Final audits

The OTR conducts final audits of on-site plumbing installations to ensure compliance with the National Construction Code Volume 3 (Plumbing Code of Australia).

Plumbing contractors must book a final audit for the following plumbing installations:

If the plumbing installation is selected for a final audit, the plumbing contractor or their representative must be present on-site and have all associated documentation available.

Final audit bookings for residential properties are not required. The OTR will contact plumbing contractors as required for a sample of work for final auditing.

All documentation associated with the plumbing installations (including certificates of compliance and sanitary as-constructed drawings) must be submitted to the OTR within seven days of completing the work.

  • overall compliance with the relevant sections of the Plumbing Code of Australia
  • flood gullies
  • backflow prevention (where required)
  • heated water services (including temperature control devices and energy efficiency requirements)

  • non-drinking water installations (including signage, cross-connection and separation test, identification, loop and valves installed in the correct locations where required)
