This "one-stop" resource identifies the significant changes that occurred between the 2003 and 2006 Editions of the International Plumbing Code (R), the International Mechanical Code (R), and the International Fuel Gas Code (R) so that users can comply with the requirements and implement the changes in a cost effective manner. A must- have for professionals who need to quickly understand Code updates in their particular profession, this outstanding resource provides the same level of knowledge as the International Code Council (R) (ICC) commentaries that readers have come to rely on, in one convenient location for plumbing, mechanical, and fuel gas applications. Not only does this format assist users in identifying the specific Code changes that have occurred in their professions, it also aids designers, Code officials, and installers in comparing the previous Code language to the new text, and most importantly, fosters an understanding of why the Code changed.
