Additional Details

This 1 1/2 inch Lead Free double check valve backflow preventer assembly prevents the backflow of polluted water into the potable water supply from backsiphonage or backpressure. It is suitable for continuous pressure piping applications and non-health hazard cross-connections, meeting national plumbing codes and water authority requirements.

WARNING: The freeze sensor provides alerts about a possible freeze event but cannot prevent it. User action is required to prevent freeze conditions from causing product and/or property damage.

Features

  • Includes a freeze sensor for use with SentryPlus Alert® technology to signal facility personnel about low and freezing temperatures.
  • An add-on connection kit (sold separately) is required to activate the freeze sensor; without it, the sensor is a passive component with no communication.
  • Lead Free* cast copper silicon alloy body construction.
  • Modular, compact design for easy maintenance and assembly by retaining the spring load.
  • Replaceable seats and seat discs accessible through a single, top-entry cover for simplified servicing.
  • ArmorTek coating technology applied to internal and external surfaces to resist microbial-induced corrosion (MIC).
  • Equipped with quarter turn ball valve shutoffs and top-mounted Lead Free* test cocks.
  • Designed with two in-line independent positive seating check modules and captured springs.

FAQs

What is the primary function of the Watts LF007M2-QT-FZ backflow preventer?

This assembly is designed to prevent the backflow of polluted water from entering the potable water supply, protecting against both backsiphonage and backpressure in accordance with national plumbing codes.

What does the 'Lead Free' construction imply for this product?

The 'Lead Free' designation means the product's wetted surface contains less than 0.25% lead by weight. This complies with Lead Free installation requirements and ensures the safety of the potable water supply.

How does the integrated freeze sensor operate?

The integrated freeze sensor uses SentryPlus Alert® technology to provide alerts about possible freeze events. An add-on connection kit, sold separately, is required to activate the sensor's monitoring system for communication with Wi-Fi, BMS, or IMS.

Is this backflow preventer easy to service or repair?

Yes, its modular, compact design features a single top-entry cover, making it easy to access and replace internal components like seats and discs for in-line repairs without requiring special tools.

What are the connection types and shutoff features of this assembly?

This assembly is equipped with NPT end connections and union connections for versatile installation. It also includes quarter turn ball valve shutoffs for effective isolation.
