Reduced Pressure Principle Backflow Preventer

The 375A Reduced Pressure Principle Backflow Assembly is utilized where a potential high health hazard exists and is ideal for use when lead-free valves are required protecting against both backsiphonage and backpressure of contaminated water into the potable water supply.

With multiple options for NRS, OS&Y, and Butterfly shut-off valves, the 375A utilizes the Zurn Wilkins low headloss Compound Check and offers the lowest lifecycle costs on the market.
