A Thermostatic Mixing Valve, or TMV, mixes hot and cold water to ensure a constant and safe outlet temperature, thus preventing scalding. These valves are particularly important in protecting vulnerable individuals, such as the elderly, children, and people with disabilities, from the harmful effects of excessively hot water.
Thermostatic mixing valve testing is mandatory and must be carried out by a qualified plumber annually. Drain Defenders are the experts in helping you comply with TMV testing requirements in Brisbane and surrounding regions.
Hot water temperature control is a major safety issue in any home or workplace. If a child is exposed to water above 50 degrees Celsius, they can suffer third-degree burns in as little as 1 second.
Thermostatic mixing valves must be installed and serviced annually in accordance with the National Plumbing and Drainage Code AS3500. This means that by law, these valves require maintenance and servicing every 12 months.
It is a requirement of Australian Standards 3500.4:1997 that TMV’s be installed in facilities such as:
- Childcare Centres
- Medical Centres
- Aged Care Facilities
- Hospitals
- Primary and Secondary Schools

TMV Testing- Frequently Asked Questions
What is the TMV test?
A TMV test is a procedure we use to put the valve (TMV) through a process to simulate a loss of flow of one of the water supplies, and also a temperature test. It checks the components of the valve too.
How do you test a thermostatic mixing valve?
To test a TMV valve, we isolate the hot water and then put the valve into a thermos shutdown. After, we repeat this process with the cold side while recording the temperature of the water.
How often should thermostatic mixing valves be tested?
Thermostatic mixing valves must be tested by law every 12 months. Not doing so could result in serious consequences for the property and business owners.
How do I test a TMV?
To test a TMV in Australia, you must hire a licensed plumber with thermostatic valve accreditation provided by state authorities in your jurisdiction. Drain Defenders & Drainage is certified to test your equipment and give a report.
