MODERN methods of sanitation as well as the complications introduced by the development of the city building, have in late years placed responsibilities on the professional plumber far beyond the ability to wipe a joint and solve the ordinary drainage problems of a frame dwelling. The successful plumber must not only be a good workman who knows where to use lead pipe and where to use brass and iron, how to properly place the drains and the piping, and how to properly mount the fixtures; but he must be versed in the principle of sanitation, the proper location of tanks, the sizes of water and drainage pipe, the laws of water flow, pressure, and many other questions involved in giving to any dwelling, office building, or factory, adequate and well designed water and drainage systems.

This means that the up-to-date plumber must really be a sanitary engineer and it is to give the practical man authoritative information on these subjects that this little volume has been published. The article covers a discussion of the latest types of plumbing fixtures; house water supply with practical examples and diagram showing methods of installation; pumps and service pipes; connections for hot-water systems with temperature regulators; filters and water motors; gas piping and meter reading; sewage disposal and purification; sewer construction; and the description of a complete house drainage system. The authors are both men of reputation and long experience in practical plumbing work, and it is their hope as well as that of the publishers that this volume will prove of distinct value to the professional plumber as well as to those who are only interested in keeping in touch with modern progress.
