Watts 88004089 Pressure Zone

The Watts 88004089 (Series LF009M3-QT-S-FS) is a high-performance 3/4 inch reduced pressure zone assembly engineered for critical backflow prevention in high-hazard applications. This lead-free bronze unit is built with a copper silicon alloy body and includes an integrated SentryPlus Alert flood sensor to monitor discharge from the relief valve. Its compact, modular design allows for streamlined in-line maintenance and repair, while the included strainer protects the assembly from debris-related fouling. Designed for potable water safety, it prevents both backsiphonage and backpressure in continuous pressure piping systems.

As a veteran's choice for mechanical contractors, this assembly features quarter-turn ball valve shutoffs with tee handles and screwdriver-slotted test cocks for efficient testing. The internal relief valve and captured springs enhance safety during service, and the use of replaceable check seats ensures the unit can be maintained in the field without complete replacement. This model is ideal for service line entrances and cross-connections where health hazard protection is a priority.

• Enhanced Flood Protection: Features an integrated flood sensor with SentryPlus Alert technology to detect excessive relief valve discharge (requires add-on connection kit).
• Lead-Free Reliability: Constructed from lead-free copper silicon alloy for maximum corrosion resistance and compliance with national plumbing codes.
• Streamlined Servicing: A single access cover provides immediate entry to internal components, ensuring serviceable backflow performance with no special tools required.
• Debris Protection: Factory-furnished with a strainer to prevent sediment from damaging internal check valves and seats.
• High Pressure Capacity: Rated for a maximum working pressure of 175 PSI and temperatures up to 180°F.

• How do I activate the flood sensor? The integrated sensor requires an add-on sensor connection kit (sold separately) to communicate via BMS, Wi-Fi, or cellular networks.
• Can this be installed vertically? While the Watts 009 series is primarily designed for horizontal installation, always verify local code requirements for vertical orientation in your specific jurisdiction.
• Is this assembly suitable for health hazards? Yes, the reduced pressure zone design is the standard for high-hazard cross-connections where potential contaminants are present.
