Zoeller 3" Quiet Check Valve

Standard check valves may produce a slamming sound when the water flow reverses in the discharge pipe after a pump stops. This is commonly referred to as water hammer. If you’d like to reduce water hammer, the Quiet Check Valve is a perfect solution. Like any good check valve, it also protects your pump by providing reliable backflow prevention. This quiet check valve offers the features provided in a standard check value with the addition of a hinged, spring-loaded flapper. This mechanism makes the flapper fully close against the fluid flow as the pump shuts down. Rapid closure against pressure before any flow reversal can occur eliminates the noise caused by hydraulic shock. Designed for full flow with a clog-resistant design, it can be installed in a vertical or horizontal orientation. The solvent-weld ends on the quiet check valve make it easy to install.
