Description

This 3 inch lead free reduced pressure zone backflow preventer assembly protects potable water supplies from pollution caused by backsiphonage and backpressure. Ideal for health hazard cross-connections and service line containment, it features a durable cast iron body with ArmorTek® advanced epoxy coating for superior corrosion resistance. Equipped with non-rising stem resilient seated gate valves and two independent check valves, this assembly ensures reliable backflow prevention. An integrated SentryPlus Alert® flood sensor detects relief valve discharge, with optional connectivity for remote alerts. It is approved to ASSE Std. 1013, AWWA C511, and CSA B64.4, offering a compact and easily maintainable solution.

Help Me Connect

This 3 inch reduced pressure zone backflow preventer assembly features flanged end connections for secure installation into your piping system. It is equipped with non-rising stem (NRS) gate valves for isolation.

The integrated SentryPlus Alert® flood sensor requires an add-on connection kit (sold separately) to enable active monitoring and alerts. Connection kit options allow for integration with Building Management Systems (BMS), cellular communication, or the Nexa® platform via Wi-Fi when utilizing a Sensor Control Monitor.

Additional Details

This 3 inch lead free reduced pressure zone backflow preventer assembly is engineered to safeguard potable water supplies from pollution caused by backsiphonage and backpressure.

It is ideally suited for continuous pressure piping applications, cross-connections identified as health hazards, and containment at the service line entrance.

Construction & Materials

  • Features a cast iron body with a patented ArmorTek® 3-part advanced epoxy coating system, designed to resist both microbial induced corrosion (MIC) and exposed metal substrate corrosion on internal and external surfaces.
  • Includes non-rising stem resilient seated gate valves for reliable shutoff.
  • Equipped with two in-line independent check valves, captured springs, and replaceable check seats for ease of maintenance.
  • An internal relief valve is designed for reduced space requirements, and top-mounted test cocks facilitate compliance testing.

Flood Sensor Technology

  • Integrates a flood sensor with SentryPlus Alert® technology to detect continuous discharge from the relief valve.
  • When paired with an add-on sensor connection kit (sold separately), the sensor activates to relay alerts for potential flooding events.
  • Connection kit options include compatibility with BMS (Building Management System), cellular communication, and the Nexa® platform through Wi-Fi via a Sensor Control Monitor, enabling remote maintenance alerts.

Installation requires careful adherence to all instructions, codes, and local regulations. Watts is not responsible for alert failures due to connectivity issues, power outages, or improper installation.

FAQs

What is a Reduced Pressure Zone (RPZ) backflow preventer?

An RPZ assembly is designed to protect potable water supplies from contamination by preventing the backflow of polluted water due to backsiphonage or backpressure. It maintains a pressure differential across two check valves and includes an internal relief valve.

What is the body material of this LF009 backflow preventer?

This 3-inch LF009 model features a robust cast iron body, which is coated with Watts' patented ArmorTek® 3-part advanced epoxy system to resist microbial induced corrosion (MIC) and protect exposed metal surfaces.

Does this backflow preventer include a flood sensor?

Yes, this assembly includes a SentryPlus Alert® flood sensor to detect continuous water discharge from the relief valve. To activate alerts and connect to external monitoring systems, an add-on connection kit is required (sold separately).

What type of shutoff valves are included with this assembly?

This Watts LF009-NRS-FS assembly is equipped with non-rising stem (NRS) resilient seated gate valves, which provide reliable isolation for maintenance and testing.

What are the primary certifications for this product?

This backflow preventer is approved to USC, ASSE Std. 1013, AWWA C511, and CSA B64.4, ensuring it meets recognized industry standards for performance and safety.
