Backflow Reference Manual (3rd Edition)

The third edition of the Backflow Prevention Reference Manual continues to build on the important collaboration between the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry and International Association of Plumbing and Mechanical Officials Backflow Prevention Institute. 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 is used as the textbook for many training classes and also contains sample test questions to help prepare an individual to become a certified backflow prevention tester, surveyor or repairer.
