  • This assembly features NPT end connections for easy installation into existing piping systems.

Flood Sensor Compatibility

The integrated SentryPlus Alert® flood sensor requires an add-on connection kit (sold separately) to activate its alert capabilities. Once activated, the sensor can relay alerts through various systems including:

  • Building Management Systems (BMS)
  • Cellular communication
  • The Sensor Control Monitor for integration with Building Automation Systems (BAS) via RS-485 Modbus or the Nexa® platform through Wi-Fi connectivity.

FAQs

What is the primary function of this backflow preventer?

This backflow preventer assembly is designed to protect potable water supplies by preventing polluted water from flowing back into the system due to backsiphonage or backpressure.

What material is the body made from?

The body of this assembly is constructed from cast iron, which is then coated with ArmorTek®, a patented 3-part advanced epoxy system, to resist microbial induced corrosion (MIC) and protect the metal substrate.

Does this backflow preventer include a flood sensor?

Yes, it includes a SentryPlus Alert® flood sensor that detects excessive water discharges from the relief valve. An add-on connection kit (sold separately) is required to activate the alert features.

What type of connections does this assembly have?

This 3 inch backflow preventer assembly is furnished with NPT (National Pipe Taper) end connections.

What is the maximum operating pressure for this unit?

This assembly is suitable for supply pressures up to 175 PSI (12.1 bar).
