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 Plumbing. As a consequence each exercise is minutely described and illustrated; so much so, perhaps, that an experienced mechanic may find it too simple for skilled hands and a mature mind. But the beginner will not find the exercises too elaborately described and will profit by careful study. Years of experience and observation have shown the author that the methods herein described are entirely practical and are in common use today.
The various exercises in lead work will acquaint the beginner with the correct use of tools and metals. The exercises in iron pipe work have also been detailed to show the correct installation of jobs.
Together with the study of this book the subjects of Mathematics, Physics, Chemistry, Drawing and English should be taken. These subjects as they bear on Plumbing are invaluable to the mechanic in his future connection with the trade.
The author is indebted for the illustrations of fixtures in the chapter covering the development of plumbing fixtures, to the Thomas Maddock’s Sons Co., Standard Sanitary Mfg. Co., and The Trenton Potteries Co.

ELEMENTS OF PLUMBING

CHAPTER I

Plumbing Fixtures and Trade

Modern plumbing as a trade is the arranging and running of pipes to supply pure water to buildings, the erecting of fixtures for the use of this supply, and the installing of other pipes for the resulting waste water. The work of the trade divides itself therefore into two parts: first the providing an adequate supply of water; and second, the disposing of this water after use. The first division offers few problems to the plumber, little variety in the layout being possible, and the result depending mostly upon the arrangement of the pipes and fittings; but the second division calls for careful study in the arrangement, good workmanship in the installing, and individual attention to each fixture.
The trade had its beginnings in merely supplying fresh water to a community. This was done by means of trenching, or conveying water from lakes, rivers, or springs through wooden pipes or open troughs. By easy stages the trade improved and enlarged its scope, 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 works.
In the early years of the trade the question of the disposal of the waste water was easily answered, for it was allowed to be discharged onto the ground to seek its own course. But with the increased amount of water available, the waste-water problem has enlarged until today it plays the most important part of plumbing, and the trade has had to change to meet this waste-water problem.
The first simple system of a pipe running from the sink to a point outside the building was sufficient. As larger buildings came into use and communities were more thickly populated, the plumbing problem demanded thought and intense study. 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 fixture. The importance of this is evidenced by the plumbing laws now in use throughout the country.
One of the first plumbing fixtures put into common use was a hollowed-out stone which served as a sink. It was with considerable interest that the writer saw a sink of this kind in actual use in the summer of 1915, at a house in a New England village. This sink had been in service for about 100 years. From this beginning the well-known fixtures of today have developed. The demand for moderate priced, sanitary closets, lavatories, and baths has led to the rapid improvement seen in plumbing fixtures. In the development of these fixtures, as soon as a bad feature was recognized the fixture was at once discarded, until now the market offers fixtures as mechanically fine as can be produced. Plumbing fixtures were at first manufactured so that it was necessary to support them on a wooden frame, and this frame was enclosed in wood. The enclosure made by this framework soon became foul and filthy and a breeding place for all kinds of disease germs and vermin. This bad feature was overcome by the introduction of open plumbing, that is, fixtures so made that the enclosure of wood could be done away with. The open plumbing allowed a free circulation of air around the fixture and exposed pipes, thereby making the outside of the fixture and its immediate surroundings free from all the bad features of the closed plumbing. Plenty of fresh air and plenty of light are necessary for good sanitary plumbing.
Fig. 1.—Pan closet (English).
The materials of which the first open-plumbing fixtures were made consisted of marble, copper, zinc, slate, iron, and clay. Time soon proved that marble and slate were absorbent, copper and zinc soon leaked from wear, iron rusted, and clay cracked and lacked strength; therefore these materials soon became insanitary, and foul odors were easily detected rising from the fixture. Besides these materials being insanitary, the fact that a fixture was constructed using a number of sections proved that joints and seams were insanitary features on a fixture. For instance, in a marble lavatory constructed by using one piece for the top, another for the bowl, and still another for the back, filth accumulated at every joint and seam. Following this condition, developed the iron enameled and earthenware fixtures, constructed without seams and with a smooth, even, glossy white finish. The fact that these fixtures are made of material that is non-absorbent adds to their value as sanitary plumbing fixtures.
Another problem which is as important as the foregoing is the proper flushing, that is, the supplying of sufficient water in a manner designed to cleanse the fixture properly.
The development of sanitary earthenware illustrates how the above problems were satisfactorily solved. In the city of London a law compelling the use of drains was enforced, and in the early 70’s the effect of this law was felt in this country. The introduction at this time of the mechanical water closet, known as the “pan closet,” and the English plumbing material which was brought to this country was the beginning of “American plumbing,” which today outstrips that of any other country in the world. The “pan closet” continued in use for some time until the “valve closet” was introduced as a more sanitary fixture. Closely following these closets, in 1880, the plunger closet became popular as a still more sanitary fixture. The plunger closet continued in use until the present all-earthenware closet bowl drove all other makes from the market. The American development of the earthenware closet bowl put the American sanitary fixture far ahead of the English improvements, as the American earthenware is superior and the sanitary features of the bowls are nearer perfection.

Fig. 3.—Plunger closet.

When the washout bowl was introduced it was considered perfection. The hopper closet bowl, which was nothing more than a funnel-shaped bowl placed on top of a trap, was placed in competition with the washout bowl. There are a number of these bowls now in use and also being manufactured. However, large cities prohibit their use.

Fig. 4.—Plunger closet.

To quote Thomas Maddock’s Sons Co.: “In 1876 Wm. 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 potter, who had gradually and by costly experiment become the determining factor in the evolution of the water closet.” With this improvement it became possible to do away with the boxing-in of the bowl which up to this time had been necessary. Closet bowls of today are made of vitreous body which does not permit crazing or discoloring of the ware. 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 journeyman. The bath tub developed from a gouged-out stone, in which water could be stored and used for bathing purposes, to our present-day enameled iron and earthenware tubs. The development did not progress very rapidly until about 25 years ago. Since then every feature of the tub has been improved, and from a sanitary standpoint the tubs of today cannot be improved. The bath tub has become an American custom, as the people in this country have demanded that they have sanitary equipment in their homes, while in the European countries this demand has not developed.

Fig. 5.—Modern low-tank closet.

The first tubs used in this country were of wood lined with copper or zinc, and were built in or boxed in with wood panelling. The plumbing ordinances of today prohibit this boxing as it proved to be a breeding place for vermin, etc. As the illustration shows, the woodwork encasing the tub was in a great many cases beautifully carved and finished.
The placing on the market of a steel-clad tub, a steel tub with a copper lining, which did away with the boxing, was a big improvement as far as sanitary reasons were concerned as well as a reduction in cost of tubs. These tubs were set up on legs which permitted cleaning and provided good ventilation all around. With these features they drove all other tubs from the market. The copper and zinc were found to be hard to keep clean and they were soon replaced by the iron enamelled and earthenware tubs. The finish on these tubs being white and non-absorbent makes them highly acceptable as sanitary fixtures. A study of the illustrations will show how progress has been made in design as well as in sanitary features.

Fig. 7.—Steel tub on legs.

The Wash Bowl.—Succeeding the hand basin the first wash basins used in this country were made of marble or slate, with a round bowl of crockery. The bowl was 14 inches in diameter originally, but later was changed to an oval bowl. Like the bath tub these wash stands were encased in wood, the encasing being used to support the marble top. Ornamental brackets were introduced and the wood encasement done away with.

Fig. 9.—Encased wash bowl.

About 1902 the iron-enamelled lavatory appeared on the market and drove all other kinds from the market at once. The reason for this is clear. The marble stands were absorbent and were made with three parts, top, back, and bowl; the enamelled iron lavatory is made all in one piece of material non-absorbent. A study of the illustrations will show clearly how the lavatory has been improved. Strange to say, in all plumbing fixtures, and especially the lavatory, as improvements were made to make them more sanitary a reduction has been made in the price of an individual fixture.

The development of the urinal, showers, wash trays, drinking fountains and other fixtures I will not attempt to cover. As the demand has been evident for fixtures of certain types, the plumber has been alert to anticipate and supply it. There is need, however, for improvement in all our fixtures, especially that part which connects with the waste pipes, also the hanging, that is the arrangement or lack of arrangement for hanging fixtures to the wall. The waste and overflow of all fixtures need considerable change to make them sanitary. The opportunity is, therefore, before anyone who will apply himself to this development. Much money, thought, 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 fixtures, and then to perfect them. To these manufacturers is due the beautiful design, stability, and perfect sanitary material which make up our plumbing fixtures of today.

CHAPTER II

The Use and Care of the Soldering Iron. Fluxes. Making Different Soldering Joints

The Soldering Iron.—The soldering iron is one of the first tools a plumber has to master. This tool is sometimes called a “copper bit” as it is made of copper; and so throughout this book the words “soldering iron,” “copper bit,” “iron,” and “bit” are used synonymously. There are several different-shaped irons in common use today, but an iron shaped like the one in Fig. 13 is the one for use in the following work. Take the iron as it is purchased, having a wooden handle and the copper exposed on pointed end. Before it can be used the point must be faced and tinned. To do this, proceed as follows:

  1. First, heat the iron on the furnace.
  2. Second, place in vise and file the four surfaces of the point.
  3. Third, run a file over edges and point.
  4. Fourth, heat the iron until it will melt solder.
  5. Fifth, put 6 or 8 drops of solder and a piece of rosin the size of a chestnut on an ordinary red brick. (This rosin is called a flux.)
  6. Sixth, take the hot iron and melt the solder and rosin on the brick.
  7. Seventh, rub the four surfaces of the point of the iron on the brick keeping the point in the melted solder.

Fig. 13.—Copper.

The solder will soon stick to the copper surfaces and then the iron is ready for use.
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-ammoniac, or dip the hot iron in reduced muriatic acid, then rub the stick of solder on the iron. The use of muriatic acid in tinning the iron is not recommended. In the first place, it is not always possible to carry it, and in the second place it eats holes in the surface of iron, which makes it necessary to file and smooth the surfaces again. The constant use of muriatic acid on the copper soon wears it away and makes it unfit for use. Rosin is easily carried and applied and is by far the best to use in regular work.
