Watts 88004114 Preventer

The Watts 88004114 (Model LF009M2-QT-FS) is a 1-1/2" reduced pressure zone (RPZ) backflow preventer designed specifically for high-hazard cross-connections. Built with lead-free bronze, this assembly provides critical protection for potable water supplies against backsiphonage and backpressure. It is the designated direct replacement for the legacy 0062921 model, ensuring a seamless retrofit for existing installations. The 009M2 series features a compact, modular design that simplifies in-line maintenance; the single-access top cover allows technicians to service both check modules and the internal relief valve without removing the entire unit from the line.

Engineered for professional performance, this 1-1/2 inch backflow assembly includes quarter-turn, full-port resilient seated ball valve shutoffs and NPT inlet/outlet connections. To assist with proactive system management, the unit comes equipped with an integrated flood sensor and SentryPlus Alert technology, which can notify contractors of excessive relief valve discharge when paired with a connection kit. Its low pressure-drop characteristics and captured springs make it a reliable choice for commercial and industrial potable water protection applications where space and safety are primary concerns.

• Direct Replacement: Fits the footprint of the older Watts 0062921 for faster swaps.
• Streamlined Maintenance: Single top-entry cover provides immediate access to all internals; check seats are fully replaceable.
• Enhanced Safety: Captured springs prevent accidental energy release during disassembly in the field.
• Durable Construction: Features a lead-free copper silicon alloy body that meets all current plumbing codes.
• Flood Detection: Integrated sensor identifies relief valve discharge to prevent costly facility damage.

• Is this unit compatible with my existing 1.5" piping? Yes, the 88004114 utilizes standard 1-1/2" NPT female threaded connections and handles up to 175 PSI.
• Does the flood sensor work out of the box? The sensor is a passive component; you must use a SentryPlus Alert connection kit to enable remote monitoring or BMS integration.
• Can the check valves be serviced individually? Absolutely. The modular design enables the independent removal of both check valves and the relief valve stem.
