TMV & Backflow Testing

At CNL Plumbing & Drainage, we provide certified TMV (Thermostatic Mixing Valve) and backflow testing services across Hervey Bay, Maryborough & the Fraser Coast, ensuring your systems remain compliant, safe and functioning as required.

​

These systems play a critical role in protecting both public health and water supply. Regular testing is required to ensure they are operating correctly and meeting regulatory standards.

 

We work with commercial properties, managed facilities and sites with compliance requirements, delivering reliable testing and clear documentation.

​

What We Do

We carry out routine testing, inspection and certification of:

• Thermostatic Mixing Valves (TMVs)

• Backflow prevention devices

• Regulated water systems requiring compliance testing

All testing is completed in accordance with Australian Standards and local authority requirements, with certification provided upon completion.

​

Reliable, Ongoing Compliance

We understand that compliance testing is not a one-off job, it’s an ongoing requirement.

Our focus is on making the process straightforward:

• Showing up when scheduled

• Completing testing efficiently

• Providing clear certification records

• Flagging any issues that require attention

If any faults or non-compliant components are identified, we can provide recommendations and carry out rectification works where required.

​

Our Process:

1. Booking of testing in line with compliance requirements

2. Site attendance and inspection of devices

3. Testing and assessment of system performance

4. Certification provided upon completion

5. Recommendations or repairs carried out if required

​

We offer both one-off testing and ongoing scheduled maintenance, depending on your site requirements.

​

If you’re unsure whether your property requires testing or when it is due, feel free to get in touch, we’re happy to point you in the right direction.
