Check the valve.
Understand the system.

A TMV forms part of the heated-water installation. The hot and cold supplies, connected outlets and valve condition can all influence performance, so a reported temperature change needs assessment.

We review the installation and discuss appropriate testing and servicing for the model. Sediment, worn components or supply issues may need attention. Any repair or replacement work is explained before proceeding.

If the issue also involves the water heater, see hot water repairs. Other supply fittings may need pipe and valve assessment.

Discuss TMV testing
Service schedules / documented findings

Plan the maintenance.
Keep the records clear.

The servicing interval and documentation should reflect the manufacturer’s requirements and the type of property. A facility may also have its own operating and recordkeeping requirements. Share those details when booking.

We explain the findings, maintenance carried out and any recommended follow-up work. Ask which testing or certification documents are included so the defined plumbing task is clear.

The report identifies the system and work assessed. If the property also needs backflow device testing, tell us so it can be planned as a separate item.

FAQs

Your TMV questions, answered.

What does a TMV do?

A thermostatic mixing valve blends hot and cold water to control the temperature supplied to connected outlets. It forms part of the property’s heated-water system and needs suitable installation and maintenance.

Can you install and service TMVs?

Yes. Send the valve or proposed product details, property use and connected outlet information. We discuss the relevant installation, testing or maintenance scope before confirming the work.

How often should a TMV be tested or serviced?

The schedule depends on the manufacturer’s instructions and applicable property or facility requirements. Share the previous report and any maintenance plan so we can discuss the appropriate booking.

What if the outlet temperature changes unexpectedly?

Keep an outlet out of use where the temperature presents a risk and tell the property or facility manager. Arrange an assessment. Do not adjust or bypass the valve yourself.

Is a TMV the same as every other tempering device?

No. Different temperature-control devices have different functions and applications. The appropriate device depends on the installation and relevant requirements. We assess the system rather than treat all valves as interchangeable.

What paperwork is included?

We discuss records for the defined testing and servicing, along with any required certification scope. Tell us what the property or facility needs before booking so documentation requirements are clear.

Will the testing affect water use at the property?

It can affect connected outlets while the work is carried out. We discuss access and any interruption with the property contact so the visit can be coordinated.

Which areas do you service?

We are based in Coffs Harbour and work across the Coffs Coast, including Sawtell, Toormina and Woolgoolga. Send the address and project details so we can confirm availability for your property.
