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.

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!

If it has to do with protecting your workplace against fires and other catastrophic events, we probably sell it. More importantly, we understand how each product plays a role in your overall safety plan.

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.

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:

In any plumbing system there is an intended way for the water to flow. Backflow refers to water that flows in the wrong direction. This causes environmental problems, plumbing issues, and, in the case of fire sprinkler systems, delay the response time to a fire. In a fire protection system, backflow preventers rely on two one-way valves, called check valves, assembled in a series to prevent water from backing up into the supply line. Think of the check valves as one-way gates, only allowing water to flow through them in one direction.Backflow is dangerous for the environment because it can lead to water that has been contaminated with chemicals or other pollutants being reintroduced back to the water table. It is the responsibility of those in the fire protection industry to protect the water supply, and this is regulated by local governing boards.

- 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.

Backflow testing is carried out annually and is usually included as part of fire sprinkler inspection. It is often combined with free flow forward flow testing, which tests to see if gallons per minute required for the sprinkler riser is met.

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.

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.

A deficiency is identified during regular inspections when the devices and components do not meet acceptable standards. Here are a few commonly found deficiencies for backflow devices:

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.

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