This kit provides the elastomeric sealing components needed to restore proper check valve function during scheduled maintenance or after a failed inspection. Licensed plumbers and fire protection contractors rely on this type of kit to return backflow preventers to service without replacing the entire assembly. At 8 inches, this kit is sized for large-diameter commercial and industrial installations where maintaining water supply integrity is required by code.\u003c\/p\u003e\n\u003cp\u003eThis repair kit is intended for use in commercial, industrial, and municipal water systems where large-bore backflow preventers are installed. It is commonly used during annual testable backflow preventer maintenance, after a failed third-party inspection, or as part of a preventive maintenance schedule. The 8-inch size makes it appropriate for high-flow service lines, fire suppression supply connections, and similar large-diameter applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRubber sealing components restore second check function in supported backflow preventer assemblies\u003c\/li\u003e\n  \u003cli\u003eSized at 8 inches for large-diameter valve applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with 909, LF909, 4000CIV, and 5000CIV series assemblies\u003c\/li\u003e\n  \u003cli\u003eSupports field repair without full assembly replacement\u003c\/li\u003e\n  \u003cli\u003eOEM-style fitment for consistent sealing performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with WATTS 909, LF909, 4000CIV, and 5000CIV series backflow preventer assemblies in the 8-inch size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or certified backflow prevention tester.
