Built in a Y-pattern body configuration, this assembly accepts 1-1\/4 inch NPT connections and incorporates quarter-turn ball valves for fast isolation during testing or service. The bronze body construction provides corrosion resistance suitable for commercial and light industrial plumbing applications. Licensed plumbers and backflow technicians are the primary installers and testers for this type of assembly.\u003c\/p\u003e\n\u003cp\u003eThis backflow preventer is suited for commercial, industrial, and residential applications where a high-hazard cross-connection requires an RPZ-rated assembly. Common installation points include irrigation systems, fire suppression supply lines, boiler makeup water connections, and process water feeds. The 1-1\/4 inch NPT end style allows direct threaded connection to standard Schedule 40 or Schedule 80 piping. Its Y-pattern orientation helps minimize pressure drop across the assembly compared to straight-through inline configurations.\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 category requirements\u003c\/li\u003e\n  \u003cli\u003eY-pattern body lowers headloss compared to in-line RPZ configurations\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch NPT ends connect directly to standard threaded pipe without adapters\u003c\/li\u003e\n  \u003cli\u003eQuarter-turn ball valves on inlet and outlet allow rapid shutoff for annual testing\u003c\/li\u003e\n  \u003cli\u003eBronze body resists corrosion in potable water, irrigation, and light industrial service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style RPZ backflow preventer assembly for 1-1\/4 inch NPT threaded plumbing systems requiring reduced pressure zone protection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed plumber and, in most jurisdictions, tested annually by a certified backflow assembly tester. Shut off the upstream water supply and relieve system pressure before installation. The assembly must be installed in the orientation specified by the manufacturer and local authority having jurisdiction, typically horizontally with the relief port unobstructed and directed toward a proper drain. Consult local plumbing codes and IAPMO or IPC requirements for minimum clearances and test port access.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: NPT (threaded)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Pattern\u003c\/strong\u003e: Y-Pattern\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShutoff Valves\u003c\/strong\u003e: Quarter-Turn Ball Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAssembly Type\u003c\/strong\u003e: Reduced Pressure Zone (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: 975XL2-H 1-1\/4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILKINS","offers":[{"title":"Default Title","offer_id":51525378834738,"sku":"975XL2-114","price":1807.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc977edf00f5916495ed4d78da719080.jpg?v=1785472206","url":"https:\/\/voomisupply.com\/products\/wilkins-975xl2-h-1-1-4-rpz-backflow-preventer-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
