Built with a lead free cast bronze body, it is rated for installation in residential and commercial plumbing systems where code requires high-hazard backflow protection. The 1\/2 inch nominal size with female NPT (FNPT) end connections makes it straightforward to thread into existing supply lines. Quarter-turn ball valves are integrated on both the inlet and outlet, allowing fast shutoff during testing or service without additional isolation valves.\u003c\/p\u003e\n\u003cp\u003eThis backflow preventer is suited for protecting irrigation systems, boiler makeups, chemical feed lines, and other cross-connection points where a reduced pressure principle assembly is required by the authority having jurisdiction. The compact 1\/2 inch configuration fits tight mechanical rooms and residential utility spaces. A licensed plumber or backflow prevention specialist typically installs and performs the required annual certification testing on this style of assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduced pressure zone design provides high-hazard backflow protection per ASSE 1013 assembly standards\u003c\/li\u003e\n  \u003cli\u003eLead free cast bronze body meets state and federal lead-free plumbing requirements\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch nominal FNPT end connections for direct threaded installation\u003c\/li\u003e\n  \u003cli\u003eIntegrated quarter-turn ball valves on inlet and outlet for quick field shutoff\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for residential and light commercial applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style reduced pressure zone backflow preventer for 1\/2 inch nominal FNPT threaded plumbing systems requiring high-hazard cross-connection control.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed plumber or certified backflow prevention technician in accordance with local plumbing codes and IPC cross-connection control requirements. Shut off the water supply and relieve system pressure before threading the assembly into the line. The unit must be installed in the orientation specified by the manufacturer, typically horizontal with the relief valve port facing downward, and must remain accessible for annual testing. Do not install downstream of a check valve that would prevent a required differential pressure relief discharge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Thread)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Lead Free Cast Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Quarter-Turn Ball Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBackflow Prevention Type\u003c\/strong\u003e: Reduced Pressure Principle (RPZ)\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: WILKINS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12-975XL3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILKINS","offers":[{"title":"Default Title","offer_id":51524339237170,"sku":"975XL3-12","price":606.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c2ef8d0986d34be728ae0cdd9384bf5.jpg?v=1785446419","url":"https:\/\/voomisupply.com\/products\/wilkins-12-975xl3-backflow-preventer-1-2-inch-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
