PVC Double Union Clear Check Valve

Check valves allow single-directional water flow and are used to prevent back siphoning. They are commonly used on return pump outputs to prevent water overflowing the sump in the event of a power outage, pump failure or maintenance.

These check valves feature true union fittings on each end for easy cleaning or replacement.

Designed to fit Schedule 40 pipe and fittings of the same size.
