1/2" TMV COM ADPT w/o CHECK

This brass adapter connects a thermostatic mixing valve in residential or light-commercial plumbing systems. It is supplied new from Legend Valve and carries a transparent finish for visual inspection of the joint. The 1/2" nominal size fits standard copper or PEX supply lines without additional reducers.

Installers needing a check-valve function should

This fitting omits an integral check valve, so it cannot prevent backflow on its own. Projects that require built-in backflow protection or a different thread configuration will need a separate component. The part is intended for use where a check valve is already present or not required by local code.

Lead-content warning applies under California

The product contains a chemical listed by the State of California as known to cause cancer and birth defects or other reproductive harm. Installers should follow standard safety practices such as flushing lines before use and washing hands after handling. No performance degradation under sustained pressure or temperature cycling is documented in the supplied data.

Questions about this item

What pipe size must my existing plumbing be for this 1/2" adapter to connect?

Your supply lines must be 1/2" nominal diameter so the compression ends seat properly.

Will this thermostatic mixing valve work with an older non-pressure-balance shower valve?

Yes — it blends hot and cold water downstream of the existing valve, so the older valve still controls on/off while this unit limits temperature.

How can I verify the valve is delivering a safe mixed temperature after installation?

Run the outlet and measure the water with a thermometer; it should stay within the valve's preset limit.
