Clear Check Valve – 1.5in Slip – AZ-CSCV1.5IN

Description

The swing check valves, when placed inline before an external pump, will always allow easy water flow until the pump is turned off or the electricity goes out. Once the pump stops suction, the swing check valve closes with a watertight seal keeping the water from back flowing. A check valve is a must when using an external pump above water level.
