2″ Flexible Coupling Sump and Sewage Check Valve

2″ Flexible Coupling Sump check valves allow for the unrestricted flow of water up and out through the pipes. When the pump turns off, it prevents the flow of water back through the sump pump. Feature a full port valve design. The flapper opens 100% and is seated on a 15° angle to reduce water hammer when the pump shuts off. This also prevents debris from building up or getting caught, ensuring proper seating. This check valve features a blow out proof nylon reinforced gasket design.
