Eliminate Water Hammer Noise In Your Sump Pump!

This valve was easy to install. Just slip over the 1-1/2" discharge pipe. My old check valve was chattering when the pump shut off. This valve closes quietly and does not chatter. My pump is quiet now. The problem was solved easily, and no more water hammer sound!” - Ricky Miller

Why Buy Our Silent Sump Pump Check Valve?

QUIET OPERATION: This check valve has a unique spring-loaded flapper that helps eliminate the water hammer noise that standard check valves produce, bringing a quiet operation to your sump pump. It comes with stainless steel clamps and Buna-N rubber couplings for quick installation. 

CLEAR BUILT: With the valve's clear body, it's easy to confirm visually that pumped contents are moving, the pipes are not clogged, and the pump in the basin is fully operational. The clamps and couplings fit 1-1/2" pipes and are within a 5-1/8" gap.

RELIABLE: It is designed to keep pumped water within the discharge pipe from falling back into the sump basin. A fully functional sump pump check valve can increase the pump's life expectancy by preventing water from being pumped twice.
