Protect Your Family from Hot Water Burns

Hot water burns are serious. When we have young children in the house, who might play with a tap, or elderly family members who may have slower reactions, we must know that the water at the taps and showerheads in our house is at a safe temperature. A tempering valve is used to control the temperature and prevent scalding.

What’s a tempering valve?

A tempering valve mixes hot water from your cylinder with cold water from the mains or supply tank to deliver water to taps at a safe temperature.  In a home, that temperature must, by law, be below 55 degrees.  In some other places, such as retirement homes and childcare centres, it must be below 45 and 40 degrees, respectively.

Can’t I just turn down my hot water cylinder?

No.  Hot water cylinders are set at a minimum of 60 degrees in order to kill bacteria and ensure the water is healthy. When water drops below this temperature, the likelihood of a person becoming sick from using the water increases.  A tempering valve is fitted to the hot water outlet pipe coming from the hot water cylinder. After the water has been heated enough to kill bacteria, the valve mixes it with cold water to bring it down to a safe temperature.

How do I know if I already have a tempering valve?

Tempering valves are mandatory in new builds and Council-consented jobs involving plumbing.  It is considered good plumbing practice to inform customers if they don’t already have one installed in their home.  You can look for a tempering valve on the pipework of your hot water cylinder.  Most have a black, blue or clear circular plastic cap on them. If you have a valve but your water temperature feels as if it could be too hot, it may no longer work and need to be replaced.
