Quiet Operation and Supreme Stability

The PS-CVKSRRU20 check valve’s unique design muffles the noise from the sump pump turning on and shutting off. In addition, a pump’s discharge pipe can be seated inside the PVC section of the check valve, taking pressure off the couplings for a clean installation. No more leaning or wobbling like you see from using a standard booted check, which can cause it to pop off or the rubber to give way after years of pressure on the connections.
