  • Plumbing standards.
  • Plumbing product approval.
  • Fire service inspections.
  • Recycled water - first fix in ground, first fix in wall.
  • Backflow prevention - further information can be found in our fact sheet.
  • Plumbing compliance – investigation of sub-standard performance, complaints and associated enforcement action.
  • Plumbing and drainage inspections of private pipework.
