Fernco Sump Pump Check Valves allow unrestricted water to flow through the pipes, but when the pump turns off, the water does not flow backwards into the sump pump, which would typically cause damage. Sump Pump Check Valve is a full-flow, flapper design that eliminates back-flow and wear on pipe. Durable, thermoplastic body. For 1-1/4 in or 1-1/2 in pipe to 1-1/4 in or 1-1/2 in pipe.
