PVC solvent-weld with union check valve for reduced water hammer or quieter operation in your plumbing system

Find Nearest Distributor

A standard check valve may produce a sound when the water flow reverses in a discharge pipe after a pump stops. If you’d like your pump to stop with reduced water hammer or a quieter operation, the Quiet Check Valve from Zoller Pump Company offers a perfect solution. It can also help protect your pump by providing reliable backflow prevention.

This quiet 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.

The PVC solvent weld with a union check valve offers high performance in plumbing systems. Designed for full flow with a clog-resistant design, it allows horizontal and vertical usage without requiring threading. With compression end fittings, the construction provides incredible durability, while solvent-weld ends with unions allow for easy installation below a basin cover.
