The Basement Watchdog 1.5 in. rubber-booted check valve is both quiet and creates a more stable installation. The check valve is spring loaded and has an angled seat to muffle the loud clunk after the pump turns off. The BW-CVK15 allows the pump discharge pipe to be seated inside the ends of the valve itself, taking the pressure off the couplings for a clean and secure connection with no wobble or lean. This check valve can be used in either horizontal or vertical (solid free) installations, is compatible with schedule 40 and 80 PVC, and works in both sump and effluent applications.

If you are a person that likes to keep to name brand items, go ahead make your purchase. Works great.I have installed these, and they work fine. If you have a day or two to wait this is the product for you.On the other hand, Everbuilt feels heavier, has better plastic and rubber, runs the same price, and you can get it from HD, or LOWES... no wait time.
