This 3/4 inch double check valve backflow preventer assembly is designed to prevent the backflow of polluted water from entering into the potable water supply due to back siphonage and or backpressure. It features a durable bronze body construction, NPT end connections, and quarter-turn ball valve shutoffs. The assembly has a compact, modular design with top entry for easy in-line maintenance and repairs, including replaceable check discs and seats. It also includes a freeze sensor with SentryPlus Alert technology to signal when ambient temperature approaches the freeze threshold, a feature often used in non-potable continuous pressure piping applications like irrigation systems. The maximum working pressure is 175 PSI
