Additional Details

This 3/4 inch reduced pressure zone assembly backflow preventer, model 009M2-PC-QT, is designed to prevent the flow of polluted water from entering into the potable water supply due to backsiphonage and/or backpressure in accordance with national plumbing codes and water authority requirements.

Its compact modular design facilitates easy maintenance with a single access cover for in-line repairs. This assembly 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.

Construction & Design

  • Bronze body construction ensures durability and longevity.
  • Internal polymer coating provides extended corrosion protection.
  • Features two in-line independent check valves with captured springs.
  • Replaceable check seats and a removable internal relief valve seat allow for economical repair and reduced installation clearances.
  • Single access cover and modular check construction for ease of maintenance and immediate accessibility.
  • Large body passages provide low pressure drop.
  • Compact, space-saving design requires no special tools for servicing.

Connections & Operation

  • Equipped with NPT inlet and outlet connections.
  • Includes quarter turn full port resilient seated ball valve shutoffs with lever handles.
  • Features top-mounted test cocks.

An add-on connection kit is required to activate the flood sensor. Without the connection kit, the sensor is a passive component that has no communication with any other device.

FAQs

What is the primary function of this backflow preventer?

This 3/4 inch reduced pressure zone assembly is designed to prevent polluted water from entering the potable water supply by protecting against backsiphonage and backpressure, in compliance with national plumbing codes.

What type of connections does this assembly have?

This backflow preventer is equipped with NPT (National Pipe Taper) inlet and outlet connections for secure installation into plumbing systems. This ensures compatibility with standard threaded pipes.

How does the flood sensor work and what does it require?

The integrated SentryPlus Alert® flood sensor detects excessive water discharges from the relief valve. To activate its alert capabilities, an add-on connection kit (available separately, e.g., BMS, cellular, or Sensor Control Monitor) is required to enable communication.

What material is the body made from, and what is its internal coating?

The body of this backflow preventer is constructed from durable bronze. It features an internal polymer coating which provides extended protection against corrosion, enhancing its lifespan and reliability.

Are the internal components, like seats, replaceable for maintenance?

Yes, this model features replaceable check seats and a removable internal relief valve seat. This modular design allows for economical repairs and easy maintenance, contributing to the longevity of the assembly.
