Prevent Severe Burns with Annual Tempering Valve Testing & Certification Services
For nearly five decades, Whywait Plumbing Services has been the go-to local Gold Coast plumber for hot water tempering valve solutions. Established in 1976, our skilled team consistently delivers dependable and professional services to guarantee your safety and comfort.
As Queensland law mandates, hot water in personal hygiene spaces such as bathrooms must be controlled using a hot water tempering valve or a thermostatic mixing valve. This regulation ensures that hot water temperatures do not surpass 50° C at the basin, bath, or shower taps.
Hot water at 60° C can inflict severe third-degree burns within just one second. By installing a tempering valve, you can substantially minimise this risk as it regulates the hot water delivery temperature to a safer 50° C at hot taps.
People with disabilities, older adults, and children are more susceptible to scalding due to their reduced reaction times and thinner skin. Consequently, facilities such as childcare centres and aged care accommodation facilities catering to these individuals must guarantee that hot water delivery temperatures at every bathroom tap remain below 45° C.
You can trust Whywait Plumbing Services for all your installation, maintenance, and repair needs, ensuring your safety, comfort and satisfaction.
Protect Your Family From The Risk Of Serious Burns As Hot Water Burns Like Fire
In recent times, licensed plumbers have been entrusted with the responsibility of ensuring the safe delivery of hot water for domestic bathrooms used primarily for personal hygiene purposes. Recent litigation reinforced this obligation and required licensed plumbers to take a “deed of care” for their clients seriously.
This is why Whywait Plumbing Services carries tempering valves in all our service utes, which can only be installed, tested and certified by licensed plumbers as they are mandatory requirements for ensuring your safety.
Since 1995, it has been a legal requirement to install tempering valves in the following situations: for new hot water system installations in new homes, for replacements or upgrades of an existing hot water system, and for relocating an existing hot water system to a new location on the property. Homes built before 1995 may still have hot water delivered at a dangerous temperature of 70°C or above.
Hot Water Tempering Valves are designed to blend hot and cold water to provide mixed water at a constant temperature. The valve incorporates a temperature-sensitive element that expands and contracts based on the water temperature flowing across it. This action of the element moves a piston that shuttles between the hot and cold ports, maintaining a constant outlet temperature and significantly reducing the risk of hot water scalding accidents.
At Whywait Plumbing Services, we are committed to ensuring your safety and comfort by providing expert installation, testing, and certification of tempering valves.

Servicing, Testing & Certifying Hot Water Tempering Valves
Valves associated with a hot water service are exposed to extreme operating conditions and require periodic maintenance, servicing, and replacement. Hot water tempering valves, in particular, are critical components that require regular field testing and maintenance to minimise the risk of accidents. In accordance with AS 4032.3:2022, field tests must be carried out at intervals not exceeding 12 months.
Hot water is increasingly becoming a legal concern for plumbers, business premises, homeowners, and property investors as they have a duty of care to ensure the safety of hot water delivery. However, clarifications in AS/NZS 3500.5-2012 no longer apply as that standard has been withdrawn.
In its place, an ill-defined guideline in Appendix M of AS/NZS 3500.4:2021 provides guidance on the operation and maintenance of a heated water system. It is, therefore, essential to engage the services of experts such as Whywait Plumbing Services to ensure compliance and minimise the risk of accidents.
M3 MAINTENANCE OF HEATED WATER SERVICES
Heated water services should be maintained in accordance with the following:
(a) Water treatment units Where installed, water treatment units should be inspected periodically to ensure proper operation.
(b) Water vessels and tanks All vessels and tanks should be inspected and cleaned periodically, and in accordance with any requirements of the regulatory authority.
NOTE: The frequency of periodic cleaning depends upon the quality of the supply water, design, materials of construction and the pipe system. Combinations of materials giving rise to corrosion should be avoided.
(c) Valves The following valves should be inspected periodically to ensure proper operation:
(i) Temperature/pressure-relief valves.
(ii) Expansion control valves.
(iii) Thermostatic mixing valves.
(iv) Tempering valves.
(v) Other associated valves/devices
Field-Testing Requirements for Tempering Valves in AS 4032.3:2022
From a legal perspective, property owners are legally responsible for ensuring that routine maintenance is carried out on their hot water systems.
AS 4032.3:2022 outlines the minimum requirements for field testing, maintenance, and replacing thermostatic mixing valves, tempering valves, and end-of-line temperature-actuated devices. For property owners with tempering valves, this means that they must comply with the minimum requirements of AS 4032.3:2022 in the event of a hot water scalding incident.
Thermostatic mixing valves and tempering valves require field testing every 12 months, as per Table 1 of AS 4032.3:2022. Testing and servicing should be undertaken in accordance with Appendix C.
As a property owner, it is essential to engage the services of experts such as Whywait Plumbing Services to ensure compliance with the legal requirements and minimise the risk of accidents.
METHOD FOR TESTING AND MAINTAINING TEMPERING VALVES

This Appendix sets out the sequence for determining the in-service performance of line strainers and non-return valves either integral with, or independently fitted in, installations of tempering valves, and of checking the temperature of water delivered to ablution points.
C2 PRINCIPLE
The valve is inspected, tested and maintained in accordance with Section 2.
C3 APPARATUS
The following apparatus is required:
(a) A temperature measurement device in accordance with Clause 2.3.
(b) Suitable tools and pressure gauges to perform the required work.
(c) Any other apparatus that is recommended by the manufacturer of the device.
C4 PROCEDURE
The procedure to be followed shall be in accordance with the manufacturers instructions. The minimum inspection and testing shall include the following:
(a) Strainer cleanliness.
(b) Non-return valve operation.
(c) Discharge temperature measured at the nearest ablution outlet to the valve for high and low flow.
(d) Where practical to carry out the test, the cold water shut-off operation.
Where a device is not functioning in accordance with the intended application, it shall be repaired in accordance with AS 4032.2 or replaced.
C5 REPORT
The following shall be reported:
(a) The model, manufacturer and identification of the valve.
(b) Temperatures recorded during test.
(c) Details of test, maintenance and parts replaced.
(d) Location of the valve
(e) Reference to this test method, i.e., AS 4032.3:2022, Appendix C.
Tempering Valve Testing Report
The importance of compliance with AS 4032.3:2022 testing requirements cannot be overstated for plumbers and property owners as it mitigates their potential legal liability risk in case of hot water scalding incident.
At Whywait Plumbing, we understand the critical role that tempering valves play in ensuring your safety. Our qualified and licensed plumbing technicians are trained to test and maintain your tempering valve. An annual report is essential, and failure to obtain one could leave you liable in case of burns resulting from your hot water delivery. Furthermore, the absence of an annual report could also put your insurance coverage at risk.
You can trust Whywait Plumbing to provide the necessary testing and maintenance services to ensure your safety and minimise the risk of accidents.
