{"product_id":"watts-88009369","title":"Watts 909RPDA-LF-GPM-FS 6 Lead-Free RPZ Backflow Preventer, Cast Iron","description":"\u003cp\u003eThe Watts 909RPDA-LF-GPM-FS 6 is a 6\" lead-free reduced pressure detector assembly (RPDA), approved for high health hazard protection. It features a cast iron body and a rubber seat. Rated to 175 psi and 33°F to 140°F. This model is certified lead-free for potable-water installations.\u003c\/p\u003e\u003cp\u003eThis 6 inch reduced pressure detector backflow preventer assembly prevents the reverse flow of fire protection system substances from being pumped or siphoned into the potable water supply due to backsiphonage and or backpressure. This assembly without the shutoff valves consists of an epoxy coated cast iron body, captured spring check valves, replaceable stainless steel seats, top mounted test cocks, a pressure differential relief valve, and comes furnished with a GPM meter to detect underground leaks and unauthorized water use. The coating on this backflow assembly uses ArmorTek®, a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion. This backflow assembly contains a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve. When paired with an add on connection kit, the sensor is activated to relay alerts for potential flooding events. Connection kit options include BMS, cellular communication, and the Sensor Control Monitor which enables integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFeatures a flood sensor with SentryPlus Alert technology to detect excessive water discharges from the relief valve\u003c\/li\u003e\n\u003cli\u003eIntegrates with the Sensor Control Monitor to deliver maintenance alerts to BAS via RS-485 Modbus or the Nexa platform by Wi-Fi connectivity\u003c\/li\u003e\n\u003cli\u003eUtilizes advanced ArmorTek coating technology to resist corrosion of internals\u003c\/li\u003e\n\u003cli\u003eCast iron body construction with patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion\u003c\/li\u003e\n\u003cli\u003eReplaceable stainless steel seats\u003c\/li\u003e\n\u003cli\u003eFurnished with a gallon per minute meter\u003c\/li\u003e\n\u003cli\u003eMaximum flow at low pressure drop\u003c\/li\u003e\n\u003cli\u003eDetects underground leaks and unauthorized water use\u003c\/li\u003e\n\u003cli\u003eCompact for economy combined with performance\u003c\/li\u003e\n\u003cli\u003eIncludes: Test Cocks\u003c\/li\u003e\n\u003cli\u003eIncludes: Flood Sensor\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.

It is certified lead-free to NSF\/ANSI 372, which is what state plumbing codes require for any device in a drinking-water line.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes this assembly have to be tested every year?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. This is a field-testable assembly. Most water authorities require it to be tested and certified by a licensed backflow tester at installation and annually thereafter. It carries USC FCCCHR approval, which many jurisdictions accept as their sole approval list.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes this ship with inlet and outlet shutoff valves?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eNo. This is the \"less valves\" (LF) configuration — the assembly ships without inlet and outlet shutoffs. Most jurisdictions require approved shutoffs on both sides, so order them separately or choose a QT, NRS, OSY or BFG variant of this model.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eIs this suitable for a fire sprinkler line?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. Detector assemblies are built for fire sprinkler service: the metered bypass registers the low flows that reveal a leak or an unauthorized tap on the fire line. This model is UL Classified and FM Approved. The bypass meter reads in GPM.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes the relief valve need a drain?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. 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. This model includes the SentryPlus Alert flood sensor, which signals a relief-valve discharge before it becomes a flood.\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 RPZ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 6\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size:\u003c\/strong\u003e 6\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size:\u003c\/strong\u003e 6\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat \/ Seal Material:\u003c\/strong\u003e Rubber\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\u003eOperation:\u003c\/strong\u003e Continuous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United States\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1 Year Limited\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 909RPDA-LF-GPM-FS 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature:\u003c\/strong\u003e 33°F to 140°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e ASSE-1047, CSA-B64, UL, FM, USC\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;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 None\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlood Sensor (SentryPlus Alert):\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrainer Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Gap Fitting Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBypass Meter:\u003c\/strong\u003e GPM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Watts","offers":[{"title":"Default Title","offer_id":54935298638123,"sku":"88009369","price":22282.34,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0277\/3168\/9577\/files\/18bc252fc1e4c1c655a59af0ccf85b5aa6412894.jpg?v=1785983413","url":"https:\/\/citysupplygroup.com\/products\/watts-88009369","provider":"City Supply","version":"1.0","type":"link"}
