It is also listed by Pentair as the replacement check valve diverter kit for 2 way and 3 way valves, and both descriptions refer to this same part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it fixes\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA check valve exists to let water go one way and stop it coming back. The flap is the moving piece that does the stopping, and it takes a hit every time the pump starts and stops. When it tears, stiffens or stops seating, water runs backward when the system shuts down and the pump can lose prime.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eRepair over replacement\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA flap kit lets the valve body stay glued in the plumbing. That turns what would be a cutting and repiping job into an internal parts change, which is why it is worth keeping the part number to hand.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48627345588436,"sku":"PAC-561-1001","price":41.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_90856e23-4cb5-4471-8e21-fbd5c70fc892.jpg?v=1788722716","url":"https:\/\/www.activepoolsupply.com\/products\/check-valve-flap-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
