What Causes Pipes to Burst in Brisbane Homes?

Pipes in Brisbane homes typically burst due to a combination of factors, often unrelated to freezing temperatures.

Key culprits include ageing and corroded pipework, especially in older properties, and aggressive tree root intrusion seeking moisture in underground lines. High water pressure, ground movement from weather or construction, and poor installation practices also significantly contribute to pipe failures.

  • Ageing and Corrosion Older galvanised steel or copper pipes degrade over time, weakening their structure.
  • Tree Root Intrusion Roots from established trees infiltrate cracks in underground pipes, causing blockages and ruptures.
  • High Water Pressure Excessive pressure places constant strain on pipe joints and weakened sections, leading to eventual failure.
  • Ground Movement Shifting soil due to weather or construction can stress and damage underground pipes.
  • Poor Installation Substandard materials or incorrect plumbing installation can create weak points prone to bursting.

Okay, so tree roots are a big one. How can you tell if roots are messing with your pipes before you get a full-on burst?

Good question, Sam. The main early signs are slow drainage in multiple fixtures, gurgling noises from toilets, or an odd sewage smell in the yard. A camera inspection is the only sure way to confirm it.

And on the high pressure point – is there a way to check what our house pressure actually is? It feels strong in the shower.

You can buy a basic pressure gauge that screws onto an outdoor tap. If it reads consistently above 500 kPa, it's worth getting a plumber to fit a pressure limiting valve.

Our place is old and has the original galvanised pipes. Is it a case of 'replace everything now' or can you wait for a problem to show up?

It's a judgement call, Leo. Proactive replacement avoids emergency damage, but a good inspection can assess the remaining lifespan. We often recommend a staged plan for peace of mind.
