{"product_id":"air-relief-o-ring","title":"Waterway Clearwater II Air Relief O-Ring","description":"\u003cp\u003eThe Waterway 805-0136 is the genuine air relief o-ring for Clearwater II cartridge filters. It is the small seal that sits under the manual air relief valve on the filter lid.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eEvery cartridge filter needs a way to bleed trapped air after the lid goes back on. The manual air relief does that job, and this o-ring is what keeps the valve from leaking once the air is out and the tank is under pressure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIf the relief valve drips or sprays when the pump starts, and closing it further does not stop it, the o-ring has hardened or taken a set. It is inexpensive enough that most techs replace it whenever the filter is opened for a cartridge clean. Seat it with a silicone based lubricant, not a petroleum grease, which will swell the rubber and cause the same leak again.\u003c\/p\u003e","brand":"Waterway","offers":[{"title":"Default Title","offer_id":48633672073428,"sku":"WWP-051-0136","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_51f48a2e-c966-431c-ac79-da67b5751b0e.jpg?v=1788808573","url":"https:\/\/www.activepoolsupply.com\/products\/air-relief-o-ring","provider":"Active Pool Supply","version":"1.0","type":"link"}
