Compliance Testing for Your Plumbing Devices

The Importance of Compliance Testing for Your Plumbing Devices

If your property has thermostatic mixing valves (TMVs), tempering valves, or reduced pressure zone devices (RPZDs) installed, regular compliance testing is an important requirement. 

What Are TMVs, RPZDs and Tempering Valves?

These devices are essential for protecting both people and water quality:

  • TMVs and tempering valves control water temperature to prevent scalding
  • RPZDs (backflow prevention devices) stop contaminated water entering the clean supply

Homeowners (Domestic Properties)

In residential settings, tempering valves and sometimes TMVs are installed to ensure safe hot water temperatures—particularly in bathrooms.

While they’re often “out of sight, out of mind,” over time they can drift out of calibration, wear internally, and stop regulating temperature correctly.

Regular testing and servicing helps ensure your household remains safe and protected, especially for children and older family members.

Businesses & Commercial Properties

For commercial and industrial sites, compliance requirements are more defined.

If your property has TMVs or RPZDs installed, you are typically required to:

  • Have them tested annually
  • Maintain records and certification
  • Ensure they meet Australian Standards and local authority requirements

These are commonly found in workplaces and offices, accommodation and hospitality venues, healthcare or aged care settings, and industrial sites.

Failure to comply can result in regulatory issues, increased liability, and risk to staff, customers, or the public.

Our compliance testing service includes:

  • Full inspection and performance testing
  • Calibration and adjustments where required
  • Identification of faults or wear
  • Issuing of compliance reports and certification

Why It’s Worth Staying On Top of It
