{"product_id":"union-check-vlv-swing-spring","title":"SuperPro 1 Inch Swing-Spring Clear Check Valve with Unions, 0.5 lb Slip x Slip","description":"\u003cp\u003eThe SuperPro SP0823-10C is a 1 inch swing check valve with a clear body, unions on both ends and a 0.5 lb spring. Both connections are slip sockets, so it solvent welds into 1 inch pipe.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat a check valve is for\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt lets water move one way and stops it coming back. On a pool that is the difference between a pump that holds its prime and one that drains back to the pool every time it shuts off, and on a system with a heater or a chlorinator it keeps chemically treated water or hot water from migrating back where it does not belong.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSwing and spring\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe swing design pivots the flapper out of the flow path when the valve is open, which keeps the restriction low compared with a valve that makes the water turn. The 0.5 lb spring assists the close, so the flapper seats promptly rather than slamming when flow drops.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eServiceable, and visible\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe unions let the valve body come out without touching the glued pipe, and the clear body lets you confirm the flapper is doing its job. Between the two, a suspect check valve is quick to diagnose and quick to change.\u003c\/p\u003e","brand":"Magic Plastics Inc","offers":[{"title":"Default Title","offer_id":48634404995284,"sku":"SPG-56-1808","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_f5cef1f0-d586-4c73-b7f1-ef20a994d469.png?v=1788829195","url":"https:\/\/www.activepoolsupply.com\/products\/union-check-vlv-swing-spring","provider":"Active Pool Supply","version":"1.0","type":"link"}
