It features a ductile iron body. Rated to 175 psi and up to 140°F. This model is certified lead-free for potable-water installations.\u003c\/p\u003e\u003cp\u003eThe 375DA Reduced Pressure Principle Detector Backflow Assembly protects against backsiphonage and backpressure of contaminated water in high hazard, fire protection applications. The 375DA features a metered bypass to effectively detect leaks and any unauthorized water use. Materials include an epoxy-coated ductile iron body, and stainless steel internals, fasteners, springs, and sensing line. The Wilkins Compound Check provides low headloss and superior performance and valves short lay-lenght makes the 375DA ideal for any backflow replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRelief valve and checks are easily accessible for in-line maintenance\u003c\/li\u003e\n\u003cli\u003eLeak and unauthorized water use detection decreases costs over time\u003c\/li\u003e\n\u003cli\u003eProtection from contaminated water in high hazard fire protection applications\u003c\/li\u003e\n\u003cli\u003eEpoxy-coated ductile iron body and stainless steel internals resist corrosion\u003c\/li\u003e\n\u003cli\u003eLowest lifecycle costs\u003c\/li\u003e\n\u003cli\u003eUL® Classified\u003c\/li\u003e\n\u003cli\u003eAWWA Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat hazard level is this RPDA approved for?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eIt is rated for high health hazard (toxic) cross-connections, so it may be used on either high or low hazard service.

An RPZ relief valve is designed to discharge, and it can dump a large volume of water, so it must never be installed in a pit or below grade and the discharge must be piped to an adequate drain through an air gap. The air gap fitting is not included with this model and is ordered separately.\u003c\/dd\u003e\n\u003c\/dl\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Backflow Preventer - Reduced Pressure Principle Detector Assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 6\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Flanged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e Ductile Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Pressure (psi):\u003c\/strong\u003e 175\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Fire Protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackflow Protection:\u003c\/strong\u003e Both\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 6-375DA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature:\u003c\/strong\u003e up to 140°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e ASSE-1047, AWWA-C550, AWWA-C606, CSA-B64.4, C-UL, UL, FM, USC, NSF-61, NSF-372\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead-Free:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssembly Type:\u003c\/strong\u003e RPDA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHazard Protection Level:\u003c\/strong\u003e High Health Hazard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eASSE Standard:\u003c\/strong\u003e ASSE 1047\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSC FCCCHR Approved:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFire Protection Listing:\u003c\/strong\u003e UL Classified;C-UL Classified;FM Approved\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eField Testable:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShutoff Valves:\u003c\/strong\u003e NRS Gate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBypass Meter:\u003c\/strong\u003e GPM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Zurn","offers":[{"title":"Default Title","offer_id":55656179466539,"sku":"6-375DA","price":14921.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0277\/3168\/9577\/files\/375DA_AF_02180ea0-d30f-47ba-9a11-f86cf0a6bac2.jpg?v=1790041894","url":"https:\/\/citysupplygroup.com\/products\/zurn-6-375da","provider":"City Supply","version":"1.0","type":"link"}
