Does your business comply with Thermostatic Mixing Valve regulations?
Your TMV (Thermostatic Mixing Valve) will need to be tested annually in NSW in order to remain compliant.
AS 4032.3:2004 states that in the absence of a risk assessment, field testing shall be carried out at intervals of no more than 12 months for thermostatic mixing valves.
A tempering valve or Thermostatic Mixing Valve (TMV) reduces your hot water temperature to the tap, to allow you to meet Australian standards outlined in the Plumbing Code of Australia.
According to AS3498, the delivery of hot water for personal hygiene must be at a maximum of 50°C to prevent burns.
For institutions such as early childhood centers, schools, and aged care or other facilities where the young, sick, aged or disabled could be using hot water, the maximum temperature at the tap must be 45°C.
Do you know what temperature’s your taps are set at?
In 1998, an Australian standard was introduced to regulate hot water temperature storage to a minimum of 60°C (AS3500.4.2 Clause 1.6). This standard is in order to prevent deadly Legionella bacteria, which breeds in warm water under this temperature.
Due to the potential for serious burns at 60°C, the Plumbing Code of Australia also sets standards on the water temperature at the tap.
Did you know?
It only takes one or two seconds for a serious burn to occur at 60°C. When it comes to hot water safety, tempering devices or Thermostatic Mixing Valves (TMV) are the number one way you can save someone from horrific scalding in your business. Specifically for those who are in care facilities such as aged care, hospitals and schools.
As stated on the Australian Building Codes Board (5.2) Testing and maintenance of thermostatic mixing valves, thermostatic mixing valve installation, replacement and maintenance is required to be undertaken by an appropriately licensed plumber. This should be assessed prior to undertaking any testing.
