It supplies the elastomer components needed to restore proper sealing and flow-check function in 2.5-inch through 4-inch C400, C500, 957, and LF957 RPDA assemblies, and in 2.5-inch through 3-inch M400 and M500 assemblies. EPDM material provides reliable resistance to water service and is the correct compound for potable-water and general plumbing applications. Plumbers and backflow prevention specialists use this kit during scheduled maintenance or after a failed annual test to return a device to service without replacing the full valve body.\u003c\/p\u003e\n\u003cp\u003eThis kit is used in commercial and residential plumbing systems where reduced-pressure or double-check backflow preventers are installed to protect potable water supplies. It is suited for retrofit repair during annual inspection cycles required by most municipal water authorities. Typical installation locations include mechanical rooms, irrigation systems, and fire-line service entries where Watts C400, C500, 957, LF957 RPDA, M400, or M500 assemblies are present in the 2.5-inch to 4-inch size range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEPDM elastomer construction for potable-water compatibility\u003c\/li\u003e\n  \u003cli\u003eFits first check valve position in C400, C500, 957, and LF957 RPDA assemblies sized 2.5 to 4 inches\u003c\/li\u003e\n  \u003cli\u003eAlso compatible with M400 and M500 assemblies sized 2.5 to 3 inches\u003c\/li\u003e\n  \u003cli\u003eDesigned for use during annual backflow preventer maintenance and inspection\u003c\/li\u003e\n  \u003cli\u003eAllows in-field repair without full valve body replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Watts C400, C500, 957, and LF957 RPDA backflow preventers in 2.5-inch through 4-inch sizes, and Watts M400 and M500 backflow preventers in 2.5-inch through 3-inch sizes, first check valve position.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or certified backflow prevention assembly tester. Shut off the upstream isolation valve and relieve system pressure before disassembling the check module. Follow the applicable International Plumbing Code and local authority having jurisdiction requirements for backflow preventer servicing. After reassembly, perform a differential pressure test to verify the device meets the required threshold before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: EPDM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Valve Sizes (C400\/C500\/957\/LF957 RPDA)\u003c\/strong\u003e: 2.5 to 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Valve Sizes (M400\/M500)\u003c\/strong\u003e: 2.5 to 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC Code\u003c\/strong\u003e: 737733021339\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WATTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7010022\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51233963901234,"sku":"7010022","price":302.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307613870.jpg?v=1780113334","url":"https:\/\/voomisupply.com\/products\/watts-7010022-first-check-valve-epdm-rubber-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
