Thoroughly updated with the assistance of seventeen master plumbers, the third edition of Plumbing Technology: Design and Installation introduces readers to all aspects of the commercial and residential plumbing trade, including home building. An excellent study guide for plumbers preparing to pass the "master plumber" exam, this edition features updated coverage of all current plumbing codes. Each unit of Plumbing Technology, 3rd Edition also contains new and improved summaries, plus "Test Your Understanding" quizzes (with answers in an appendix), to clarify and reinforce more difficult concepts. In addition, projects located throughout the book provide opportunities for hands-on plumbing practice and actual application of concepts. As such, readers gain an understanding of both the "why" and the "how" of plumbing design and installation.
