A thermostatic mixing valve (TMV) is a valve that controls water temperature for bathing, showering and hand-washing. They maintain water temperature by controlling the flow of hot and cold water, and unlike mechanical mixing valves, TMVs adjust for changes in flow rate/water pressure, to provide a consistent and predictable water temperature.

TMVs are an important safety feature. By limiting water temperature and how fast the temperature can change, TMVs prevent scalding. Something which results in 20 deaths a year, and almost 600 severe injuries, primarily to children and adults over 65. It also protects those who are physically or mentally less able to react to or judge water temperature correctly.

We install and repair TMVs, as well as servicing them, something which should be done annually.
