Learn the common causes of burst pipes and what you can do to protect your Perth home.
A burst pipe is one of the most serious plumbing problems a homeowner can experience. Even a small crack can release large amounts of water in a short time, leading to flooded rooms, damaged walls, ruined flooring and costly repairs.
While burst pipes can happen unexpectedly, they are often the result of underlying plumbing issues that develop over time. Understanding what causes pipes to burst can help you identify potential problems early and reduce the risk of significant water damage.
Here are the most common reasons pipes burst in Perth homes and what you can do to prevent them.
1. Ageing and Corroded Pipes
Like any part of your home, plumbing pipes don’t last forever. Over time, pipes naturally deteriorate due to age, corrosion and daily wear. Older homes in Perth may still have ageing pipework that becomes weaker as the years pass.
As corrosion builds up inside or outside the pipe, the material gradually loses its strength, making it more vulnerable to cracks and bursts.
Signs of ageing pipes include:
- Rust-coloured water
- Frequent plumbing leaks
- Visible corrosion
- Reduced water pressure
- Unusual pipe noises
If your home’s plumbing is several decades old, a professional inspection can help identify sections that may need replacement before they fail.
2. High Water Pressure
Many homeowners enjoy strong water pressure, but pressure that is too high can place excessive stress on your plumbing system.
Over time, consistently high water pressure can weaken joints, fittings and pipe walls until they eventually fail.
Warning signs include:
- Pipes making banging noises
- Leaking pipe joints
- Appliances wearing out quickly
- Water spraying forcefully from taps
A licensed plumber can test your home’s water pressure and recommend solutions if it’s higher than recommended.
3. Tree Root Intrusion
Tree roots naturally grow towards sources of moisture. If there are small cracks or joints in underground water pipes, roots may enter and continue growing inside the plumbing system.
As roots expand, they can place pressure on pipes, causing cracks, blockages or complete pipe failure.
Common signs include:
- Slow drains
- Frequent drain blockages
- Soggy areas in the yard
- Unexplained increases in water usage
Professional drain inspections can detect tree root intrusion before major damage occurs.
4. Blocked Pipes
Severe blockages don’t just stop water flowing—they can also increase pressure inside your plumbing system. When pressure builds behind a blockage, weakened sections of pipe are more likely to burst.
Common causes of blockages include:
- Cooking grease
- Hair
- Food scraps
- Wet wipes
- Foreign objects
Keeping drains clear helps reduce unnecessary stress on your plumbing system.
5. Poor Installation or Low-Quality Materials
Not every burst pipe is caused by age. Pipes that were incorrectly installed or fitted with poor-quality materials may fail much earlier than expected.
Problems can include:
- Loose pipe joints
- Incorrect pipe sizing
- Poor workmanship
- Low-quality fittings
- Unsupported pipework
Using licensed plumbers for installations helps ensure your plumbing system is built to last.
6. Ground Movement
Natural ground movement can place stress on underground plumbing pipes over time. Changes in soil conditions, nearby construction work and shifting foundations may cause pipes to crack or separate.
Signs that ground movement may be affecting your plumbing include:
- Cracks in walls or driveways
- Frequent underground leaks
- Wet patches in the garden
- Sudden drops in water pressure
Professional leak detection can help identify underground plumbing problems before they become major repairs
7. Accidental Damage During Home Renovations
Home improvement projects sometimes result in accidental damage to concealed plumbing.
Burst pipes can occur when:
- Drilling into walls
- Digging in the garden
- Installing fencing
- Renovating kitchens
- Renovating bathrooms
Before starting any major renovation, it’s important to know where your plumbing pipes are located.
Warning Signs a Pipe May Be About to Burst
Burst pipes rarely happen without warning. Recognising the early signs allows homeowners to arrange repairs before significant water damage occurs.
Watch for:
- Sudden drop in water pressure
- Damp walls or ceilings
- Water stains
- Unexplained increase in water bills
- Strange pipe noises
- Wet patches in the yard
- Mould growth
- Running water sounds when taps are turned off
If you notice any of these signs, contact a licensed plumber as soon as possible.
What Should You Do If a Pipe Bursts?
A burst pipe requires immediate action to minimise water damage.
If possible:
- Turn off your main water supply.
- Switch off electricity if water is near electrical outlets.
- Drain remaining water by opening taps.
- Move furniture and valuables away from affected areas.
- Take photos for insurance purposes.
- Contact an emergency plumber immediately.
Acting quickly can significantly reduce repair costs and damage to your home.
