Product details
The Hayward CX250Z14A is the 1/2 in. drain plug for Star Clear filter tanks, supplied with its O-ring. It is the genuine Hayward part.
Why it leaks
The drain plug sits at the bottom of the filter and gets opened every time the tank is drained for a cartridge clean. The O-ring takes that cycling, plus season after season of chemistry and sun, and eventually flattens or splits. What you see is a slow weep at the base of the filter that never quite stops, and that no amount of extra tightening cures.
Fitting it
Hayward lists this plug across the Star Clear, Star-Clear II and Star Clear Plus cartridge filters and the Pro Grid DE separation tank, so check your model against the fits list. Go in hand tight with a lightly lubricated O-ring. Plastic threads do not forgive a wrench.
