Facilities have a duty of care to maintain a safe environment for all those using their property. This includes the delivery of hot water at a safe temperature, whilst reducing the risk of Legionella bacteria growth in water storage tanks. This can be achieved by installing and maintaining a thermostatic mixing valve (TMV).

The TMV blends hot water with cold to reduce the temperature of the water coming from the hot water system from the storage temp of 60℃+ to a much safer 50 or 45℃ outlet temperature. This measure helps prevent scalding and burns.

Thermostatic mixing valves are often installed in the following centres to ensure delivery of a constantly safe hot water supply:

  • Nursing homes
  • Child care centres
  • Shopping and retail centres
  • Respite facilities
  • Aged care facilities
  • Hospitals
  • Schools and after school care
  • Restaurant bathrooms and hand wash areas

Thermostatic mixing valve maintenance

Due to the high-risk groups who use these facilities TMV testing and maintenance needs to be carried out regularly to ensure a consistent hot water temperature.

Required testing schedule

Australian Standard AS4032.3 TMV testing requirements:

  • Thermostat and o-rings replaced every 5 years
  • Testing, inspection and maintenance every 12 months

Recommended servicing and tests

Testing and maintenance of the TMV:

  • Cleaning debris out of the strainer
  • Check non-return valve operation
  • Check discharge temperature at the nearest outlet
  • Test hot and cold water shut off function
  • Replace (every 5 years) or lubricate (yearly) dynamic o-rings
