Watts 0204152 Mix Valve
For high-performance temperature control in commercial and residential potable water systems, the Watts 0204152 Under Sink Guardian is the industry standard. This LFUSG-B-M3 thermostatic mixing valve features a lead-free brass body and 3/8-inch male compression fittings, designed for direct installation between stop valves and the faucet. As a direct replacement for the 0204143 (LFUSG-B-M2), this valve utilizes a double throttling design to regulate both hot and cold inlets simultaneously, ensuring accurate delivery of tempered water between 80°F and 120°F. The internal copper thermostat reacts rapidly to pressure fluctuations, maintaining a stable discharge temperature to minimize scalding risks. With a low flow rate capability of 0.25 to 2.25 GPM and ASSE 1070 certification, this lead-free mixing valve is essential for meeting rigorous plumbing codes in point-of-use applications. Integrated 40-mesh stainless steel strainers and dual check valves prevent cross-flow and debris accumulation, protecting the cartridge and downstream fixtures.
Key Benefits- Precise Temperature Regulation: Maintains a constant discharge temperature even during radical pressure or inlet temperature shifts.
- Scald Protection: Engineered for point-of-use safety, limiting maximum hot water delivery in restrooms and kitchens.
- Cross-Flow Prevention: Features dual integrated check valves to ensure hot and cold water do not migrate between supply lines.
- Durable Construction: Built with a lead-free brass body and corrosion-resistant stainless steel internal components for long-term reliability.
- Code Compliance: Fully ASSE 1070 and cUPC listed, meeting strict safety standards for single-fixture tempering.
Is the Watts 0204152 compatible with the older 0204143 model?
Yes, the 0204152 (LFUSG-B-M3) is the direct, updated replacement for the 0204143 (LFUSG-B-M2). It maintains the same 3/8-inch compression footprint for simple drop-in retrofitting.
What is the maximum pressure rating for this mixing valve?
The Watts Under Sink Guardian is rated for a maximum working pressure of 150 psi (10.3 bar), making it suitable for high-pressure commercial water systems.
How do you adjust the temperature setting on this valve?
Adjustments are made via the tamper-resistant locking cap. Professionals should use a thermometer at the faucet to calibrate the output, typically targeting a discharge temperature of 105°F for optimal safety.
