It protects the potable water supply against backflow from a connected system or appliance.\u003c\/p\u003e\u003cp\u003eRPZ assemblies are ASSE 1013 devices used where a cross-connection presents a high hazard, such as boiler fill lines, irrigation and process equipment. Two independent check valves with a relief valve between them discharge water to atmosphere if backflow conditions occur. This low-lead brass model is rated for 150 psi and 150°F.\u003c\/p\u003e\u003cp\u003eBefore ordering: confirm the 3\/4\" NPT connection on your piping (see the submittal sheet for thread details). The relief port discharges water during operation, so plan for an air gap and drain at the installation. Most jurisdictions require RPZ assemblies to be installed and tested by a certified tester, typically every year.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Caleffi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part #:\u003c\/strong\u003e 574050A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Reduced pressure zone (RPZ) backflow preventer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 3\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e NPT threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Pressure:\u003c\/strong\u003e 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Temperature:\u003c\/strong\u003e 150°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards:\u003c\/strong\u003e ASSE 1013\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Content:\u003c\/strong\u003e Low lead\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 8016615577907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Backflow Preventers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDocuments\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/res.cloudinary.com\/dzhpkjoqj\/Caleffi\/574050A_CALE-574050A_8016615577907_TechB.pdf\" target=\"_blank\" rel=\"noopener\"\u003eTechnical Data Sheet\u003c\/a\u003e (PDF)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/res.cloudinary.com\/dzhpkjoqj\/Caleffi\/574050A_CALE-574050A_8016615577907_Inst.pdf\" target=\"_blank\" rel=\"noopener\"\u003eInstallation \u0026amp; Operation Manual\u003c\/a\u003e (PDF)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/res.cloudinary.com\/dzhpkjoqj\/Caleffi\/574050A_CALE-574050A_8016615577907_Sub.pdf\" target=\"_blank\" rel=\"noopener\"\u003eSubmittal Sheet\u003c\/a\u003e (PDF)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/res.cloudinary.com\/dzhpkjoqj\/Caleffi\/574050A_CALE-574050A_8016615577907_Sell.pdf\" target=\"_blank\" rel=\"noopener\"\u003eTechnical Bulletin\u003c\/a\u003e (PDF)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSee also: \u003ca href=\"\/collections\/backflow-preventers\"\u003ebackflow preventers\u003c\/a\u003e, \u003ca href=\"\/collections\/caleffi-north-america\"\u003eall Caleffi products\u003c\/a\u003e.\u003c\/p\u003e","brand":"Caleffi","offers":[{"title":"Default Title","offer_id":50517449343079,"sku":"CALE-574050A","price":440.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0651\/2253\/3479\/files\/574050A_CALE-574050A_8016615577907.jpg?v=1792424510","url":"https:\/\/www.thehousesupplier.com\/products\/caleffi-574050a-574-series-reduced-pressure-zone-rpz-backflow-preventer-3-4-npt-threaded-asse-1013-low-lead","provider":"The House Supplier","version":"1.0","type":"link"}
