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 third edition of IAPMO's Backflow Prevention Reference Manual.
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.
"IAPMO and the UA brought together the best minds in the industry to develop and improve the third edition of the Backflow Prevention Reference Manual," said Bruce Pfeiffer, IAPMO president. "The resulting publication contains the technical resources and expertise needed by those responsible for protecting our water supply from cross-connections and contamination."
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.
Vice President of the IAPMO Backflow Prevention Institute Sean Cleary points out: “This manual contains the information needed by not only certified testers, but also by plumbing inspectors, design professionals, building officials and engineers to ensure that the proper protection is specified, installed, tested and maintained. I encourage everyone in the industry to use this important tool.
3rd Edition IAPMO Backflow Prevention Reference Manual
The unique, 300-page Backflow Prevention Reference Manual contains illustrations in real-world field settings and can be used by regulatory agencies as a guide to determine what type of valve can be used in a particular case. With information on the history of backflow prevention as well as chapters written from the regulatory perspective, Backflow Prevention Reference Manual is an important resource for system designers, urban planners, and utility companies-professionals "on both sides of the water meter".
This text, originally published in 2006, updated in 2011, and now again in 2016 has become the most used reference manual in the training and certification of backflow assembly testers, repairers, surveyors, and others working in all phases of the cross-connection control industry.
