Comments about 3/4" NPT Mixing Valve:

Mixing valve controls hot water temperature at the faucet. Prevents scalding. You forget how much you depend on it until you go to someone else's house and turn on their hot water, and are reminded just how hot it can get. Especially if you have kids or older people in the house, who can accidentally bump the shower control knob and change the temperature setting, this device is worth it.

One tip; because it mixes hot and cold water to get the right temperature, minerals dissolved in the very hot water can crystalize when the water is cooled down, and deposit minerals in the valve (if you've got hard water). My original unit gradually started delivering cooler and cooler water, as the mineral deposits built up inside. I replaced the unit (after 8 years), but when I took out the old one I realized that I probably could have cleaned out the mineral deposits and had it working right again. But they're not that expensive, so I just installed the new one.

    We us this valve to mix the water to our showers at a mental hosp. The hot water line is recir. so there is no wait for hot water. the hot water is soft. the water coming back on the recir line is hard. Is it possable the cold water at the mixing valve iscoing into the hot water recir line?

      It sounds like the mixing valve may not be piped correctly. Unfortunately, since we do not have access to the specific schematics of your system, we recommend contacting a professional to assess the problem.
