Water Temperature for Personal Hygiene Purposes

Tuesday October 4 2016

Hot water temperatures must reach the right levels to ensure hygiene but the VBA has seen a recent increase in the number of systems installed that do not have the appropriate water temperature control device(s) fitted where the supply is for personal hygiene purposes.

The requirements for tempering the outlets of personal hygiene fixtures apply to all new installations and where the heated water piping is being altered such as in a bathroom renovation.

Although some water heaters may have mixing valves built in to adjust the hot water delivery temperature, these devices are not to be used in lieu of a temperature control device. Only a water heater complying with AS 3498 and marked with the following will be deemed compliant:

"THIS APPLIANCE DELIVERS WATER NOT EXCEEDING 50°C IN ACCORDANCE WITH AS 3498"

If an installation is identified through a plumbing audit as requiring rectification the practitioner will be required to install a water temperature control device(s) or a water heater marked appropriately as part of the rectification works.
