This 6 inch lead free reduced pressure zone backflow preventer assembly prevents the reverse flow of polluted water from entering into the potable water supply due to backsiphonage and/or backpressure. It is designed for protection in continuous pressure piping applications and at cross-connections identified as health hazards.

The assembly features an epoxy coated cast iron body, domestic non-rising stem resilient seated gate valves, captured spring check valves, replaceable seats, top mounted test cocks, and a field reversible pressure differential relief valve. The coating utilizes ArmorTek®, a patented 3-part advanced epoxy system engineered to limit both microbial induced (MIC) and exposed metal substrate corrosion.

Flood Sensor Features

• Includes 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 to facility personnel.
• 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.

Use of the flood sensor does not replace the need to comply with all required instructions, codes, and regulations related to installation, operation, and maintenance, including the need to provide proper drainage in the event of a discharge. Watts is not responsible for the failure of alerts due to connectivity issues, power outages, or improper installation.

Additional Features

• Replaceable seats and stainless steel internal parts for easy maintenance.
• Captured spring check assemblies.
• Fused epoxy coated and lined checks.
• ArmorTek coating technology resists corrosion of internals.
• Industrial-strength sensing hose.
• Field reversible relief valve.
• Air-in/water-out relief valve design provides maximum capacity during emergency conditions.
