The assembly features quarter turn ball valves for fast shutoff and includes an integrated flood sensor with SentryPlus Alert technology. The sensor monitors the relief valve outlet and activates alerts when water discharge is detected, giving service technicians early warning of potential flooding events. This assembly is installed by licensed plumbers on continuous pressure piping systems where cross-connections pose a health hazard.\u003c\/p\u003e\n\u003cp\u003eThe LF919QT-FS-100 is suited for commercial and residential applications at the service line entrance and at cross-connections classified as health hazards under local plumbing codes. When paired with an optional add-on connection kit, the flood sensor can relay alerts through multiple communication pathways. Connection kit options include BMS integration, cellular communication, and the Sensor Control Monitor, which supports RS-485 Modbus communication with building automation systems (BAS) or Wi-Fi connectivity through the Nexa platform. This range of alert options makes the assembly a practical fit for facilities that require remote monitoring of backflow preventer status.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead free construction meets applicable safe drinking water requirements for potable water systems\u003c\/li\u003e\n  \u003cli\u003eReduced pressure zone design protects against both backsiphonage and backpressure at health hazard cross-connections\u003c\/li\u003e\n  \u003cli\u003eIntegrated SentryPlus Alert flood sensor detects relief valve discharge and triggers alerts\u003c\/li\u003e\n  \u003cli\u003eQuarter turn ball valves allow fast, positive shutoff without special tools\u003c\/li\u003e\n  \u003cli\u003eCompatible with optional connection kits supporting BMS, cellular, RS-485 Modbus, and Wi-Fi Nexa platform communication\u003c\/li\u003e\n  \u003cli\u003eSuitable for continuous pressure piping applications at the service line entrance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in continuous pressure potable water piping systems where cross-connections are identified as health hazards.

Shut off the water supply and depressurize the line before servicing or installing the assembly. The assembly must be installed in the orientation specified by the manufacturer and requires annual testing by a certified backflow preventer tester in most jurisdictions. Do not install in a location subject to submersion unless the assembly is rated for that condition.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAssembly Type\u003c\/strong\u003e: Reduced Pressure Zone (RPZ) Backflow Preventer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShutoff Valves\u003c\/strong\u003e: Quarter Turn Ball Valves\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlood Sensor\u003c\/strong\u003e: SentryPlus Alert Technology\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCommunication Options\u003c\/strong\u003e: BMS, Cellular, RS-485 Modbus, Wi-Fi (Nexa platform) via optional add-on connection kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WATTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LF919QT-FS-100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51525386404146,"sku":"LF919QT-FS-100","price":492.56,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/watts-lf919qt-fs-100-rpz-backflow-preventer-1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
