It protects potable water systems against both backsiphonage and backpressure, preventing contaminated water from entering the drinking water supply. The assembly incorporates a differential pressure relief valve between two independently operating check valves, maintaining a lower pressure zone that vents to atmosphere if either check fails. Licensed plumbers and backflow prevention specialists install and test this type of assembly in compliance with local cross-connection control regulations.\u003c\/p\u003e\n\u003cp\u003eThe 975XL3-112 is designed for installations where a health hazard exists at the point of connection  -  including commercial irrigation systems, boiler feed lines, chemical injection points, and industrial process connections. It is suited for both new construction and retrofit applications on 1.5-inch potable water lines requiring full RPZ-level protection per local plumbing authority requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free construction meets safe drinking water act requirements for potable water contact\u003c\/li\u003e\n  \u003cli\u003eReduced pressure zone design provides the highest level of backflow protection for health-hazard-rated cross-connections\u003c\/li\u003e\n  \u003cli\u003eProtects against both backsiphonage and backpressure conditions\u003c\/li\u003e\n  \u003cli\u003e1.5-inch pipe size fits standard commercial and light industrial water service lines\u003c\/li\u003e\n  \u003cli\u003eDesigned for field testing and maintenance per ASSE 1013 standards applicable to RPZ assemblies\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 1.5-inch potable water supply piping where reduced pressure zone protection is required by code.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed plumber or certified backflow prevention assembly tester, as required by most jurisdictions under local plumbing codes and cross-connection control programs. Shut off the water supply and relieve system pressure before installing or servicing the assembly. The unit must be installed in the orientation specified by the manufacturer, typically horizontal with the relief valve port facing down and unobstructed. After installation, a certified tester must perform an initial field test and submit results to the local water authority before the assembly is placed in service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAssembly Type\u003c\/strong\u003e: Reduced Pressure Zone (RPZ) Backflow Preventer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead-Free\u003c\/strong\u003e: Yes\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: 975XL3-112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILKINS","offers":[{"title":"Default Title","offer_id":68094574297394,"sku":"975XL3-112","price":1359.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/454045306a46979addfe4b3475991db7.jpg?v=1793248268","url":"https:\/\/voomisupply.com\/products\/wilkins-975xl3-112-reduced-pressure-zone-assembly","provider":"Voomi Supply","version":"1.0","type":"link"}
