Thermostatic Mixing Valves

Help protect against both scalding and bacteria in your water supply with these quality thermostatic mixing valves. These valves allow you to set your water heater to the recommended 140°F to reduce bacteria, while sending cooler 120°F water to your faucets, showers, and tub. Available for a wide range of applications - water heater, point-of-use, metering showers, multiple fixtures, underfloor hydronic heating, etc. - we've got the valve you need. As an added bonus, that higher tank temperature means hot water demands can be satisfied longer so you don't have to worry about being last in the shower anymore.

Frequently Asked Questions

Q. "What are check valves?"
A. Check valves prevent the back flow and cross flow of water. With a check valve water can only flow one direction. Check valves are recommended to prevent by-pass when a Thermixer is installed with a downstream shut-off device.

Q. "What are screwdriver stops?"
A. With stops, it means the valve has shut-offs for the water line so you don't have to shut off water to the entire house to work/repair parts on the shower/tub system.
