All licensed plumbers in South Australia can book a plumbing and drainage inspection online or by calling the Office of the Technical Regulator (OTR) on 1300 884 055 between 8.30 am and 3.00 pm.

Bookings can be made up to the working day before the day the inspection is required - eg book by 3.00 pm Monday for an inspection on Tuesday. Use the Plumbbooking tab on eCoC to make a booking.

You will receive a booking reference number at the end of your booking. This can be found on your My Plumbbookings dashboard in eCoC. You must record this number on the certificate of compliance.

Recycled water inspections

All recycled water installations in the following suburbs must be inspected by the Office of the Technical Regulator, at the in-ground and in-wall stages of installation:

  • Bowden
  • Campbelltown (Lochiel Park)
  • Mawson Lakes
  • Seaford Meadows.

Recycled water pipework must not be covered or backfilled until it has passed the inspection.

For final fix inspections contact SA Water.

Final audits

The Office of the Technical Regulator (OTR) conducts final audits of on-site plumbing installations to make sure they comply with the plumbing standard published under section 66 of the Water Industry Act 2012.

Plumbing contractors must book a final audit for:

  • commercial/industrial plumbing installations
  • all plumbing installations incorporating an alternative plumbing solution
  • all plumbing installations incorporating a grey water system.

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 for the final audit.

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.

What’s included in a final audit?

Final plumbing and equipment audits may include:

  • 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)
  • venting
  • non-drinking water installations (including signage, cross-connection and separation test, identification, loop and valves installed in the correct locations where required)
  • inspection openings (including raised to surface level where required)
  • visibility of water industry entity water meters and sewer connection points.
