{"product_id":"hayward-clx220ea-cl-series-check-valve-with-inlet-fitting-adapter","title":"Hayward CLX220EA CL-Series Check Valve with Inlet Fitting Adapter","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eEngineered as an OEM check valve and inlet fitting adapter assembly for Hayward's CL-Series offline chlorine and bromine feeders, the Hayward CLX220EA performs two essential roles in one component. The inlet fitting adapter connects the water supply line to the chlorinator's inlet port, while the built-in ball check valve prevents concentrated chlorinated water from backflowing into the rest of the pool's plumbing — particularly into heaters and heat exchangers — once the circulation pump shuts off. When a check valve fails or degrades, highly concentrated chlorine can travel backward through the lines during pump-off cycles, causing severe corrosion damage to heat exchangers and other sensitive pool equipment over time. The CLX220EA is compatible with Hayward chlorinator models CL100, CL110, CL110BR, CL200, CL220, and CL220BR, making it a small but critical component that ultimately protects some of the most expensive equipment installed 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 class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eOEM Two-Component Assembly:\u003c\/strong\u003e Hayward manufactures the CLX220EA to exact OEM specifications so the check valve and inlet fitting adapter integrate cleanly with CL100, CL110, CL110BR, CL200, CL220, and CL220BR offline chlorinator and brominator models, delivering the precise fit and consistent sealing required at the chlorinator's inlet connection.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eAutomatic Ball Check Valve Action:\u003c\/strong\u003e When the pump shuts off, the internal ball check valve closes automatically and blocks highly concentrated chlorinated or brominated water from migrating backward through the plumbing, an important safeguard that protects heaters, heat exchangers, and other downstream pool equipment from the chemical corrosion that follows concentrated chemical exposure.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eProtects High-Value Heater Equipment:\u003c\/strong\u003e Failed or worn check valves are one of the most overlooked root causes of premature heat exchanger corrosion in pool systems, and installing a fresh OEM CLX220EA is a relatively low-cost preventative measure that helps extend the service life of dramatically more expensive heater and heat pump equipment downstream of the chlorinator.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eIncludes Adapter, Valve, and Compression Nut:\u003c\/strong\u003e The CLX220EA ships as a complete assembly containing the check valve, inlet fitting adapter, and compression nut, allowing the chlorinator's inlet connection to be replaced fully in one purchase without the hassle of sourcing fittings and hardware separately from multiple parts catalogs.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eFits the Hayward CL-Series Lineup:\u003c\/strong\u003e Compatible with the Hayward CL100, CL110, CL110BR, CL200, CL220, and CL220BR offline chlorine and bromine feeders, the CLX220EA covers the bulk of Hayward's residential offline chlorinator installations, making it one of the more universally applicable replacement parts in the Hayward chlorinator catalog.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":55150145143075,"sku":"CLX220EA","price":17.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0914\/0987\/5235\/files\/wpmHaywardCLX220EACL-SeriesCheckValvewithInletFittingAdapter.jpg?v=1779746773","url":"https:\/\/wholesalepoolmart.com\/products\/hayward-clx220ea-cl-series-check-valve-with-inlet-fitting-adapter","provider":"Wholesale Pool Mart","version":"1.0","type":"link"}
