9.5 worth the money
Main highlights

QUIET OPERATION: Our sump pump check valve has a unique spring-loaded flapper that helps eliminate the water hammer noise that standard check valves produce. The water hammer noise occurs when the discharged water slams the check valve flapper down. This silent check valve can bring a quiet operation to your sump pump.
KEEP WATER OUT: This check valve 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 pump life expectancy by preventing water from being pumped twice.
INCLUSIONS: Our silent sump pump check valve comes with stainless steel clamps and Buna-N rubber couplings for quick installation. The clamps and couplings fit a 1-1/2" Schedule 40 pipe. Fits within a 5-1/8" gap.
CLEAR VALVE BODY: This check valve will provide visibility to water movement. With the valve's clear body, it's easy to visually confirm that pumped contents are moving, the pipes are not clogged, and the pump in the basin is fully operational.
ABOUT US: PumpSpy provides sump pump systems that help eliminate the unknowns of a sump outage and prevents costly damage. We also offer Smart Sump Pump Systems that automatically track incoming data and check that a sump pump is working properly.
