This 2 inch lead-free reduced pressure zone backflow preventer assembly is engineered to prevent the backflow of polluted water into potable water supplies. It features an integrated flood sensor with SentryPlus Alert® technology, detecting relief valve discharges and relaying alerts for potential flooding when used with a connection kit. Built with lead-free bronze, it includes NPT end connections, quarter turn ball valves, a bronze strainer, and an air gap fitting. Its compact design and accessible test cocks make it ideal for various continuous pressure piping applications.
This 2 inch lead free reduced pressure zone backflow preventer assembly is designed to prevent the flow of polluted water from entering the potable water supply due to backsiphonage and/or backpressure.
It includes a flood sensor with SentryPlus Alert® technology to detect 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.

FAQs
What is the primary function of this backflow preventer?
This backflow preventer assembly is designed to prevent polluted water from flowing back into the potable water supply due to backsiphonage or backpressure, protecting the drinking water quality.
What is SentryPlus Alert® technology?
SentryPlus Alert® technology refers to the flood sensor integrated into the assembly. It detects continuous water discharge from the relief valve and can relay alerts for potential flooding events when paired with a compatible connection kit.
What materials is this backflow preventer made from?
The body of this backflow preventer is constructed from lead-free bronze, ensuring safety for potable water applications. It also includes other durable components like bronze for the strainer.
How does the flood sensor connect to monitoring systems?
The flood sensor, when paired with an add-on connection kit, can integrate with the Sensor Control Monitor to deliver maintenance alerts to a Building Automation System (BAS) via RS-485 Modbus or to the Nexa® platform through Wi-Fi connectivity.
Does this backflow preventer come with shutoff valves and a strainer?
Yes, this assembly includes quarter turn ball valve shutoffs with tee handles for easy operation and a bronze strainer to protect internal components from debris.
