White Quiet Check Valve

When a sump pump is pumping water up that water weight sits on the check valve. When that water is being pumped the valve opens and allows the water to be evacuated. When the pump shuts off, and depending on how much water weight there is, the check valve could slam shut causing a loader than desired thud. This check valve, like the clear version, has a spring in the check valve that softens the closer of the valve. This spring aids the check valve's quieter operation.
