EasyPro 1-1/2" Coupling Check Valve Assembly

These check valve assemblies are used inside Pro-Series skimmers to bring the flow of water from a Spirit Pump up to the outlet hole in the back wall of the skimmer. In an ideal world all pumps would have their outlet at the same height but that is not the case so various height assemblies are needed. Each assembly includes a check valve which keeps the plumbing line full of water even when the pump is off.
