Resideo AM100-US-1LF Valve

The Resideo AM100-US-1LF is a professional-grade lead-free thermostatic mixing valve designed for precise domestic hot water temperature control. Built with a 1/2-inch union sweat connection, this valve features a high-grade Teflon-coated internal shuttle to resist mineral buildup and ensure long-term reliability in hard water conditions. It operates with a temperature adjustment range of 70°F to 145°F, making it suitable for both scald protection and point-of-source tempering applications in residential and light commercial plumbing systems. The dual-purpose design allows for increased usable hot water capacity while maintaining constant outlet temperatures even during fluctuations in supply pressure. Compliance with ASSE 1017 standards and lead-free regulations ensures this mixing valve meets strict municipal codes. For contractors, the union hardware simplifies installation and maintenance, providing a robust solution for hydronic heating systems and potable water distribution.

• Constant Temperature Output: Proportional valve design maintains stable outlet temperatures despite varying inlet conditions.
• Lead-Free Construction: Meets all federal and state requirements for potable water safety.
• Scale Resistance: Teflon-coated components prevent calcium and lime deposits from compromising the valve's mechanical movement.
• Extended Hot Water Supply: Allows water heaters to be set at higher temperatures to kill bacteria while safely mixing down for user safety.

Common Installation Questions

Does this valve require a check valve on the cold water inlet?
Yes, for optimal performance and to prevent thermal siphoning or cross-flow between hot and cold lines, ensure check valves are installed as per local plumbing codes.

Can the AM100-US-1LF be used in radiant floor heating applications?
This model is frequently utilized in radiant heating loops to temper manifold supply temperatures, provided the flow rate requirements fall within its specified CV rating.

What is the minimum flow rate required for accurate tempering?
This valve is engineered to maintain accuracy even at low flow rates, typically down to 0.5 GPM, which is essential for modern low-flow fixtures.
