Book excerpt: Excerpt from Cyclopedia of Heating, Plumbing and Sanitation, Vol. 1 of 4: A Complete Reference Work on Plumbing, Gas Fitting, Sewers and Drains, Heating and Ventilating, Steam Fitting, Chemistry, Bacteriology and Sanitation, Hydraulics, Water Supply, Electric Wiring, Mechanical Drawing, Sheet Metal Work, Etc Lead has unequaled merit for plumbers' use in specific instances; and if the trade has suffered by injudicious substitution of other material during its rapid evolution in recent years, time will adjust the error as the fitness of lead becomes apparent. For service lines in the ground, no other material lasts longer or gives more satis faction than lead, provided the use of lead is safe with the particular water which flows through it. For cold - water lines inside buildings, it answers well. Wood tanks properly lined with lead are, in many cases, the best for indoor storage. Lead pipe is not self-supporting in any position, in the sense that iron or 'brass may be considered so; and the providing of reason ably permanent support for lead work is an expensive item. Lead pipe costs more than iron or brass, in every case; and the cost increases proportionally with the extra weight necessary for all but very light pressures; while ordinary merchant's iron pipe, or seamless brass pipe of iron-pipe size, will withstand the pressure of any municipal or private supply in America. Lead does not serve well for hot water. The contraction while cooling appears not to equal the expansion from heating; hence the pipe deteriorates at the hottest points, usually showing weakness first near the reservoir in the kitchen, especially at bends, and finally crystallizing beyond repair at those points. So much trouble has been experienced with stove and range connections of lead, that lead pipe for this purpose has been entirely abandoned. The wish to install something better suited than lead for hot-water service, is in large measure responsible for the general adoption of other material. Hot and cold supply lines that are dissimilar in material, in diameter, in joints, and in fastenings, are so unsymmetrical and outof harmony in every way that no mechanic is willing to install them for a slight real or fancied betterment.
