摘要

In collaboration with the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry of the United States and Canada (UA), the International Association of Plumbing and Mechanical Officials (IAPMO) is pleased to announce the release of the third edition of IAPMO's Backflow Prevention Reference Manual. Where the second edition, published in 2011, merged two of the industry's most relied upon training manuals - the first edition of IAPMO's Backflow Prevention Reference Manual and the UA's Cross Connection Control Manual - this new release is updated to the latest editions of the plumbing, mechanical, and fire protection codes and standards. It also features expanded chapters with regard to non-testable devices and methods, and improved, updated, and expanded testing/repair/troubleshooting information reflecting the latest products and procedures.
