Troubleshooting a Zurn Wilkins 375A Reduced Pressure Principle Assembly

Watch as our team walks you through diagnosing and maintaining a large 375A reduced pressure principle backflow preventer.
The 375A reduced pressure principle is used where a potential high-risk health hazard exists and is ideal for use when lead-free valves are required. Its design protects against both backsiphonage and backpressure of contaminated water into the potable water supply. The 375A includes a lightweight, grooved, epoxy-coated ductile iron valve body eliminating exposure to corrosion. 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.
