{"product_id":"hayward-cl-series-check-valve-with-inlet-fitting-adapter-clx220ea","title":"Hayward CL-Series Check Valve with Inlet Fitting Adapter | CLX220EA","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Hayward CLX220EA is a genuine OEM check valve and inlet fitting adapter assembly for Hayward's CL-Series offline chlorine and bromine feeders. This two-component assembly performs two essential functions: the inlet fitting adapter connects the water supply line to the chlorinator's inlet port, and the built-in ball check valve prevents concentrated chlorinated water from backflowing into pool equipment — particularly heaters and heat exchangers — when the pump shuts off. Without a properly functioning check valve, highly concentrated chlorine can flow back through the plumbing during pump-off cycles, causing severe corrosion damage to heat exchangers and other sensitive pool equipment over time. Compatible with Hayward chlorinator models CL100, CL110, CL110BR, CL200, CL220, and CL220BR, the CLX220EA is a small but critical component that protects some of the most expensive equipment in any pool system.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eHighlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine Hayward OEM Assembly:\u003c\/strong\u003e Factory-authorized CLX220EA check valve and inlet fitting adapter manufactured by Hayward to exact OEM specifications — ensuring proper integration with CL100, CL110, CL110BR, CL200, CL220, and CL220BR offline chlorinator and brominator models.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrevents Backflow of Concentrated Chlorine:\u003c\/strong\u003e The internal ball check valve closes automatically when the pump shuts off, blocking highly concentrated chlorinated or brominated water from flowing backward through the plumbing — protecting heaters, heat exchangers, and other pool equipment from chemical corrosion damage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCritical Heater \u0026amp; Equipment Protection:\u003c\/strong\u003e A failed or degraded check valve is one of the most overlooked causes of premature heat exchanger corrosion — replacing a worn CLX220EA is a low-cost investment that helps extend the service life of far more expensive downstream pool equipment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Adapter Assembly — Ready to Install:\u003c\/strong\u003e Includes the check valve, inlet fitting adapter, and compression nut, providing everything needed for a complete, leak-free replacement of the chlorinator's inlet connection in one convenient assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroad CL-Series Chlorinator Compatibility:\u003c\/strong\u003e Fits the full range of Hayward's most widely installed offline chlorine and bromine feeders — CL100, CL110, CL110BR, CL200, CL220, and CL220BR — making it one of the most universally needed replacement parts in the Hayward chlorinator parts catalog.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":53242523713836,"sku":"CLX220EA","price":24.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/1943\/3260\/files\/sosHaywardCheckValvewithInletFittingAdapterCLX220EA.jpg?v=1779744304","url":"https:\/\/www.sospool.com\/products\/hayward-cl-series-check-valve-with-inlet-fitting-adapter-clx220ea","provider":"SOS Pool \u0026 Spa Supplies","version":"1.0","type":"link"}
