Check Valve","description":"\u003cp\u003eThe Jandy 7305 is a spring loaded check valve with 2 in. internal and 2-1\/2 in. external ports. That dual size port means one valve fits either pipe size: 2 in. pipe glues inside the port, 2-1\/2 in. pipe glues over the outside.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy a spring check valve\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWater flows through in one direction. The moment the pump stops, the spring closes the valve so nothing drains back. That protects a heater from thermal siphoning, keeps solar panels from emptying into the pool, and stops chlorinated water from running back toward the equipment.\u003c\/p\u003e\u003cp\u003eIt is the genuine Jandy part. Replacement internal kits are available separately, and Jandy makes the same valve in 1-1\/2 in. \/ 2 in. and 2-1\/2 in. \/ 3 in. sizes if your plumbing calls for one of those.\u003c\/p\u003e","brand":"Zodiac","offers":[{"title":"Default Title","offer_id":48624970203348,"sku":"JDY-56-4084","price":74.02,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_13e092bd-f50a-48fb-be76-96a0da13fe80.png?v=1788656961","url":"https:\/\/www.activepoolsupply.com\/products\/check-valve-2-2-1-2","provider":"Active Pool Supply","version":"1.0","type":"link"}
