TMV Testing | A Guide To Staying Compliant With Queensland Requirements

As a responsible business or homeowner, it’s important to remain compliant with local regulations and Australian Standards.

Compliance with Queensland’s thermostatic mixing valve (TMV) testing regulations is especially crucial, as TMVs play a vital role in protecting people from scalding hot water.

In this article, we’ll provide you with an easy-to-follow guide on how to stay compliant with regulations if you have a thermostatic mixing valve installed in your home or business, and how Full Flow Plumbing and Drainage can help.

What is a Thermostatic Mixing Valve?

A thermostatic mixing valve (TMV) is a plumbing device that blends hot and cold water to maintain a consistent and safe temperature at the hot water tap. In Australia, TMVs are required in specific situations such as healthcare and aged care buildings.

All new builds, bathroom and ensuite renovations, or when replacing hot water systems and piping installations require a tempering valve or TMV to meet the Plumbing Code of Australian Standards and prevent Legionella growth and scalding.

TMVs are more accurate and longer lasting than tempering valves, but they require specific licensing to be installed by a plumber. Regular servicing is also necessary to ensure the reliability of TMVs and tempering valves.

What Is Thermostatic Mixing Valve Testing?

To ensure that TMVs are working properly, testing must be carried out regularly. This involves checking for leaks, faults, and other issues that could potentially cause harm if left unfixed.

Compliance standards dictate a maximum temperature of 50°C for personal hygiene and 45°C for institutions with vulnerable users, with a minimum storage temperature of 60°C required to prevent Legionella bacteria breeding.

In Queensland, it is a legislated requirement that plumbers who service and test thermostatic mixing valves (TMVs) hold an endorsement. Additionally, Australian Standard 4032.3:2022 stipulates that TMVs be serviced and tested annually.

What Are The Requirements For TMV Testing in Queensland?

Testing must be carried out by a licenced contractor every 12 months;

  • The temperature of hot water should not exceed 50°C at any point during testing;
  • All valves located within residential premises must undergo backflow prevention tests;
  • Automatic shut-off valves must be tested annually;
  • Pressure limiting valves must also be tested every 12 months.

To make sure these requirements are met and your premises remains compliant, always choose a licensed plumber endorsed for TMV testing, who can guarantee their work meets regulatory standards.
