{"product_id":"watts-f122774","title":"Watts LF909-QT-S-FS 3\/4 Lead-Free RPZ Backflow Preventer, Copper","description":"\u003cp\u003eThe Watts LF909-QT-S-FS 3\/4 is a 3\/4\" lead-free reduced pressure zone (RPZ) backflow preventer, approved for high health hazard protection. It features a copper body. 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 3\/4 inch lead free reduced pressure zone backflow preventer assembly with its exclusive design incorporating the patented air-inch and water-out principle for protection during an emergency condition prevents the flow of polluted water from entering into the potable water supply due to backsiphonage and or backpressure. Ideal for protection inch continuous pressure piping applications and at cross-connections identified as health hazards and from other contaminants. This assembly consists of a lead free body, quarter turn ball valve shutoffs with tee handles, a strainer, check modules, replaceable seats, top mounted test cocks, and a pressure differential relief valve. It can be installed horizontal or vertical without the need of any special tools. 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 continuous discharge from the relief valve\u003c\/li\u003e\n\u003cli\u003eAdd-on sensor connection kit to extend flood monitoring on compatible assemblies\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\u003eLead free construction\u003c\/li\u003e\n\u003cli\u003eUnique patented air-in and water-out design provides high capacity relief valve discharge performance during emergency conditions\u003c\/li\u003e\n\u003cli\u003eCompact for easy installation\u003c\/li\u003e\n\u003cli\u003eQuarter-turn ball valves with tee handles\u003c\/li\u003e\n\u003cli\u003eHorizontal or vertical (up or down) installation\u003c\/li\u003e\n\u003cli\u003eIncludes: Test Cocks\u003c\/li\u003e\n\u003cli\u003eIncludes: Strainer\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 RPZ 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. 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 3\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size:\u003c\/strong\u003e 3\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size:\u003c\/strong\u003e 3\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e Copper\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 Domestic Water\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 LF909-QT-S-FS 3\/4\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-909, ASSE-1013, CSA-B64, USC, IAPMO\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 RPZ\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 909;ASSE 1013\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSC FCCCHR Approved:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eField Testable:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Test Cocks:\u003c\/strong\u003e 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShutoff Valves:\u003c\/strong\u003e Quarter-Turn Ball\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproved Orientation:\u003c\/strong\u003e Horizontal \u0026amp; Vertical\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 Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Gap Fitting Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Watts","offers":[{"title":"Default Title","offer_id":54935311647019,"sku":"F122774","price":2579.13,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0277\/3168\/9577\/files\/adeaf0652ddc42a3b0612d180c9f60679cd5a7ad.jpg?v=1785983671","url":"https:\/\/citysupplygroup.com\/products\/watts-f122774","provider":"City Supply","version":"1.0","type":"link"}
