Backflow prevention and TMV testing

Certified testing, servicing, and compliance documentation for backflow prevention devices and thermostatic mixing valves — for commercial premises, strata, and high-risk facilities.

Compliance that protects people — and your facility

Backflow prevention and TMV testing aren’t optional for the facilities that need them. They’re a legal requirement, and for premises serving children, elderly residents, or medically vulnerable people, they’re an ethical one too.

Taro Flow is certified for both backflow prevention testing and TMV testing and servicing. We handle the testing, the documentation, and the submission — so your compliance records stay current and your facility stays protected.

BACKFLOW PREVENTION TESTING

What is backflow?

Backflow is the unintended reversal of water flow in a plumbing system, which can allow contaminated water to flow back into the potable drinking water supply. Backflow prevention devices are installed to stop this from happening — but they must be tested regularly by a certified tester to confirm they’re functioning correctly.

Who needs backflow testing?

Any commercial or high-risk premises with a backflow prevention device installed.

This includes:

  • Childcare centres and schools
  • Aged care and nursing homes
  • Medical and dental practices
  • Commercial kitchens and hospitality venues
  • Strata and mixed-use buildings
  • Any premises identified as a high or medium hazard site by the water authority
TMV TESTING AND SERVICING

What is a TMV?

A thermostatic mixing valve (TMV) blends hot and cold water to deliver a controlled, safe temperature at the outlet. TMVs are installed to prevent scalding — particularly in facilities where vulnerable people are present. Like all mechanical devices, they require regular testing and servicing to remain effective and compliant.

Who needs TMV testing?

TMV testing is required in facilities that care for or serve vulnerable populations:

  • Childcare centres
  • Aged care and nursing homes
  • Disability support facilities
  • Hospitals and medical facilities

Testing and servicing schedule

Minor service — every 6 months
Temperature check, flow test, and fail-safe test.

Major service — annually
Full disassembly, inspection, cleaning, replacement of worn internal components, and temperature calibration.

Not sure what type of testing you need?

Every recommendation is based on what’s right for your business, not what’s easiest to fit or fastest to source. If you’re not sure what you need, that’s fine. An honest assessment is always the starting point. We also keep commercial and strata drains clear with high pressure jetting and CCTV inspections.

Compliance and risk

This is not optional maintenance.

Failure to maintain current backflow and TMV compliance certification can result in regulatory action. More importantly, it creates genuine risk to the health and safety of building occupants.

For facilities serving children, elderly residents, or medically vulnerable people, staying on top of compliance is both a legal and an ethical obligation. Taro Flow provides clear documentation of all testing and servicing outcomes, making it straightforward for facility managers and strata to maintain accurate compliance records.
