Astral 50mm Pump Check Valve (Genuine) #598770

Prevent backflow and protect your pool pump with this genuine Astral 50mm check valve. Engineered to maintain water direction and stop reverse flow when the pump is off — reducing wear on the pump seal and impeller and keeping your system primed for fast, reliable restarts.

A failing check valve causes the pump to lose prime, run dry, and work harder on every startup. Replacing it with a genuine Astral part restores correct system pressure and extends pump life.
