4 ,the pipe and the fittings can easily be put together as shown in the sketch by following the center to center measurements4 ,the right and left coupling is the only fitting that will cause the beginner trouble4 ,a right and left coupling can be used only when there is sufficient give to the pipe1 that is1 the two ends of the pipe to be coupled together are only #a_/b inch apart4 ,to get the coupling in place to start the threads1 the pipe must spread apart at least #b inches4 ,if the pipe cannot be spread that much1 a right and left coupling cannot be used4 ,the proper way to make up a right and left coupling is as follows3 ,illustration3 ,,fig4 #fi4--;,f reads center of ell to end1 ,c reads center of ell to center of valve1 ,d reads center of valve to center of ,t1 ,e reads center of ,t to center of ell4 ,screw home the coupling on the right thread4 ,mark with a piece of chalk on the coupling and the pipe showing a point on each where the coupling makes tight4 ,take off the coupling and count the turns and make note of the number4 ,now do the same on the left thread and make a note of the number of threads4 ,if the left thread has six turns and the right has four and one-half1 then to insure that the left thread will be tight when the right thread is1 the coupling must be put on the left thread one and one-half turns before it is started on the right thread4 ,now with four and one-half turns1 the right and the left threads will both be tight4 ,a little thought and practice will make this connection clear4 ,if all the measurements in this exercise are not cut accurately1 the right and left coupling will not go together4 ,,chapter ,,xiii ,,cold-,,water ,,supply4 ,,test ,the supplying of cold water to buildings and then piping it to the various fixtures makes a very interesting study4 ,we have gone over the methods of laying and piping for the house service pipe4 ,we will go over the different systems now employed to supply the water1 quickly4 ,,underground ,,water4--,in thinly populated districts the well is still employed to supply water to the building4 ,the water is brought to the surface by means of a large bucket or by means of a pump4 ,a well point can be driven into the ground until water is reached and then the water can be brought to the surface by means of a pump operated by hand or by power4 ,the water can be forced to a tank that is open and elevated1 or forced into a tank that is closed and put under pressure4 ,from either tank the water will flow to any desired outlets4 ,a windmill can be employed to furnish power to operate the pump4 ,water supply that is received directly from underground is by far the best to use4 ,a cesspool or outhouse must not be allowed on the premises with a well1 otherwise the well will be contaminated and unfit for domestic use4 ,an open well is not as sanitary as a driven well1 as the surface water and leaves1 etc41 get into it and decay and pollute the water1 and soon make it unfit for domestic use4 ,,streams ,,and ,,brooks4--,the brooks and streams furnish a good source of supply for water to a building or community of buildings4 ,the writer recently worked on a system of piping that supplied #ae or #bj buildings4 ,the water supply came from a brook that was higher than the houses4 ,each house had a separate pipe leading down from the brook into a tank from which the house was piped4 ,the owner of the brook applied business ethics to the privileges of taking water from it4 ,he had a scale of prices1 and the highest-priced location was an inch or so below the bed of the brook1 the next price was level with the bottom1 the next cheaper #b inches above the bottom4 ,as the surface was reached1 the privilege cost less4 ,in the dry time of the year those at the bottom of the brook always had water while those at the top location had to wait for the water to rise1 and had to do without water during the dry time4 ,where the stream is on a lower level than the building a hydraulic ram can be used4 ,,rivers ,,and ,,lakes4--,rivers and lakes make an abundant supply for water systems4 ,a sluggish-moving river is bad1 also a river that is used for carrying off the sewage of a town4 ,special provision is now made for the using of water that is polluted4 ,a lake that is supplied by springs is by far the best source of supply4 ,the water is pumped from the river or lake into a reservoir and then flows by gravity into mains and from the mains into the buildings4 ,the water should always be filtered before it is allowed to enter the distributing mains4 ,,water ,,pressure4--,pressure at a fixture or outlet so that the water will flow is generally obtained by the force of gravity4 ,when this method is not sufficient1 a pneumatic system is employed4 ,this method is employed to force the water to the top floors or to supply the whole building in high structures4 ,the pneumatic system requires a pump1 an air-tight tank1 and pipes to the various outlets4 ,the water pumped into the air-tight tank will occupy part of the space generally occupied by the air4 ,the air cannot escape and is1 therefore1 compressed4 ,continued pumping will compress the air until the limit of the apparatus is reached4 ,if a valve or faucet that is connected with the tank is opened1 the air will expand and force the water out of the opening4 ,this explains in a general way the operation of a pneumatic water-supply system4 ,water can be pumped into this air-tight tank from a well1 cistern1 river1 lake1 or from the city supply mains4 ,illustration3 ,,fig4 #gj4--;,banjo4 ,,piping4--,from the service pipe on which there has been placed a shut-off1 a line of piping1 full size1 is run through the basement1 overhead to a convenient place1 perhaps to a partition in the center of the cellar4 ,the pipe is brought down and connected into the end of a header4 ,this header or banjo is made of ,ts placed #d inches center to center4 ,from each ,t a line of pipe is run to each isolated fixture or set of fixtures 7see ,fig4 #gj74 ,a stop and waste cock is placed on each line at such a point that all stop cocks will come in a row near the header4 ,a small pipe is run from the waste of each stop and discharged into a larger pipe which connects with a sink4 ,this way of running pipes while it is expensive makes a very neat and good job4 ,each stop cock has a tag on it stating explicitly what it controls4 ,if the building is a large one a number of these panelled headers are used4 ,a less expensive way to run this pipe is to branch off from the main at points where the branch pipe will be as short as possible and use as few fittings as possible4 ,stop and waste cocks are then placed on each branch near the main4 ,all pipe must follow the direct line of fitting with which it is connected4 ,the line of pipe should be perfectly straight4 ,if it seems necessary to bend the pipe to get around an obstacle1 then good judgment has not been used in placing the fitting into which the pipe is screwed4 ,the fitting should be re-located so that the pipe can be run without bending4 ,to have true alignment of pipes the whole job or section of the job must be drawn out on paper first and any obstacles noted and avoided before the piping is cut4 ,this not only saves time but it is also the forerunner of a good job4 ,when getting measurements for piping the same rule or tape should be used to get out the pipe as was used to get the measurements4 ,the water main and branches that run through the basement of a building are generally hung on the ceiling4 ,rough hangers of wood1 rope1 or wire are usually used to hold the pipe in place at first1 then neat and strong adjustable hangers are placed every #h feet apart4 ,there are in use too many kinds of hangers to explain or describe them here4 ,the essential point of all good hangers is to have them strong1 neat1 and so made that perfect alignment of the pipe can be had4 ,the hangers should be so placed that no strain will come on the fitting or the valves4 ,a hanger should be placed near each side of unions so that when the union is taken apart neither side of the pipe will drop and bend4 ,hooks and straps should be used to hold vertical pipes rigid and in position4 ,a vertical pipe should be so held in place that its weight will come on the hooks and straps that hold it rather than on the horizontal pipe into which it connects4 ,where there are six or eight horizontal lines of pipes close together1 a separate hanger for each pipe makes a rather cumbersome job and it consumes considerable time to install them properly4 ,a hanger having one support run under all the pipes will allow space for proper alignment and adjustment for drainage4 ,allowance must be made on all lines of pipe for drainage4 ,when a building is vacant during cold weather1 the water is drawn off2 therefore1 the pipes should have a pitch to certain points where the pipes can be opened and the entire system drained of water4 ,,kinds ,,of ,,pipe4--,the kind of pipe that is used for cold-water supply depends on and varies according to the kind of water1 the kind of earth through which it runs1 and the construction of the building4 ,wrought iron1 steel1 lead1 brass1 tin-lined brass1 are in use4 ,the supply pipe to every fixture should have a stop on it directly under the fixture4 ,this will allow the water to be shut off for repairs to the faucet without stopping the supply of other fixtures4 ,the making of perfect threads on pipe is an important matter1 especially on water pipes4 ,if the pipe and the dies were perfect1 and the mechanic used sufficient oil in cutting1 and the fittings were perfectly tapped to correspond to the dies used on the pipe1 of course a perfect union between pipe and fitting would result and the joint would be found to be perfect on screwing the pipe home4 ,as all the above conditions are not found on the job1 threads are made tight by the use of red or white lead and oil4 ,the lead is put on the thread and when the thread is made up the lead will have been forced into any imperfection that may be in the threads and the joint will then be water-tight4 ,white lead and oil should be used on nickel-plated pipe as other pipe compounds are too conspicuous and look badly4 ,a pipe compound should be used with discretion1 for if too much is put on a burr of it will collect in the bore of the pipe and reduce it considerably4 ,this is not tolerated1 so only a small amount is used4 ,water pipes should be run in accessible places1 making it possible to get at them in case of trouble4 ,in climates that have freezing weather water pipes should not be run in outside partitions4 ,if it is found absolutely necessary to do so1 as in the case of buildings which have no inside partitions on the first floor1 the pipe should be properly covered and protected4 ,the different methods of covering pipes are described in ,chapter ,,xv4 ,,chapter ,,xiv ,,hot-,,water ,,heaters4 ,,instantaneous ,,coil ,,and ,,storage ,,tanks4 ,,return ,,circulation1 ,,hot-,,water ,,lines ,,and ,,expansion ,the problem of supplying hot water to plumbing fixtures is one that has required years of study4 ,each job today demands considerable thought to make it a perfect and satisfactory hot-water system4 ,we will find installations today where the water is red from rust1 where there is water pounding and cracking4 ,there are also jobs where the fixtures get practically no hot water4 ,as each job or individual building has its own peculiar conditions1 they must be solved by the designer or the mechanic1 using the fundamental principles of hot-water circulation4 ,we must first know how much hot water is to be used1 also the location of the outlets and the construction of the building2 then the size of the pipes and the size of the tanks and their locations can be settled4 ,if the job is a large one1 a pump may be employed to insure the proper circulation4 ,after this the pipe sizes and connections can be worked out4 ,the one great enemy of hot-water circulation is air4 ,therefore1 no traps or air pockets should ever appear in the piping system4 ,the boiler1 as it is often referred to1 is the hot-water storage tank4 ,a copper or iron tank holding sufficient water to supply all fixtures1 even when every fixture demands a supply at the same time1 is installed in a convenient place and the heating arrangement connected with it4 ,a thermostat can be placed on the system and the temperature of the water controlled4 ,according to the size of the building the problem of furnishing the plumbing fixtures with hot water increases4 ,,methods ,,of ,,heating ,,hot ,,water4--,there are a number of ways of furnishing hot water4 ,some of the installations are listed below4 ,a cast-iron or brass water back is placed on the fire pot of a stove or furnace4 ,a separate stove with the fire pot and water jacket is used4 ,a coil of steam pipe is placed inside a hot-water boiler or tank4 ,gas coil heaters are connected with hot water storage tank1 also gas coil instantaneous heaters are connected with the piping direct4 ,combinations of the above systems are in use and serve the purpose for which they are intended4 ,for instance1 the tank can be connected with a coal range and a gas coil heater1 heat being furnished by the range alone or the coil heater alone1 or both can be used at the same time4 ,this combination can be connected with the furnace in the cellar1 and during the winter months1 when the furnace is in use1 the water can be heated by the furnace coil4 ,in warm weather1 when the furnace is out1 the range can supply the necessary heat4 ,in hot weather the coil gas heater can supply the heat4 ,,connections ,,of ,,tank ,,and ,,heating ,,apparatus4--,the ordinary house boiler or hot-water storage tank has four connections1 two on top1 one on the side1 and one on the bottom4 ,the top connections are used for the entrance of cold water into the tank and for the supply of hot water to the fixtures 7see ,fig4 #ga74 ,the cold-water inlet has a tube extending into the tank below the side connection4 ,this tube has a small hole filed in it about #f inches from the top4 ,this hole is to break any syphonic action that may occur at any time4 ,the side connection is for the connection of the pipe coming from the top of the water back4 ,the bottom opening in the tank is for the connection of the pipe coming from the lower water back connection1 also for draining the boiler4 ,the circulation of the water can be followed thus3 cold water enters the boiler in the tube and discharges into the boiler below the side connection4 ,from here it flows out of the bottom connection into the water back1 through the upper connection into the boiler1 through the side opening1 then to the top of the boiler and out to the fixtures through the fixture supply opening4 ,illustration3 ,,fig4 #ga4--,storage tank1 and coil heater with thermostatic control valve4 ,fig4 #fi shows a thermostatic control valve attached to the bottom of a heater coil1 and at the side of storage tank4 ,the best arrangement is at the bottom1 for it does not shut off the gas supply until the boiler is full of hot water4 ,,connecting ,,tank ,,and ,,coil ,,gas ,,heater4--,the boiler and the coil gas heater have a different connection4 ,the bottom of the tank and the bottom of the heater are connected4 ,the top of the heater and the top of the boiler are connected4 ,the accompanying sketch shows how this connection is made4 ,if the tee on the top of the boiler into which the gas-heater connection is made is not the first fitting and placed as close to the outlet as possible1 the water will not circulate freely into the boiler4 ,this connection according to the drawing should be studied and memorized4 ,illustration3 ,,fig4 #gb4--;,instantaneous gas heater4 ,showing circulation heater or booster4 ,,instantaneous ,,gas-,,heater ,,connections4--,an instantaneous gas heater is placed in the basement4 ,the copper coil in it is connected at the bottom with the cold-water supply and the top outlet of the coil is connected with the hot-water system of piping4 ,there is no need of a storage tank with this heater4 ,when a faucet is opened in any part of the hot-water piping system1 the water passing through the water valve at the heater causes the gas valve to open so that the whole set of burners in the heater is supplied with gas1 and the burners are lighted from a pilot light4 ,when the faucet is closed1 the gas supply is shut off and the burners are put out4 ,the pilot is lighted all the time4 ,space will not permit going over these connections in detail4 ,it is a large field and requires considerable thought4 ,,safety ,,and ,,check ,,valves4--,when a meter is used on a water system1 the water company demands that a check valve be placed on the hot-water system to prevent the hot water from being forced back into the meter in case the pressure got strong enough in the boiler4 ,if a check valve is used for this purpose1 or for any other purpose1 a safety valve must be placed on the boiler piping system to relieve any excessive pressure that may be caused by having the check valve in use4 ,there is today1 with meters of modern type1 no reason to use a check valve or a safety valve4 ,if an excessive pressure is obtained in the boiler1 it is relieved in the water main4 ,when water is heated1 it expands4 ,if the heat becomes more intense and steam is formed1 the expansion is much greater1 and some means must be provided to allow for it4 ,this expansion can be allowed to relieve itself in the water main as explained above4 ,when a check valve is placed on the piping1 this means of escape is shut off and a safety valve must be employed4 ,without these reliefs1 the pressure would be so great that an explosion would result4 ,when steel pipe and steel boilers are used for storage tanks and connections1 the pipe and tank will shortly start to rust and parts of the piping are stopped up with rust scales4 ,the water also becomes red with rust when the water becomes hot enough to circulate4 ,when the pipes are stopped up1 steam is formed and a snapping and cracking sound is heard4 ,to avoid these conditions1 the piping should be of brass or lead and the storage tank should be of copper4 ,the installation cost of brass and copper is greater than steel1 but they will not have to be replaced in two or three years1 as is the case with other material4 ,a valve should be placed on the cold-water supply to control the entire hot-water piping system4 ,a pipe with a stop cock should be placed underneath the boiler and should extend into a sink in the basement so that the boiler can be drained at any time for cleaning or repairs4 ,,connecting ,,with ,,fixtures4--,to have all fixtures properly supplied with hot water it is necessary to run what is termed a circulating pipe4 ,this circulating pipe is a circuit of pipe extending from the top of the boiler to the vicinity of the fixtures and then returning to the boiler and connecting into the pipe leading out of the bottom of the boiler4 ,from this circuit all branches are taken to supply all fixtures requiring hot water4 ,this circulating pipe has hot water circulating through it all the time4 ,therefore the fixtures are supplied with hot water very quickly4 ,the circulating pipe and its branches are run without any traps or air pockets4 ,illustration3 ,,fig4 #gc4--;,expansion loop4 ,four #ij deg4 ells4 ,illustration3 ,,fig4 #gd4--;,expansion loop4 ,five #ij deg4 ells4 ,illustration3 ,,fig4 #ge4--;,expansion loop4 ,six #ij deg4 ells4 ,when running the piping1 it should be borne in mind that not only does the water expand when heated1 but the pipe expands also4 ,therefore due allowance must be made for this expansion4 ,the long risers should have an expansion loop as shown in ,figs4 #gc1 #gd and #ge4 ,there are installed on some jobs what is known as an expansion joint4 ,this will allow for the expansion and contraction of the pipe4 ,the writer's experience with these joints has not been very satisfactory4 ,after a while these joints begin to leak and they must have attention which in some cases is rather expensive4 ,an expansion loop as shown in the sketch1 made with elbows1 will prove satisfactory4 ,if the threads on the fittings and pipe are good1 no leak will appear on this joint4 ,all gas heaters must be connected with a flue to carry off the products of combustion4 ,,chapter ,,xv ,,insulation ,,of ,,piping ,,to ,,eliminate ,,conduction1 ,,radiation1 ,,freezing1 ,,and ,,noise ,,pipe ,,covering4--,pipe covering is another important branch of plumbing4 ,a few years ago heating pipes were the only pipes that it was thought necessary to cover4 ,the ever-increasing demands made by the public keep the wideawake plumber continually solving problems4 ,the water running down a waste pipe1 for instance1 will annoy some people1 and provision must be made to avoid this noise or to silence it4 ,this is one of the many problems that the plumber must solve by the use of pipe covering4 ,,pipes ,,that ,,need ,,covering4--,first of all1 the covering must be put on properly to be of high service4 ,hot-water circulating pipes need covering to reduce the amount of heat loss4 ,if the pipes and the tank are not covered1 considerable more fuel will be needed to supply the necessary amount of hot water than if the pipes and tank were covered with a good covering4 ,cold-water pipes need covering in places to keep them from freezing4 ,they also need covering under some conditions to keep them from sweating4 ,they are covered also to prevent the material which surrounds them from coming into direct contact with the pipe4 ,waste pipes need covering to prevent them from freezing and to silence the noise caused by the rush of water through them4 ,ice-water pipes are covered to prevent the water from rising in temperature and to prevent any condensation forming on the pipe4 ,there is need for such a variety of covering that ,i have listed below some of them and the methods employed for putting them on the pipe4 ,magnesia1 asbestos air cell1 molded asbestos1 wool felt1 waterproof paper and wool felt1 cork1 hair felt4 ,these coverings come in the form of pipe covering with a cloth jacket4 ,they also come in the shape of fittings as well as in blocks and rolls of paper1 and in powdered form4 ,any thickness that is desired may be had4 ,the pipe covering is readily put on the pipe4 ,the cloth jacket is pulled back a short distance and the covering will open like a book4 ,it can then be clamped on the pipe and the jacket pulled back and pasted into place4 ,brass bands1 #a inch wide1 come with the pipe covering4 ,these are put on and the pipe covering is then held securely in place4 ,practically all the coverings are applied in this manner and are made up in #c-;foot lengths to fit any size pipe4 ,to cover the fittings and valves1 the same kind of sectional covering can be obtained and applied in the same manner as the pipe covering4 ,plastic covering is often applied to the fittings and molded into the shape of the fitting4 ,the plastic covering comes in bags and is dry4 ,it is mixed with warm water to the consistency of thick cement and applied with a trowel4 ,when the covering is put on the pipes and fittings1 it should be done thoroughly to get satisfactory results4 ,each section of the covering has on one end an extra length of the jacket4 ,this is to allow a lap over on the next section to make a tight joint4 ,if the sections need fitting1 a saw can be used and the covering cut to any desired length4 ,magnesia covering is employed mostly on steam pipes1 especially high-pressure4 ,this material can be had in the shape of pipe covering1 in blocks1 or cement4 ,asbestos air cell covering is employed to cover hot-water circulating pipes4 ,it is constructed of corrugated asbestos paper4 ,this material is manufactured in the sectional pipe covering or in corrugated paper form4 ,molded asbestos covering is also used on hot-water pipes1 and is manufactured in pipe covering or in blocks4 ,wool felt covering is used mostly on hot-water pipes and makes one of the best coverings4 ,it is lined with asbestos paper and covered with a cloth jacket4 ,waterproof paper and wool felt is used on cold-water pipes and is made in #c-;foot lengths4 ,the covering is lined with waterproof paper and covered with a cloth jacket4 ,cork4--,a heavy cork covering is one of the best coverings for ice-water pipes1 and a light cork covering is used for cold-water pipes4 ,this covering comes in sections as other coverings1 also in blocks and sheets4 ,hair felt is used to prevent pipes from freezing4 ,it comes in bales containing #aej to #cjj square feet of various thicknesses4 ,,chapter ,,xvi ,,durham ,,or ,,screw ,,pipe ,,work4 ,,pipe ,,and ,,fittings ,durham or screw pipe work is the name used to denote that the job is installed by the use of wrought-iron or steel screw pipe4 ,we speak of a cast-iron job meaning that cast-iron pipe was used for the piping4 ,a completely different method of work is used when screw pipe is employed for the wastes and vents4 ,when screw pipe is to be used or considered for use1 it is well to know something concerning the various makes of screw pipe4 ,nothing but galvanized pipe is ever used4 ,the value of steel screw pipe and wrought-iron screw pipe should be studied1 and every person interested should1 if possible1 understand how these different pipes are made and how the material of which they are composed is made4 ,in some places one pipe is better than another and a study of their make-up would enlighten the user and allow him to use the best for his peculiar conditions4 ,the maker's name should always be on the pipe4 ,the following table shows the sizes1 weights1 and thicknesses of screw pipe3 ------------------------------- ,size ,thickness ,no4 threads per inch ------------------------------- #a-a_/d #j4adj #aa-a_/b #a-a_/b #j4ade #aa-a_/b #b #j4aed #aa-a_/b #b-a_/b #j4bjd #h #c #j4bag #h #c-a_/b #j4bbf #h #d #j4bcg #h #e #j4bei #h #f #j4bhj #h ------------------------------- ,screw pipe work came into common use with the advance of modern steel structures4 ,some difficulty had been experienced in getting the cast-iron pipe joints tight and to keep the pipe so anchored that it would not crack4 ,the screw pipe was found to answer all of the requirements of modern structures and therefore has been used extensively4 ,the life of screw pipe is not as long as extra heavy cast-iron pipe4 ,this is the only serious objection to screw pipe1 which must be renewed after a term of years1 while extra heavy cast iron lasts indefinitely4 ,screw pipe is never used underground4 ,when piping is required underground1 extra heavy cast-iron pipe is used4 ,,piping ,the pipe used in ,durham work is galvanized extra heavy1 or standard wrought-iron1 or steel pipe4 ,it is almost impossible to recognize wrought-iron from steel pipe without the aid of a chemical or a magnifying glass4 ,to test the pipe to distinguish its base1 take a sharp file and file through the surface of the pipe that is to be tested4 ,if the pipe is steel1 under a magnifying glass the texture of the filed surface will appear to be smooth and have small irregular-shaped grains1 and there will also be an appearance of compactness4 ,if the pipe is iron1 the texture will have the appearance of being ragged and will show streaks of slag or black4 ,when screw pipe is cut there is always left a large burr on the inside of the pipe4 ,this burr greatly reduces the bore of the pipe and is a source of stoppage in waste pipes4 ,after the pipe is cut this burr should be reamed out thoroughly4 ,one of the strong points of screw pipe is the strength of each joint4 ,care should therefore be taken to see that perfect threads are cut on the pipe and that the threads of the fittings are perfect4 ,the dies should be set right and not varied on each joint4 ,there should be plenty of oil used when threads are cut so that the thread will be clean and sharp4 ,the follower or guide on stocks should be the same size as the pipe that is being threaded1 otherwise a crooked thread will result4 ,if a pipe-threading machine is used1 the pipe is set squarely between the jaws of the vise that holds the pipe in place4 ,when cutting a thread on a long length of pipe1 the end sticking out from the machine must be supported firmly so that no strain will come on the machine as the pipe turns4 ,it is necessary to cut crooked threads sometimes on the pipe to allow the pipe pitch for drainage or to bring the pipe into alignment where fitting would take up too much room4 ,to cut a crooked thread on a piece of pipe1 simply leave the follower out of the stock or put in the size larger4 ,the dies not having a guide will cut a crooked thread4 ,piping should be run with as few threads as possible4 ,with a thorough knowledge of and the intelligent use of fittings1 a minimum number of threads will result4 ,the pipes in a building are run in compact parallel lines in chases designed especially for them4 ,the tendency is to confine the pipes to certain localities as much as possible4 ,this makes a very neat job and in case repairs are needed1 the work and trouble incurred will be confined to one section4 ,,fittings ,the fittings used in screw pipe work are cast-iron recess type 7see ,fig4 #ed74 ,the fittings are so made that the inside bores of the pipe and the fittings come in direct line with each other1 thus making a smooth inside surface at all bends4 ,the fittings are all heavily galvanized4 ,all fittings should be examined on the inside for any lumps of metal of sufficient size to catch solid waste matter1 and these must be removed or the fitting discarded4 ,all #ij deg4 bends1 whether ,ts or elbows1 are tapped to give the pipe that connects with them a pitch of at least #a_/d inch to the foot4 ,except where obligatory1 #ij deg4 fittings should not be used4 ,to make a bend of #ij deg4 a ,y-branch1 a nipple and a #de deg4 bend should be used1 or two #de deg4 bends will make a long easy sweep of the drainage pipes and reduce the possibility of stoppage4 ,y-branches are inserted every #cj feet at least to allow for a clean-out which can be placed in the branch of the fitting4 ,when a clean-out is placed an iron plug should not be used4 ,these plugs are not removed very often and an iron plug will rust in and be almost impossible to get out4 ,brass clean-out plugs are used and are easily taken out4 ,at times it is necessary to connect cast iron and wrought iron1 or in a line where a union could be used if the pipe were not a waste pipe1 a tucker fitting is used4 ,this fitting is threaded on one end and has a socket on the other to allow for caulking4 ,to get a good idea of all the fittings in general use1 the reader should get a catalogue from one of the fitting manufacturers and a survey of it will give the names and sizes of the fittings4 ,however1 ,i show a few common ones4 ,in the writer's opinion1 the studying of the catalogue would be of more benefit than a description of fittings at this point4 ,the sizes used and the methods employed to vent the waste-pipe systems are the same as in cast-iron work4 ,,hangers ,,and ,,supports ,the hanging of screw pipe is a very essential point4 ,the taking of the strain off from a fitting or line of pipe by the use of a hanger is the means of avoiding serious trouble after a job is completed4 ,on horizontal runs hangers are placed not more than #h feet apart4 ,in a building constructed of wood1 the hangers are secured to the joists4 ,in a building constructed of steel beams and concrete the hangers are secured to the steel beams by means of ,i-beam hangers that clamp on the beams2 also in the case of concrete the hangers are extended through the floor and a ,t is put on the hanger on top of the cement floor2 an iron bar or a short piece of smaller pipe run through the ,t holds the hanger in place and secures it rigidly4 ,the finished floor is laid over the hanger so that it does not show from the top4 ,hangers on the vertical lines should be placed at every joint and under each fitting4 ,to have the pipe in true alignment1 the hangers must be hung and placed in line4 ,every riser line must have an extra support at the base to avoid any settling of the stack which will crack the fittings and break fixture connections4 ,,measurements ,the proper installation of screw pipe work requires getting correct and accurate measurements4 ,every plumber is or should be able to get correct center to center1 center to end1 end to end1 center to back1 and end to back measurements4 ,in ,durham work #de deg4 angles are continually occurring4 ,to get these measurements correctly1 the following table has been compiled as used by the author and found to be correct4 ,the reader should memorize it so that it may be used without referring to the book4 ,,measurements ------------------------------------- ,soil pipe ,screw pipe ,multiplier ------------------------------------- #a_/f bend #fj #a4ae #a_/h #de #a4da #a_/ab #cj #b4 #a_/af #bb-a_/b #b4fa #a_/cb #aa-a_/d #e4ab #a_/fd #e-e_/h #aj4bb ------------------------------------- ,before any measurements are taken1 the lines of pipe are laid out and the position of each fitting known4 ,as ,i have stated before1 the plumber must look ahead with his work4 ,he must have the ability of practically seeing the pipe in place before the work is started4 ,this requires experience and judgment4 ,before the measurements are taken and the pipe cut consideration must be given to the fact that the fittings and pipes must be screwed into position4 ,therefore1 can the fitting on the pipe be placed where it is laid out when this is considered8 must be one of the many questions a plumber should ask himself4 ,allowance must be made for the chain tongs to swing4 ,whenever possible1 a fitting is made up on the pipe while the pipe is in the vise4 ,illustration3 ,,fig4 #gf4--,the offset is ,b or #ab inches center to center4 ,the offset is made using #de degree fittings4 ,therefore the length of ,a from the center of one fitting to the center of the other is ,b x #a4da #ab x #a4da #af4ib inches4 ,,fixture ,,connections ,the fixture connections when screw pipe is used are necessarily different than when cast-iron pipe is used4 ,a brass nipple is wiped on a piece of lead pipe and then screwed into the fitting left for the closet connection4 ,the lead is flanged over above the floor and the closet set on it4 ,the lead is soldered to a brass flange4 ,the brass flange is secured to the floor and then the closet bowl secured to the brass flange4 ,another method employed is to screw a brass flange into the fitting so that when it is made up the flange will come level with the floor2 the closet bowl is then secured to this flange4 ,there are a number of patented floor flanges for closet bowl connections that can be used to advantage4 ,slop sinks have practically the same connections as the closets4 ,other fixtures such as the urinal1 lavatory1 and bath1 can be connected with a short piece of lead wiped on a solder nipple1 or the trimmings for the fixture can be had with brass having iron pipe size threads1 and the connection can then be made directly with the outlet on the waste line4 ,this is a very general way to describe the connections1 but space will not allow a detailed description of these connections4 ,it is always well to allow for short lead connections for fixtures so that the lead will give if the stack settles4 ,,chapter ,,xvii ,,gas ,,fitting1 ,,pipe ,,and ,,fittings1 ,,threading1 ,,measuring1 ,,and ,,testing ,,gas ,,and ,,its ,,use ,,in ,,buildings ,gas is in common use in all classes of buildings today4 ,dwellings use it for cooking and illuminating1 factories1 office buildings1 and public buildings for power4 ,in some parts of the country natural gas is found4 ,in these places it is used freely for heating fuel4 ,the actual making of gas is something that every plumber should understand4 ,if space permitted ,i would describe a gas plant with all of its by-products4 ,however1 we shall deal only with the actual installation of gas piping in buildings4 ,gas mains are run through the streets the same as water mains are run4 ,branches are taken off these mains and extended into the buildings requiring gas4 ,the gas company generally installs the gas service pipe inside of the basement wall and places a stop cock on it free of charge4 ,this stop that is placed on the pipe is a plug core type1 the handle for turning it off is square1 and a wrench is required to turn it4 ,the square top has a lug on it4 ,there is also a lug corresponding to it on the body of the valve4 ,when the valve is shut off1 these two lugs are together4 ,each lug has a hole in it large enough for a padlock ring to pass through4 ,this gives the gas company absolute control of the gas in the building4 ,,setting ,,of ,,the ,,meter4--,every building that is supplied with gas has a meter that registers the amount of gas consumed4 ,this meter is placed on the service pipe on the house side of the above-mentioned stop cock4 ,this meter is furnished free of charge with a trivial charge made for setting up4 ,the actual setting of this meter is not made until the piping throughout the building has had a thorough and satisfactory test and is found free from all leaks4 ,the meter must be set level on a substantial bracket and in a place1 if possible1 where it will not require an artificial light to read its dial4 ,the dry meter is usually used in dwellings4 ,the interesting construction and mechanism of this meter cannot be discussed here4 ,illustration3 ,,fig4 #gg4--;,gas-meter dials4 ,the reading of the dials on a gas meter comes in the province of the plumber and he should be able to read them4 ,the sketch shows the dial plate of a meter4 ,the ordinary house meter has only three recording dials4 ,large meters have five or more4 ,to read the amount of gas consumed according to the meter we will read the dials as they are indicated on ,fig4 #gg4 ,we will call the four dials ,no4 #a1 ,no4 #b1 ,no4 #c and ,no4 #d4 ,in each of these dials a complete revolution of the index hand denotes #a1jjj1 #aj1jjj1 #ajj1jjj and #a1jjj1jjj1 cubic feet respectively4 ,the index hands on ,no4 #a and ,no4 #c revolve in the same direction1 while ,no4 #b and ,no4 #d revolve in the opposite direction4 ,two ciphers are added to the figures that are indicated on the dials and the statement of the meter will be had4 ,to tell just how much gas has been consumed in a given time1 the statement of the meter is taken at the beginning of this given time and at the end of the time4 ,the difference in the figures indicates the number of cubic feet of gas that have been consumed4 ,a gas cock should be placed on the house side of the meter4 ,the dials of meter read #feh1hjj cubic feet4 ,the dial having the highest number is read first ,no4 #d dial points to #f1 this indicates that ,no4 #c dial has revolved #f times4 ,dial ,no4 #c reads #e1 therefore the reading of dial ,no4 #c and ,no4 #d is #fe4 ,dial ,no4 #b reads #h making the readings of the three dials #feh4 ,dial ,no4 #a reads #h making the readings of the four dials #fehh add two ciphers to this figure and #feh1hjj is the correct reading4 ,illustration3 ,,fig4 #gh4 ,illustration3 ,,fig4 #gi4 ,,pipe ,,and ,,fittings4--,the pipe used in gas fitting is wrought iron or steel4 ,in special places1 rubber hose is used4 ,brass pipe is occasionally used to advantage4 ,the fittings used in iron pipe gas work should be galvanized4 ,no plain fittings should be allowed4 ,the plain fittings very often have sand holes in them and a leak will result4 ,sometimes this leak does not appear until after the piping has been in use some time and the expense of replacing the fitting can only be guessed at4 ,by using galvanized fittings1 this trouble will be eliminated4 ,all fittings used should be of the beaded type4 ,the fitting and measurement of this work is practically the same as described under iron pipe work4 ,to have the beginner get a clearer idea of gas-piping a building1 the piping of the small building sketched will be gone over in detail and studied4 ,one of the first important steps that a gas fitter is confronted with is the locating of the various lights and openings4 ,with these located as shown on the plan1 ,figs4 #gh1 #gi and #hj1 we will proceed to work out the piping4 ,the first floor rise will be #a-;inch1 the second floor will be #a-;inch4 ,the horizontal pipe supplying the first floor outlets will be #c_/d-;inch pipe4 ,the horizontal pipe on the second floor will be #c_/d-;inch4 ,the balance of the pipe will be #c_/h- or #a_/b-;inch4 ,at this point your attention is called to the sketch of piping1 sizes1 and measurements4 ,this sketch should be studied and understood in detail4 ,the good mechanic will employ a sketch of this kind when installing any piping4 ,the poor mechanic will take two or three measurements and get them out1 put them in1 and then get some more4 ,this method is extremely costly and unworkmanlike4 ,there is no reason1 except the ability of the workman1 why he cannot take a building like the sketch and get all the piping measurements for the job1 then get them out1 go to the job and put them in4 ,the amount of time saved in this way is so great that a workman should not consider himself a full-fledged mechanic until he can get the measurements this way1 and get them accurately4 ,with a tape line1 gimlet1 and plumb-bob1 a mechanic is fully equipped with tools to get his measurements4 ,if the measurements are taken with a tape line1 the same tape line should be used when measuring the pipe and cutting it4 ,when laying out the piping1 never allow a joist to be cut except within #f inches of its bearing4 ,it is good policy never to cut timber unless absolutely necessary and then only after consulting with the carpenter4 ,when joists have to be notched they should be cut only on the top side4 ,the pipe as it is put in place should be braced rigidly4 ,wherever there is an outlet pipe extending through the wall1 the pipe should be braced from all sides so that when the fixture is screwed in it will be perfectly rigid4 ,illustration3 ,,fig4 #hj4 ,illustration3 ,,fig4 #ha4--,pipe sketch4 ,the measurements on the piping sketch1 ,fig4 #ha1 are taken from the accompanying sketch of a dwelling1 and if they were to be actually put in1 they would fit4 ,the reader would do well to copy this sketch and follow the piping and check the measurements according to the plan1 and note how the different risers1 drops1 etc41 are drawn4 ,it is not necessary in a sketch of this kind to draw to a scale4 ,after the different measurements are the letters ,c4,c41 ,e4,c41 ,e4,e41 ,c4,b4 and ,e4,b41 meaning center to center1 end to center1 end to end1 center to back1 and end to back1 respectively4 ,offsetting pipe is a very convenient way of getting the pipe or fittings back to the wall for support4 ,to offset pipe properly and with little trouble1 take a piece of scantling #b by #d and brace it between the floor and ceiling4 ,bore a few different-sized holes through it and you will have a very handy device for offsetting pipe4 ,there is a little trick in offsetting pipe that one will have to practice to obtain4 ,the pipe must be held firmly in the place where the pipe is to be bent4 ,large offsets and bends should not be made2 #b to #d inches is as large as should be used4 ,larger offsets that are required should be made with fittings4 ,always make the offsets true and have the ends perfectly straight4 ,before putting a piece of pipe permanently in place1 always look or blow through it1 to ascertain if its bore is obstructed or not4 ,sometimes dirt or slag will collect and cause stoppage4 ,,reading ,,the ,,pipe ,,sketch4--,vertical lines represent vertical pipes 7see ,fig4 #ha74 ,horizontal lines represent horizontal pipes running parallel to the front4 ,diagonal lines represent horizontal pipes running from back to front4 ,any line that is drawn perpendicular to any other line stands for a horizontal pipe4 ,a diagonal line separating a vertical line or horizontal line or set of lines represents a different horizontal plane4 ,with this explanation the sketch will be made clear to one after drawing it4 ,the reader should now take each measurement and check it on the plan4 ,this is easily done by using a scale rule4 ,the height of the ceiling is #h-a_/b feet on the first floor1 the second floor is #h feet4 ,the first floor joists are #aj inches1 the second floor joists are #i inches4 ,an outlet is indicated by a small circle4 ,in the piping sketch1 this circle is connected with the riser or drop by a horizontal line4 ,at the junction of these two lines a short perpendicular line is drawn1 and indicates the direction of the outlet4 ,let me again emphasize the need to understand thoroughly this piping sketch1 and to become so familiar with it that it can readily be put to use4 ,the value of a mechanic is determined by the quality and the quantity of work that he can turn out2 and a mechanic who can lay out his work and see it completed before he starts1 and then proceeds to install his work1 is by far of more value to his employer than the man who can see only far enough ahead to cut out two or three measurements and spends most of his time walking between the vise and place of installing the pipe4 ,,testing4--,the system of gas piping must be tested before the pipes have been covered by the advance of building operations4 ,if the job is of considerable size1 the job can be tested in sections1 and if found tight the sections can be covered4 ,the necessity of having the piping rigidily secured can be appropriately explained here4 ,if the test has been made and the system found tight and some pipe that is not securely anchored is accidentally or otherwise pushed out of place and bent by some of the mechanics working about the building1 a leak may be caused and yet not discovered until the final test is made after the plastering is finished4 ,the expense and trouble thus caused is considerable and could have been avoided by simply putting in the proper supports for the pipe4 ,to test the piping1 an air pump and a gage connected with the pipes are placed in a convenient position4 ,the job should now be thoroughly gone over1 making sure that all plugs and caps are on and that no outlet is open1 also that all pipe that is to be put in has been installed4 ,after this has been attended to1 the pump is operated until #aj pounds is registered on the gage4 ,the connection leading to the pump and the piping is now shut off4 ,if the gage drops rapidly1 there is a bad leak in the system4 ,this leak should be found without difficulty and repaired4 ,if the gage drops slowly1 it denotes a very small leak1 such as a sand hole or a bad thread4 ,this kind of leak is more troublesome to find4 ,when it has been found1 the pipe or fitting causing the leak should be taken out and replaced4 ,if black caps have been used to cap the outlets1 the chances are that a sand hole will be found in one of them4 ,nothing but galvanized fittings should be used4 ,in case the small leak mentioned above cannot be found by going over the pipe once1 there are other means of locating the leak4 ,two of the methods used1 ,i will explain4 ,if the job is small1 each fitting is painted with soap suds until the fitting is found that causes the leak4 ,if the leak is not in the fittings1 then the pipe can be gone over in the same way4 ,as soon as the soap suds strikes the leak1 a large bubble is made and the leak discovered4 ,it is possible that there are more leaks1 so the gage is noted and if it still drops1 the search should be continued4 ,the pump should be operated to keep the pressure up to #aj pounds while the search is being made for the leak4 ,when the gage stands at #aj pounds without dropping1 the job is then tight4 ,the pump and gage fitting should be gone over first to ascertain if they leak4 ,the other method employed to discover leaks is to force a little ether or oil of peppermint 7not essence7 into the system by means of the pump4 ,a leak can readily be noted by the odor4 ,to make this method successful1 the ether or peppermint should not be handled by the men who are to hunt for the leak4 ,the bottle containing the fluid should not be opened in the building except to pour some into the piping1 otherwise the odor will get into the building and as the odor comes out of the leak it will not be noted4 ,for the benefit of the gas fitter1 the piping should be tested again after the plastering is completed4 ,the next test is made when the fixtures are put on1 and as the piping is tight any leak that develops in this test indicates that the fixtures leak4 ,there are in common use various methods to stop leaks in gas pipe when they are found4 ,if a piece of piping or a fitting is defective1 it should be taken out and replaced4 ,this should be remembered so that while the piping is being installed any defects should be noted and the defective fitting or pipe thrown out4 ,before the gas job is accepted1 the gas company will inspect it and look for traps and sags in the pipe4 ,therefore1 the piping should be installed without any traps and it should be arranged to pitch toward the meter1 or toward a convenient place from which any condensation can be taken out4 ,if provision is not made for this condensation1 it will accumulate and stop the flow of gas4 ,,shower-,,bath ,,connections ,illustration3 ,,fig4 #hb4--,shower stall with lead pan extending outside of stall4 ,the sketches show clearly the methods employed to make a shower-bath waste and stall water-tight4 ,the shower bath1 as a separate fixture1 is in use and the demand for it as a separate fixture is increasing rapidly4 ,this demand comes from the owners of private houses4 ,the plumber must therefore devise some way to make these connections tight and prevent any leak from showing in the room below4 ,this fixture is so constructed that all waste pipes and trap come under the floor level with no way of getting to them from below4 ,therefore the piping for this fixture must be of a permanent nature4 ,no pipe or trap made of material that is liable to give out in a short time should be allowed under a shower-bath fixture or stall4 ,the two sketches1 ,figs4 #hb and #hc illustrate two methods of connecting and making tight a shower stall4 ,a plumber should always consider it his special duty to make his work complete and free from all objections4 ,he should always prepare for any emergency that may occur in the future4 ,this is rather a big task1 yet the plumber when accepting all of his responsibilities has a big task4 ,i state this to the beginner and emphasize the all-important fact that he must learn to perform and think deeply of the elements of plumbing to be able later on to handle successfully the problems that present themselves in the plumbing trade4 ,illustration3 ,,fig4 #hc4--,shower stall with lead pan extending six inches beyond strainer4 ,the heavy brass trap shown in the sketch has proved itself very satisfactory and can be made to fit almost any condition of piping or building construction4 ,a flashing of sheet lead is soldered on the trap and carried out to the outside edge of the stall where it is turned up #a inch1 or to the floor level4 ,when the flashing is carried out for only a foot on each side of the trap1 the possibilities of a leak are greater4 ,,chapter ,,xviii ,,plumbing ,,codes ,the work of plumbing has a direct result on the health of the occupants of buildings2 therefore in order that the plumbing may not be installed improperly and impair the health of the occupants1 it is necessary to provide a code governing the installation of plumbing4 ,naturally these laws at first were under the control of the health department of cities1 but of late years the building departments have assumed control of the codes with the result that cooperation with the building codes is now the practice rather than the exception4 ,to make certain the carrying out of the plumbing codes1 it is required that a plan indicating the run1 size1 and length of pipes1 location and number of fixtures of the prospective job be filed in the building department of the city1 before the work is started4 ,if the plan is approved by the plumbing inspector and acceptance is sent1 then the work can be started4 ,after a job is completed a test is made and the job is inspected by the plumbing inspector1 and if found to meet requirements a written acceptance of the work is given by the building department4 ,an effort is being made throughout the country to have the plumbing codes under ,state control rather than have a number of different codes in as many different cities and towns4 ,the ,state code can be so arranged that it will apply to either city or town4 ,the installation of plumbing varies in different ,states4 ,in the northern part of the ,united ,states all pipes which pass through the roof1 if less than #d-;inch must be increased to #d-;inch4 ,a pipe smaller than #d-;inch will be filled with hoar frost during the winter and render the pipe useless to perform its function as a vent pipe4 ,pipes laid under ground in the ,northern ,states must be at least #d feet below the surface to protect them from freezing4 ,in the ,southern ,states the frost does not penetrate the ground to such a distance and the pipes can be laid on the surface4 ,following is a ,state or ,city plumbing code insofar as it relates to the actual installation of plumbing4 ,,sec4 #a4 ,,plans ,,and ,,specifications4--,there shall be a separate plan for each building1 public or private1 or any addition thereto1 or alterations thereof1 accompanied by specifications showing the location1 size and kind of pipe1 traps1 closets and fixtures to be used1 which plans and specifications shall be filed with the board or bureau of buildings4 ,the said plans and specifications shall be furnished by the architect1 plumber or
