PumpSpy “Silent” Clear Sump Pump Check Valve 1-1/2 in


30 in stock

Engineered to allow for maximum flow from your sump pump. PumpSpy check valves prevent the water that remains in the sump discharge pipe from falling back into the sump pit. This avoids pumping the same water twice, extending the life of your pump. Features Clear valve body so that water movement is visible, making it easier to verify that your sump is flowing properly and the valve is seating when closed. The unique spring-loaded flapper eliminates the nuisance water hammer noise of standard check valves. Durable ABS Construction for years of Service and Reliability. 1-1/2” Buna-N rubber couplings for connecting the check valve inline with 1-1/2” sump pump discharge pipes. All Check Valve connections feature 100% stainless steel hose clamps to prevent rust and corrosion, and to provide a secure and leakproof connection.
