{"product_id":"diverter-spider-gasket","title":"Waterway Diverter Spider Gasket","description":"\u003cp\u003eThe Waterway 711-1910B is the diverter spider gasket, also called the valve seat gasket, for Waterway filter valves. It is molded in white rubber with a four spoke pattern.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe gasket measures 5-1\/4 inches across the outside with a 15\/16 inch inside hole. Each of the four spokes is 3\/8 inch wide. Those figures are worth checking against the gasket you are removing, since spider gaskets look alike across brands and only the exact one seals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat goes wrong\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe spider gasket is what the rotating diverter presses against to keep the valve ports separated. When it flattens, tears at a spoke, or hardens until it no longer stands proud of its groove, water crosses between ports. The symptoms are familiar: water going to waste while the valve is set to filter, backwash that never quite stops, or a filter that will not build pressure. Replacing the gasket restores the seal the whole valve depends on.\u003c\/p\u003e","brand":"Waterway","offers":[{"title":"Default Title","offer_id":48626590548180,"sku":"WWP-061-1910","price":25.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_817b661d-86a5-4cde-b89f-db2b25031a6e.gif?v=1788712773","url":"https:\/\/www.activepoolsupply.com\/products\/diverter-spider-gasket","provider":"Active Pool Supply","version":"1.0","type":"link"}
