The health and safety of you and those around you is so incredibly important, especially when it comes to hot water in your home and workplace. Ensuring that the thermostatic mixing valves are working like they should can mean stopping someone from badly injuring themselves, so give the Ryan Old Plumbing team a call today for further help and information.


What is a thermostatic mixing valve?

A thermostatic mixing valve, which is also known as a TMV, is a tool that combines hot and cold water together to maintain a specific water temperature when sending water through a faucet.

What does a TMV do?

A TMV mixes both hot and cold water together so it is a particular temperature, within 1℃ +/-, so it can be sent to different water outlets. The temperature is generally prearranged by a tradesperson or a qualified plumber , and the TMV element that responds to thermal activity alters the levels of hot and/or cold water to ensure the correct temperature of liquid.

According to National Plumbing and Drainage Standard AS/NZS 3500.4: 2003, some water installations are not permitted to deliver water at a temperature higher than 50℃/45℃, which is why a TMV is installed - to assist with temperature regulation.

Who should have a TMV installed?

The following locations should all have a TMV installed:

  • Aged care facilities and nursing homes.
  • Hospitals.
  • Childcare facilities and after school care.
  • Respite centres.
  • Shopping centre bathroom facilities.
  • Hotels.

Generally, any environment that contains high risk individuals, including children, the sick and the elderly, require a TMV as they require lower water delivery temperatures - usually 45℃ or 113℉ at its hottest.

Can I install a thermostatic mixing valve myself?

No, installing a TMV is not a DIY project and can be dangerous if done incorrectly. Only an appropriately qualified plumber with a TMV licence is allowed to install the device - and the Ryan Old Plumbing team are exactly that. Call today!
