New edition includes expanded chapters on non-testable devices and methods, and improved, updated, and expanded testing/repair/troubleshooting information reflecting the latest products and procedures.

In collaboration with the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry of the United States and Canada, the International Association of Plumbing and Mechanical Officials 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.

“The third edition of the Backflow Prevention Reference Manual continues to build on the important collaboration between the UA and IAPMO’s Backflow Prevention Institute,” said Sean Cleary, vice president of BPI. “This text has become the most used reference manual in the training and certification of backflow assembly testers, repairers, surveyors, and others working in all parts of the cross-connection control industry.”

This full color, illustrated reference manual is designed to teach every aspect of backflow prevention and cross- connection control, from identifying and testing the wide variety of backflow prevention assemblies to proper selection and installation of both testable assemblies and non-testable backflow prevention devices.

The tester will be able to recognize (and properly document) the symptoms of backflow prevention assembly and device failure, and provide the knowledge needed to repair and ensure that the backflow preventer is performing within industry standards. This manual provides instruction on how to recognize degrees of hazard or potential risks to potable water systems, and whether the proper backflow prevention method, device or assembly has been correctly installed.

The manual covers the history of backflow prevention; definitions and devices; backflow prevention hydraulics; testing methods with full, detailed illustrations; an overview of gauges and test kits; trouble shooting guide; cross-connection control surveys; program development; code requirements and installation standards. The manual also contains sample test questions to help prepare an individual to become a certified backflow prevention tester, surveyor or repairer.
