Commonly referenced as a CK Rubber Kit, this kit provides the elastomeric components needed to restore internal sealing surfaces during routine maintenance or after inspection failure. It is compatible with 8-inch valve bodies in the 709, LF709, 2000CIV, and 909 valve families. Licensed plumbers and backflow assembly testers perform this type of repair as part of annual certification and testing programs.\u003c\/p\u003e\n\u003cp\u003eThis kit is intended for 8-inch backflow preventer assemblies installed in commercial, industrial, and municipal water supply systems where cross-connection control is required. The repair components support in-field rebuilding of check valve seats and seals, reducing the need for full assembly replacement. Typical installations are found in mechanical rooms, vault enclosures, and above-grade backflow installations serving fire suppression, irrigation, and domestic water service lines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRubber sealing components sized for 8-inch valve bodies\u003c\/li\u003e\n  \u003cli\u003eCompatible with 709, LF709, 2000CIV, and 909 Watts valve families\u003c\/li\u003e\n  \u003cli\u003eSupports in-field rebuild without full assembly replacement\u003c\/li\u003e\n  \u003cli\u003eLightweight kit at 1.05 pounds for easy transport to job site\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with WATTS 709, LF709, 2000CIV, and 909 series backflow preventer assemblies in 8-inch configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or certified backflow assembly tester in accordance with local plumbing codes and IPC guidelines. Shut off upstream water supply and depressurize the assembly fully before disassembly. Inspect all seats and internal cavities for debris or corrosion before installing new rubber components. After reassembly, perform a full differential pressure test to verify the device passes local test requirements before returning to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Compatibility\u003c\/strong\u003e: 709, LF709, 2000CIV, 909\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 98268399622\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: 887908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51233400193330,"sku":"887908","price":135.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307613868.jpg?v=1780099073","url":"https:\/\/voomisupply.com\/products\/watts-887908-rubber-repair-kit-8-in-709-lf709-909","provider":"Voomi Supply","version":"1.0","type":"link"}
