Maintenance for temperature control devices in Australia

Thermostatic mixing valves, tempering valves and end-of-line temperature actuated devices should be regularly tested to ensure that they are operating in accordance with Australian Standards and manufacturers requirements.

Many plumbers are not aware that there is an Australian Standard that specifies the testing of both thermostatic mixing valves and tempering valves at intervals not exceeding 12 months. Also, where required, end-of-line temperature actuated devices should be tested at intervals not exceeding 1 month.

The current standard is AS 4032.3: 2004 Water Supply – Valves for the control of heated water supply temperatures. Part 3 Requirements for field testing, maintenance or replacement of thermostatic mixing valves, tempering valves and end-of-line temperature control devices.

Check with your regulatory authority regarding the application of the Standard and any reporting requirements.

The Australian Standard can be downloaded on-line from SAI Global.
