This 1 inch double check valve backflow preventer assembly is designed to prevent the backflow 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. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as non-health hazards.

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

Construction & Design

• Features investment cast 316 stainless steel for superior corrosion resistance.
• All wetted valve components (test cocks, ball valve shutoffs, pipe nipples, body and cover, and check modules) are made from Lead Free stainless steel or plastic construction.
• Bolted-on, top-entry, single access cover allows for ease of maintenance.
• Modular check construction with nonreversible checks and captured springs for simplified servicing.
• Includes top-mounted, vandal-resistant EZ-TC-SS test cocks requiring no tools or fittings for easy access during testing.
• Stainless steel test cocks include dust covers to protect threads from dirt, dust, and insects.
• Replaceable check valve seats require no special tools.
• True line sized check modules reduce fouling from dirt and debris.
• Incorporates a protective stainless steel Wye strainer with a 20 mesh screen.

Freeze Sensor Technology

• Equipped with a freeze sensor for use with SentryPlus Alert® technology to monitor temperature and alert facility personnel when freeze conditions can cause damage.
• Sensor provides flexibility in locating a measuring tool at or near any water-carrying outdoor installation vulnerable to freezing.
• An add-on connection kit (sold separately) is required to activate the freeze sensor's monitoring system and trigger alerts for low and freezing temperatures.
• Built-in Wi-Fi function communicates freeze alerts directly to the user (with connection kit), eliminating the need for a third-party controller.
• Switched output relay can augment BMS or irrigation management systems with reinforced control of sprinkler systems.
