Backflow Prevention & Testing Brisbane

A backflow prevention device is used to protect potable (drinking) water supplies from contamination or pollution due to backflow. Alliance Plumbing are licensed plumbers that are able to test and install backflow preventers to ensure that any contamination from your supply is not flowing into the local Brisbane water supply system.

Brisbane Backflow Services

You may have a backflow prevention device fitted on your property if you have any of the following:

  • an irrigation system
  • fire hose reels or hydrants
  • a commercial or industrial activity or machinery connected to the mains
  • water outlets in proximity to pollutants, grease traps or chemicals
  • an underground rainwater tank that has mains water backup

If you have a testable backflow prevention device on your property it must be tested annually and the test results forwarded to Brisbane City Council. Reduced pressure zone, double check and some single check valves are testable backflow prevention devices.

Council issues annual reminder notices to prompt owners of premises where testable devices have been installed to arrange testing.
