957
Reduced Pressure Valve Assembly Backflow Preventers Sizes: 2½ - 10Inch (65 – 250mm)
Series 957, 957N, 957Z Reduced Pressure Valve Assembly Backflow Preventers are designed to prevent the reverse flow of liquids in a plumbing system due to backpressure or backsiphonage where there is a potential health hazard. Compact design and lightweight stainless steel construction (70% lighter than traditional designs) makes installation easier and faster. Groove connections also ease installation and pipe alignment. A variety of shutoff valve options are available.
Series 957 is also available with SentryPlus™ Alert technology to detect catastrophic relief valve discharge that could potentially cause flooding, and issue a multi-channel alert (call, email, text) to selected users so they can take action to avoid potentially costly flooding.
