A tempering valve or Thermostatic Mixing Valve (TMV) reduces your hot water temperature to the tap, to allow you to meet Australian standards outlined in the Plumbing Code of Australia.

As stated on the Australian Building Codes Board (5.2) Testing and maintenance of thermostatic mixing valves, thermostatic mixing valve installation, replacement and maintenance is required to be undertaken by an appropriately licensed plumber. This should be assessed prior to undertaking any testing.

If you have any questions, or are unsure of what is required by your business, give us a call on (02) 4656 4064 or email us at info@crgplumbing.com.au to have your questions answered.

We live in mountain country. This fact makes maintaining a consistent water pressure across the entire community nearly impossible. For this reason, your house must have a water Pressure Regulator installed between your water meter and your first faucet or appliance that uses water. These are usually located inside the house (usually in your basement or crawl space beneath your house) at the point where your water line enters the house from the water meter.

In 1998, an Australian standard was introduced to regulate hot water temperature storage to a minimum of 60°C (AS3500.4.2 Clause 1.6). This standard is in order to prevent deadly Legionella bacteria, which breeds in warm water under this temperature.

GCSD is one of three communities in the nation with a water filtration avoidance waiver. The other two are New York City and San Francisco. The reason we don’t have to filter our water is because it is maintained in a pristine condition from snow pack to your home. This waiver saves our customers well over $20 per month on their water bills because filtration is expensive. The down side to this waiver is that sand and grit that spills off the walls of the Hetch Hetchy Mountain Tunnel can be pumped into our distribution system. We try to intercept most of this grit and sand with a large sand separator before it comes to your home. But, sometimes some sand and grit gets through. If you see some, please call us.

This is a homeowner responsibility, so please avoid damage to your home and appliances by checking your water pressure regulator at least once a year.

Our Service includes testing and supplying you with an asset register and compliance report. We will even set up a recurring reminder for the next test so you don’t have to remember. We make getting your TMV testing easy for you.

For institutions such as early childhood centers, schools, and aged care or other facilities where the young, sick, aged or disabled could be using hot water, the maximum temperature at the tap must be 45°C.

It only takes one or two seconds for a serious burn to occur at 60°C. When it comes to hot water safety, tempering devices or Thermostatic Mixing Valves (TMV) are the number one way you can save someone from horrific scalding in your business. Specifically for those who are in care facilities such as aged care, hospitals and schools.

Due to the potential for serious burns at 60°C, the Plumbing Code of Australia also sets standards on the water temperature at the tap.

Because you may sometimes get sand or grit in your water, it could be trap on the screen of your water pressure regulator. If too much accumulates, it could reduce the effectiveness of your water pressure regulator. For this reason, we ask that you or your plumber inspect and test your water pressure regulator on an annual basis. While inspecting the pressure regulator, your water pressure can be set to your liking for use inside your house. We suggest that you select a pressure between 40 and 50 pounds per square inch (PSI).
