This 1 inch Lead Free Double Check Valve Backflow Preventer Assembly is designed to prevent the backflow of polluted water into the potable water supply due to backsiphonage or backpressure.

It is ideal for protection in continuous pressure piping applications and at cross-connections identified as non-health hazards, ensuring compliance with national plumbing codes and water authority requirements.

Important Safety Information

• A freeze sensor is installed on the assembly exterior but requires an add-on connection kit (sold separately) to activate a monitoring system for freeze alerts. The sensor itself cannot prevent a freeze event; user action is required to prevent damage. Watts is not responsible for data transmission failures due to power outages, connectivity issues, or improper installation.
