Resideo Braukmann AM-1 Anti-Scald Mixing Valve

Resideo Braukmann AM-1 anti-scald mixing valves protect people and equipment by blending hot and cold water to a set, stable temperature before it reaches a fixture. The valve maintains that mixed temperature even as supply pressure or incoming water temperature shifts, and if the cold water supply is interrupted, flow reduction happens within seconds to prevent a scald hazard. AM-1 valves ship in lead-free brass construction with a minimum flow rate of 0.5 gpm, and connection options include sweat, NPT, PEX, ProPress, CPVC, and push-connect fittings across half inch, three quarter inch, and one inch sizes. That range of connection types lets a plumber match the valve to whatever piping is already run at the point of installation instead of adding transition fittings. For water heater setups where storage temperature is raised to limit bacteria growth, a mixing valve like the AM-1 brings the temperature back down to a safe level at the outlet.

Subcategories

• Standard Mixing Valve Bodies: Standard AM-1 valve bodies handle general potable water mixing for showers, tubs, and other fixtures where a stable outlet temperature matters. They come in lead-free brass and support the same range of connection types as the rest of the line.
• Radiant Mixing Valve Bodies: Radiant-specific AM-1 bodies are built for hydronic heating loops rather than potable fixtures, blending supply water to a temperature suited to radiant floor or snowmelt systems. Contractors select these when the mixing point feeds a heating loop instead of a tap.
• Replacement Cartridges and Parts: Replacement cartridges and adapter parts let contractors service an existing AM-1 valve without replacing the entire body. Keeping common cartridge sizes on hand cuts down on truck rolls back to the supply house mid-repair.

Buying Guide

Choosing a Resideo Braukmann AM-1 Anti-Scald Mixing Valve starts with confirming whether the application is a potable water fixture or a hydronic heating loop, since Resideo offers separate standard and radiant valve bodies for those two uses. Installing the wrong body type on a radiant loop can leave the system without the temperature range the heating design calls for.

Connection type is the next decision point. The AM-1 line supports sweat, NPT, PEX, ProPress, CPVC, and push-connect fittings across half inch, three quarter inch, and one inch sizes, so contractors should match the valve to whatever piping is already run rather than defaulting to a size or connection type out of habit. Confirming flow rate needs matters too, since the valve has a minimum flow rate of 0.5 gpm and undersizing a valve on a high-demand fixture can leave water pressure feeling weak at the tap.

For water heater installations where storage temperature is set higher than the desired delivery temperature, often to control bacteria growth in the tank, an AM-1 valve at the outlet brings the mixed water back down to a safe level before it reaches a fixture. The valve's automatic flow reduction if cold water supply is interrupted is also worth confirming during installation, since it is the feature that prevents a scald injury in that failure scenario.

Frequently Asked Questions

What happens to a Resideo Braukmann AM-1 valve if the cold water supply fails?

The AM-1 valve reduces flow within seconds if the cold water supply is interrupted, preventing scalding hot water from reaching the fixture. That automatic response is a core part of the valve's anti-scald function.

What connection types does the AM-1 valve support?

The AM-1 line supports sweat, NPT, PEX, ProPress, CPVC, and push-connect connections across half inch, three quarter inch, and one inch sizes. Contractors can match the valve to existing piping without adding transition fittings.

Is there a difference between standard and radiant AM-1 valve bodies?

Yes, Resideo offers a standard body for potable water fixtures and a separate radiant body built for hydronic heating loops. The two are not interchangeable, since they are tuned for different applications.

What is the minimum flow rate for the AM-1 valve?

The AM-1 valve has a minimum flow rate of 0.5 gpm. Contractors should confirm that fixture demand will meet or exceed that minimum for the valve to regulate temperature properly.

Why would a water heater need a mixing valve like the AM-1?

Water heaters are sometimes set to a higher storage temperature to limit bacteria growth in the tank. A mixing valve at the outlet blends that hotter water down to a safe delivery temperature before it reaches a fixture.
