In February 2003, the International Codes Council released the 2003 International Plumbing Codes; for the first time all plumbing codes are offered as one. Some regional differences remain, but now one agency will offer and maintain plumbing codes for the entire country. This book delves into both the new code's content and intent, explaining the code and its usage in real-world terms, with examples that make learning easy. This approach helps designers and installers minimize cost, and results in more profitable jobs installed in full compliance with code requirements. It digests and interprets the 2003 International Plumbing Codes. It is heavily illustrated with charts, photos, and tables. It includes examples and side-bars to simplify code requirements.
