Keep your staff protected by ensuring that your Thermostatic Mixing Valves (T.M.V) work effectively and meet government regulations!

At Banjo Nominees, we provide a range of industrial TMV testing and maintenance services to keep your workplace safe and protect your business from costly shutdowns and damages.

A TMV combines hot and cold water to ensure running water is at a safe and constant temperature, preventing scalding and also the deadly legionella bacteria which breeds in water. To remain compliant with industry regulations, commercial buildings must have TMVs fitted with a maximum temperature of 50°C to prevent burns. Schools, childcare centers and facilities that provide care for aged, sick or disabled individuals should only have a maximum temperature of 45°C. TMV testing is a requirement to ensure that temperatures remain safe for commercial use.

We have long-standing plumbing maintenance contracts with major public hospitals throughout Melbourne and are certified by Australian Government Standards to carry out the procedures to the highest standard.

Our professional and experienced team provides TMV testing and premium maintenance solutions to guarantee that your T.M.V will comply with industry regulations. Contact us today to discuss thermostatic mixing valve testing across Melbourne.

Thermostatic Mixing Valve Testing & Installation FAQ’s

What is a thermostatic mixing valve?

The water from a hot water heater is too hot to come directly out of the fixtures as it could cause scolding. A thermostatic mixing valve (TMV) is a plumbing device that blends hot and cold water together to supply your building with a constant reliable hot water temperature from the hot water tap.

A thermostatic mixing valve device blends hot and cold water to ensure that the water supplied to your building is constant and safe. A TMV is important as it maintains safe water temperature standards, which help to avoid potential burns, scalding or even thermal shock. This device is used in residential and commercial settings.

A TMV has a thermal-sensitive component which contracts and expands in response to fluctuations in the temperature of incoming cold and hot water maintaining the safe delivery temperature set by a mechanical plumber.

A thermostatic mixing valve can be installed at the water heater itself or at any specific plumbing fixture that requires a controlled water temperature. A licensed mechanical plumber can help you find an appropriate location for the TMV and also install the device for you.

A tempering valve is typically installed in smaller scale standard domestic water heating situations. A TMV responds quicker to pressure and temperature variations than a tempering valve. It is usually fitted in instances where there is a demand for more accurate control of the water temperature, as well as in larger commercial applications, like hospitals.
