2in Durable Transparent Pool Check Valve

This durable pool check valve measures 2 inches (60.2 mm) at its nominal interface and weighs about 727 g (25.6 oz). Built from ABS+PVC, it offers excellent resistance to pool chemicals and environmental wear. Its transparent construction allows users to monitor internal operation directly — particularly the baffle’s sealing response — without dismantling the unit. It is intended for mounting at the water pump outlet to enforce unidirectional flow and prevent backflow-related impeller damage. Proper setup involves confirming pipe-to-valve diameter match, performing a manual baffle rebound test, switching off the pump, clearing debris from the valve interior, aligning the engraved flow arrow with actual water direction, and cleaning all sealing surfaces before final assembly.
