This 1 inch lead free 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 or backpressure, in accordance with national plumbing codes and water authority requirements.

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.

Design and Construction

• Features a modular, compact design to facilitate easy in-line maintenance.
• Constructed with a Lead Free* cast copper silicon alloy body.
• Includes NPT end connections and quarter turn ball valve shutoffs with tee handles.
• Equipped with top mounted test cocks.
• Contains two in-line independent positive seating check modules with captured springs, and replaceable check discs and seats.
• Applicable iron components are coated with ArmorTek®, a patented three-part advanced epoxy system, to reduce microbial-induced corrosion (MIC) and protect exposed metal substrate.

Freeze Sensor Technology

• An integrated freeze sensor works with SentryPlus Alert® technology to signal facility personnel when temperature nears and reaches the freezing point.
• Freeze alerts feature is available with an add-on connection kit (sold separately) for Wi-Fi networks, building management systems (BMS), and irrigation management systems (IMS).
• The sensor is installed on the assembly exterior and does not alter assembly functions or certifications.
