It lets the feed line push product into the flowing water and it stops that water, at system pressure, from traveling back up the small tubing toward the feeder or the pump. If it stops sealing, pool water gets into places that were never meant to see it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eService life\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis valve sits at the point of highest chemical concentration anywhere on the system, so it wears. Treat it as a scheduled replacement during routine service and it will not be the part that shuts a system down unexpectedly.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48627759349972,"sku":"HAY-451-2048","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/cax3511_injection_checkvalve.jpg?v=1788727783","url":"https:\/\/www.activepoolsupply.com\/products\/hayward-cax-3511-injection-check-valve","provider":"Active Pool Supply","version":"1.0","type":"link"}
