Backflow is defined as the reverse flow of contaminated or undesirable substance into the potable water supply. Installing a backflow preventer can protect the water supply from this very serious type of situation. This product guide includes information on Watts’ complete line of backflow prevention devices. Code Requirements All major plumbing code bodies address protection against backflow. All potential or existing cross-connections must be protected from backflow by installing a proper backflow prevention device. Consult your national and local plumbing code authorities for more specific information on your code requirements. Backflow Definitions 757 OSY Backpressure: Pressure, higher than the supply pressure, caused by a pump, elevated tank, boiler, or other means that can cause backflow. Backsiphonage: Backflow caused by negative or reduced pressure in the supply piping. Cross-connection: A connection or potential connection between any part of the po- LEAD FREE table water system and another environment where undesirable substances could enter the potable water system. Contaminated or undesirable substances can include gases, Backflow prevention has critical liquids, or solids, such as chemicals, waste products, steam, water from other sources implications in potable water supply (potable or non-potable), or any other matter that can change the color of or add odor systems.

Designed to eliminate valve vault entry requirements of OSHA confined Space Ruling 29CFR 1910.146. Single source Watts Regulator warranty of the enclosure, the backflow preventer, and the heat source. Allows for the installation of the backflow preventer “at the service connection” in accordance with AWWA Standards. Is specifically designed to meet NFPA guidelines. The enclosure provides freeze protection to maintain the water supply to the property’s fire protection system. (NFPA 3-3.1.8 and 3.6.1.3.2). Strategically placed doors provide access to the backflow prevention assembly for testing and repair without removal of the entire unit. An economical alternative to expensive retrofit installations. Eliminates potential drainage constraints in existing equipment rooms. Saves valuable floor space. Standardly furnished with thermostatically controlled heat source for freeze protection down to -30°F. Contains no structural wood or particle board for long life. Easy installation aluminum enclosures feature interlocking panels which eliminate the use of screws during assembly. Can be temporarily removed for replacement of the backflow preventer without the need for replacement of freeze protection services. ASSE 1060 Certified (Consult factory for approved models)
