Every year around 5,800 people are admitted to hospital for hot liquid burns which totals 45% of all burns across Australia, as stated within the Public Health Association Australia, Injury Prevention Special Interest Group (SIG) "Hot water burns are preventable by fitting temperature reduction valves via hot water tempering devices such as Thermostatic Mixing Valves and Tempering Valves" - Link Below: but is also a legal requirement!

Within the Australian Standards there are temperature management requirements under AS/NZS 3500, 4032, 4032.1, 4032.2 and 4032.3 and the Plumbing Code of Australia. Thermostatic mixing valves, when adjusted to an outlet temperature not exceeding 45°C, are intended for use in health care, aged, childcare, people with disabilities or any other similar at risk situations under AS/NZS 4032.1. Tempering Valves in all other suitable locations to deliver temperatures not exceeding 50 degrees.

RP03 have proven to be top of class for high hazard backflow preventer RPZ applications in NZ. The Reduced pressure zone valve is perfect for both indoor and outdoor applications in NZ.

- Replacement of the temperature actuator every five years from commissioning or as per the manufacturers recommendations.

For more information and or need someone to service your valves please feel free to contact us, we may be able to help, remember in some states you need licences issued by the state authority to service Thermostatic Mixing Valves, where there is no legal requirement in your state to hold a Thermostatic Mixing Valve testers licence ensure that the business doing your testing is a licensed and competent plumber, you cannot touch these valves without the correct licencing.

RP03 have proven to be top of class for high hazard backflow preventer RPZ applications in NZ. The Reduced pressure zone valve is perfect for both indoor and outdoor applications in NZ.

We will concentrate on AS/NZS 4032.3 - 2004 "Water supply -Valves for the control of heated water supply temperatures Part 3: " as we can assume that you already have these types of devices installed as it is law.

- Basically all of the requirements under thermostatic mixing valve testing but full tempering valve replacement every 5 years as you cannot replace the temperature actuator within a tempering valve.

Threaded Stainless steel Reduced pressure zone backflow preventer assembly perfect for all high-hazard backflow protection applications.

Key Points from AS/NZS 4032.3 - 2004, Requirements for field testing, maintenance or replacement of thermostatic mixing valves, tempering valves and end of line temperature control devices.

Water within your hot water unit must be stored at above 60 degrees to reduce the likelihood of Legionella and other bacteria growing within it - this is called maintaining pasteurization temperature within a stored hot water unit, this requirement was bought into law through an addition within the standard AS/NZS 3500 in 1998. So in doing this we brought the requirement for stored water into a temperature range that can burn very quickly:

Thermostatic Mixing Valves and Tempering Valves are temperature control devices installed within a Hot water delivery system to reduce the water down from 60 + degrees to either 45 degrees maximum for Hospitals and Aged Care via a Thermostatic Mixing Valve and maximum 50 degrees via a Tempering Valve for all other applications.
