It is the genuine Pentair part, and it is what you order when the valve itself is sound but the flapper inside has stopped sealing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat a failed check valve looks like\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA check valve is supposed to pass water one way and hold it the other. When the flapper wears, warps or tears, water runs backwards through the line. On a pump return that shows up as lost prime after every shutdown; on a solar or heater loop it shows up as water draining out of the panels or the heat exchanger.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy rebuild instead of replace\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe valve body is CPVC and it is glued into the plumbing. Replacing it means cutting pipe and rebuilding a section of the pad. This kit renews the working parts so the body stays where it is, which is a much shorter job and a much smaller bill.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48627951960276,"sku":"PAC-561-1002","price":100.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/270119Z_pentair_flapper.jpg?v=1788730783","url":"https:\/\/www.activepoolsupply.com\/products\/pentair-2-50-3-cpvc-check-valve-rebuild-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
