Product Identity

The Taco 5123-C2 is a thermostatic mixing valve built from forged brass for residential and light-commercial plumbing. It blends hot and cold water to a stable output between 85 and 120 degrees Fahrenheit at flow rates from 1 to 14 gpm.

Interface Constraints

The valve accepts 3/4-inch union sweat connections on both inlet and outlet, limiting direct installation to copper piping of that size. Maximum working pressure is 200 psi, and supply temperatures must stay within 39 to 80 degrees Fahrenheit cold and 120 to 180 degrees Fahrenheit hot.

Upgrade Context

It replaces older non-thermostatic mixing valves or basic tempering devices that lack integral check valves and third-party certification. The jump is justified when ASSE 1017, ASSE 1070, CSA 125.3 and NSF 61 compliance are required by code or specification.

Questions about this item

Should I pick a valve rated for 1 to 14 gpm or one with a narrower range?

The 1 to 14 gpm span covers most residential and light-commercial fixtures, so you can size the valve to the actual demand without needing multiple models.

What does the 14 gpm flow rating mean when the valve is installed?

It is the maximum mixed-water volume the valve can deliver while maintaining the set temperature across the 85 to 120 °F range.

What standard governs the union sweat connections and what pressure do they handle?

The valve meets ASSE 1017 and ASSE 1070, and the forged brass body is rated for 200 psi maximum working pressure.
