{"product_id":"check-valve-cpvc-2","title":"Pentair Check Valve, CPVC, 2\"","description":"\u003cp\u003eThe Pentair 263042 is a straight bodied CPVC check valve in black for pool and spa plumbing. It passes water one direction and blocks it the other.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it is for\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWhen the pump shuts off, gravity pulls water back through the plumbing. A check valve stops that. It keeps the pump holding prime so it restarts without an airlock, and it keeps output from a chlorinator or chemical feeder from drifting backward toward equipment that should not see it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCPVC, not PVC\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCPVC is rated for higher water temperature than standard PVC. That makes it the material of choice on the discharge side of a heater, where returning water can be well above the comfort range of plain white pipe.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eA note on size\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe source information for this valve is not consistent about size. The listing title describes it as a 2 inch valve, while the product description describes it as a 2 inch to 2-1\/2 inch valve. Both readings are given above. Measure the pipe you are plumbing into and confirm the connection before ordering.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48626820251860,"sku":"PAC-56-4107","price":83.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_66cd26c9-e6f4-4f8a-8690-12c4f5bd2623.jpg?v=1788715438","url":"https:\/\/www.activepoolsupply.com\/products\/check-valve-cpvc-2","provider":"Active Pool Supply","version":"1.0","type":"link"}
