Principles And Practice Of Plumbing | by John Joseph Cosgrove

In preparing the manuscript for this book, the author's sole object has been to systematize and reduce to an exact basis, the principles that underlie the practice of plumbing. The necessity for accurate rules and formulas, instead of the empirical methods formerly employed, was often and forcibly brought home to the author when designing plumbing installations for large buildings. The scarcity of scientific information on this important branch of sanitation was quite marked. No book had ever been published that indicated the best kind of material to use for a given purpose, that told how work should be designed and installed to be perfectly sanitary, and that showed how to proportion the various parts with relation to the whole, so that a plumbing system designed and installed according to the text would give perfect service.
