How Often Should A TMV Be Tested In Queensland?

If you have a Thermostatic Mixing Valve, regular testing is recommended. There are many reasons for this, and not getting your TMV tested on a frequent basis could lead to injuries.

If you want to learn how often a TMV should be tested in Queensland, as well as find out more about TMV testing and regulations, read on to find out more.


What Is A TMV?

TMV stands for thermostatic mixing valve. A TMV is one of many valves involved in a plumbing system, in households and businesses across Queensland.

The purpose of a TMV is to combine hot and cold water into one singular, constant stream. This allows you to control the temperature of the water very accurately, preventing scalding.


How Often Should A TMV Be Tested?

In order to ensure that a TMV is working as it should and to comply with regulations, we recommend that you have it tested on an annual basis as a minimum. If you suspect an issue with a TMV, don’t hesitate to book an additional inspection.

If a risk assessment is conducted on a TMV and the assessor concludes that a different testing frequency is recommended, listen to their advice and arrange TMV testing on that basis instead.


Should You Do A TMV Test Yourself?

In theory, you can do a TMV test yourself at home. However, doing a TMV test yourself means you aren’t getting an inspection from a professional that is familiar with potential issues. This means that you could miss signs of damage or wear, which in turn, lead to bigger issues down the track.

It’s always better, and safer, to invest in a TMV test conducted by a licensed and reliable plumber. This way, you can have confidence that the plumbing system at your Queensland property is in good condition and that the TMV is working as it needs to.


What Do TMV Tests Check For?

A TMV test is conducted to check for many things. Firstly, the plumber inspects the TMV itself to see if there are any signs of damage to the valve’s integrity. Another thing that your plumber will look out for is whether the TMV is fitted correctly within the wider system.

They also need to check whether the TMV is fitted to the latest regulatory guidelines as set out by the Plumbing Code of Australia (PCA).

TMV checks also determine whether the TMV is able to adequately protect against scalding by mixing hot and cold water together efficiently.

Following a TMV check, you’ll be informed if the valve meets all of the necessary standards or if any action is required. Such action includes arranging repair work or a new replacement altogether.


How Do You Find A TMV Tester?

When you’re trying to find a local TMV tester that you can put your confidence in, there are a few things to keep in mind. At O’Brien Plumbing Maroochydore, we want to make sure that you find the right Sunshine Coast plumber for you.


If you’re hiring a plumber to conduct a TMV test, you want assurance that they’re going to provide a quality service. Before booking, check their website or social media for any pictures of the work the business has previously completed. Similarly, reading customer testimonials is a surefire way to learn about the quality of service. Also, check that they have the correct license and insurance for the job


TMV testing is offered by various plumbers at a range of different prices. Make sure that you find a plumber that offers the service within your budget. Also, check that there won’t be any hidden costs by getting an upfront quote. Some plumbers also charge for materials on top of the labor fee, so make sure that you are both on the same page before work is completed.


As TMV testing is typically arranged on an annual basis, location isn’t too much of an issue as long as your appointment is made well in advance and is still a commutable distance for the company you choose. If you want all your plumbing services to be provided by one business, however, then it is best to choose one that’s local to you.
