Backflow Prevention: What Brisbane Property Owners Need to Know
14 March 2026 5 min read
Backflow prevention keeps contaminated water out of Brisbane's drinking supply. If you have irrigation, a pool auto-fill, or a commercial premise, this affects you.
Who Needs One
Any property with irrigation connected to potable mains, pool top-up lines, dental/medical suites, food premises, and multi-storey buildings.
Annual Testing
Testable devices must be tested every 12 months by a QBCC-endorsed backflow tester. Certificates lodge directly with Urban Utilities.
What Failure Looks Like
If your device fails, Urban Utilities can issue a compliance notice and, in extreme cases, disconnect service until rectified.
Frequently Asked Questions
Do I need one for my sprinklers?
Yes — any hard-plumbed irrigation needs at least a dual-check valve, and pop-up systems need a testable device.
