Plumbing is a complex and vital system in any home, and mistakes can be costly. With this in mind, master plumber Cauldwell (Safe Home Wiring Projects) addresses all aspects of home plumbing, focusing on safety and code compliance throughout. The intense depth of coverage spans from piping materials to fixtures. Well drilling and maintenance chapters make this book particularly valuable, especially to rural areas. Cauldwell's wry comments (on, e.g., the narrow sizes of toilet seats and awkward past plumbing mistakes) give the text flavor. The material and its organization are superior. Way more than needed for casual projects, but for a complete understanding of all plumbing systems, this book is invaluable; highly recommended for all collections.
