The air release valve is what lets that air out on startup, and it is the first thing a tech opens after priming the pump. Because it spends its life at the top of a pressurised tank, the o-ring in it takes a beating from chlorine and heat, and it hardens long before anything else on the filter gives up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment and size\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe valve is listed for the Waterway Pro Clean cartridge filters and the Clearwater II filters.
