PumpSpy Threaded Quiet Sump Pump Check Valve with 100% Stainless Steel Clamps Included – Threads Directly into the Pump’s 1-1/2″ NPT Discharge to Connect it to a 1-1/2″ Pipe – Model CV-150T

The PumpSpy Threaded Quiet Sump Pump Check Valve threads immediately into a pump’s 1-1/2″ NPT discharge to connect it to a 1-1/2″ pipe and is engineered to allow for maximum drift from your sump pump. Works with any pump containing a 1-1/2″ NPT discharge. The unique spring-loaded flapper on our sump pump check valve removes the water hammer noise of standard check valves for silent operation. No more sudden noises that disrupt your way of life or sleep. With this check valve, water hammer noise will be a nuisance of the past! The usage of 100% stainless steel hose clamps prevents rust and corrosion for a safe, leak-proof connection. The durable ABS construction of the check valve brings reliable performance so that they can last for a very long time. The pre-drilled weep hole of our pump sump check valve removes the air lock that may occur in bottom suction pumps. Our “full-drift” 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.
