What to Do When a Pipe Bursts at Home

A water pipe burst in your house is one of those situations where every minute counts. Water can spread into walls, under floors, and through ceilings incredibly quickly. And the longer it flows, the more expensive the damage gets. 

Here's exactly what to do if a water pipe bursts in your house, step by step, to protect your home and get it sorted quickly.

Quick Answer

• Turn off the main water supply immediately 

• Switch off electricity if water is near any power points, switchboards, or appliances

• Open taps to drain remaining pressure from the pipes

• Document the damage with photos before cleaning up (you'll need this for insurance)

• Call a licensed emergency plumber. Don't attempt a DIY fix on a burst pipe

Step 1: Find Your Water Meter and Shut It Off

The moment you suspect a water pipe has burst in your house, go straight to your main water shut-off valve and turn it off. This stops the flow immediately and limits how far water spreads through your home.

In most Australian homes, the main shut-off is at the water meter near the front boundary of the property, often close to the footpath or driveway. 

Research by QBE Insurance found that 1 in 5 Australians don't know where their water main is, and 18% don't know how to turn it off. Don't be in that group when a burst pipe is flooding your laundry. It’s worth identifying it before an emergency.

Once the water is off, open all your taps and flush the toilets. This drains the remaining water sitting in the pipes and relieves any built-up pressure.

Step 2: Turn Off the Electricity If Needed

If the water pipe burst is near your switchboard, power points, or any electrical appliances, switch off the electricity at the mains too. If you can't safely reach your switchboard because water is blocking the path, leave the area and call an electrician.

Step 3: Take Photos of Everything

Before you start mopping up, photograph the damage. Snap the burst pipe itself (if visible), water pooling on floors, water staining on walls or ceilings, and any damaged belongings.

This is your evidence for an insurance claim. Home insurance generally covers sudden, accidental water damage from a burst pipe, but gradual damage (such as a slow leak) is typically excluded. Clear photos taken immediately help establish that the damage was sudden.

Step 4: Start Removing Water

The sooner water is out of your home, the better. Mould can begin growing within 24–48 hours of water exposure, and structural damage compounds quickly once moisture gets into timber, plaster, and flooring.

Move any wet belongings to a dry area. Mop up standing water, and if you have a wet/dry vacuum, use it. Open windows and doors to get airflow moving through the space.

Step 5: Call a Licensed Emergency Plumber

Once the immediate situation is controlled, call a licensed emergency plumber in Port Hedland right away. A burst pipe isn't a job for DIY pipe tape or temporary clamps.

A qualified plumber will locate the source of the burst (including concealed pipes behind walls or under slabs), assess whether the damage extends beyond the visible break, and carry out a compliant repair. In Port Hedland and the Pilbara, where extreme heat accelerates pipe wear, and UV exposure degrades plastic piping faster than in cooler climates, the repair needs to be done right the first time.

What to expect when the plumber arrives:

• Assessment: They'll identify the exact location and cause of the burst, which may involve leak detection plumbing equipment for concealed pipes

• Repair or replacement: Depending on the pipe condition, they may repair the section or recommend replacing a longer run

• Pressure test: A good plumber will test the repaired line before finishing the job

• Written report: Ask for documentation of the repair for your insurance claim

Why Do Pipes Burst? Common Causes in Australian Homes

Understanding what caused the burst helps you prevent it from happening again. According to QBE Insurance claims data from 2018–2021, burst or blocked pipes are the leading cause of water damage in Australian homes, accounting for 46% of all related claims. 

In Port Hedland specifically, the most common culprits are:

• Old or Corroded Pipes: Ageing copper or galvanised steel pipes weaken over time. If your home is more than 20 years old and hasn't had a plumbing inspection, corroded sections can fail without warning.

• High Water Pressure: Excessive water pressure constantly stresses joints and pipe walls. High pressure is a leading cause of water pipe bursts in houses and is often invisible until something gives way.

• UV and Heat Degradation: Pilbara heat is brutal on plastic pipework, particularly any exposed runs. UV exposure causes PVC to become brittle over time, making it prone to cracking.

• Flexi Hose Failure: Those braided hoses under your sink, behind the toilet, and connecting your dishwasher are a known risk. If yours are more than 10 years old or showing fraying or rust, replace them.

• Tree Root Intrusion: Roots seek out moisture and can penetrate underground pipes, causing cracks that eventually lead to a full break.

How to Prevent a Burst Pipe

Most burst pipes don't come out of nowhere; there are usually warning signs beforehand. Catching them early is far cheaper than dealing with the aftermath.

Watch for these signs:

• A sudden drop in water pressure with no obvious reason

• Discoloured water (rust-coloured water suggests corroded pipes)

• Unexplained spike in your water bill

• Damp patches, bubbling paint, or soft spots in walls or ceilings

• Water sounds when no taps are running

The most effective prevention is a regular residential plumbing repair and inspection schedule. An annual check by a licensed plumber can identify failing sections, worn flexi hoses, and pressure issues before they become emergencies. Our guide to annual plumbing maintenance tasks covers exactly what Pilbara homeowners should be doing each year.

A quick annual inspection takes less than an hour and can save thousands.
