Pool Plumbing Basics for Brisbane Homeowners
29 March 2026 6 min read
Pool builders handle the pump and filter — but the plumbing that connects your pool to the house is where compliance issues (and long-term hassles) live. Here's what every Brisbane pool owner should know.
Auto-Fill Line
Any hard-plumbed pool auto-fill needs a testable backflow device — a Watts 007 or Zurn double-check is standard. Annual test required.
Backwash Disposal
Under Queensland regs, backwash water cannot go to stormwater. It must discharge to sewer via a designated point (usually a floor waste or dedicated tundish).
Heat Pump Water Supply
Newer pool heat pumps need a small make-up water supply — plan the line during install rather than retro-fitting.
Frequently Asked Questions
Can I share the auto-fill with my irrigation?
No — they need separate backflow devices in most cases.
