RPZ assemblies use two independently acting check valves separated by a pressure differential relief valve, providing the highest level of mechanical backflow protection available. This unit is sized for 1.5-inch pipe and is intended for commercial, industrial, and municipal plumbing applications where high-hazard backflow protection is required. Licensed plumbers and backflow prevention specialists are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe 112-975XL is suited for installation on commercial irrigation systems, industrial process lines, boiler feed connections, and other high-hazard cross-connection points where local codes mandate RPZ-level protection. The NP designation indicates this assembly is supplied without unions, allowing installers to specify their own end connections. It is appropriate for above-grade mechanical room installations and outdoor vault installations where access for annual testing is maintained.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduced pressure zone design provides high-hazard backflow protection against both backpressure and back-siphonage\u003c\/li\u003e\n  \u003cli\u003e1.5-inch pipe size suits a wide range of commercial and industrial service lines\u003c\/li\u003e\n  \u003cli\u003eNo-unions (NP) configuration allows field selection of end connections\u003c\/li\u003e\n  \u003cli\u003eTwo independent check valves with differential pressure relief valve for redundant protection\u003c\/li\u003e\n  \u003cli\u003eUPC listed (UPC: 612052040394) for code-compliance documentation\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 1.5-inch commercial and industrial 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 assembly tester in accordance with local plumbing codes and ASSE 1013 standards.
