Thermostatic Mixing Valves in Cairns
TMV installation and annual testing for aged care, childcare and commercial facilities. Full certification included.
Thermostatic mixing valves (TMVs) prevent scalding by blending hot and cold water to a safe, controlled temperature. Ryan installs and tests TMVs for aged care, childcare, healthcare facilities, and residential properties across Cairns — with full certification included.

Common issues
Issues Ryan sees across Cairns
Scalding risk at outlets
Hot water stored above 60°C kills bacteria but can cause serious burns in seconds. TMVs reduce the water temperature at the tap to a safe level while keeping the stored water hot enough to prevent Legionella growth.
Annual testing overdue
TMVs must be tested annually to ensure they're still controlling temperature within the required range. Drift, wear, and scale buildup can cause a TMV to fail over time. Ryan tests and recalibrates as needed.
Compliance requirements
Aged care facilities, childcare centres, and healthcare buildings are legally required to have TMVs installed and tested. Ryan provides the testing, certification, and documentation these facilities need for compliance.
The process
How Ryan helps
Assess requirements
Ryan identifies which outlets need TMVs based on the building type, use, and current regulations. Existing TMVs are inspected for condition and compliance.
Install or test
New TMVs are installed at the required outlets. Existing TMVs are tested with calibrated thermometers to verify temperature output is within the safe range.
Certify & schedule
Ryan issues a compliance certificate documenting all test results. He can set up an annual testing schedule so you never miss a compliance deadline.
FAQ
Common questions
What is a thermostatic mixing valve?
A TMV is a valve that blends hot and cold water to deliver water at a safe, pre-set temperature — typically around 45°C at the tap. It prevents scalding while allowing the hot water system to store water at 60°C+ to kill bacteria like Legionella.
Who needs TMVs installed?
TMVs are required in aged care facilities, childcare centres, hospitals, nursing homes, and some residential settings (particularly where vulnerable people live). They're also recommended for any household with young children or elderly residents.
How often do TMVs need testing?
Annually. The Australian Standard requires TMVs to be tested every 12 months to confirm they're still delivering water within the safe temperature range. Ryan provides testing, recalibration, and certification in a single visit.
What happens if a TMV fails?
A failing TMV can deliver water that's too hot (scalding risk) or too cold (comfort issue, potential bacteria growth). Ryan either recalibrates or replaces the valve depending on the fault, then re-tests to confirm it's within range before issuing the certificate.
