A burst water pipe is a plumbing emergency that requires fast action to minimise damage, protect your property and get professional repairs underway as quickly as possible.

A burst water pipe can escalate quickly. What starts as “not a big deal” can turn into a plumbing emergency within minutes.

In this article, David MacKenzie, local Pakeham plumber and owner of DMACK Plumbing & Gas, explains what you can do if you have a burst water pipe. The DMACK team deal with burst pipe emergencies of every kind on an almost daily basis. Below, we discuss real-life examples and answer some of the most common questions homeowners ask when they’ve experienced a burst pipe.

In these photos, our customer had a burst pipe behind a brick wall where the water stains were clearly visible on the outside. We had to go through the bricks in order to replace the segment of pipe that had corroded.

How to Tell if a Water Pipe Has Actually Burst

The first signs of a burst water pipe can be easy to miss. A sudden drop in water pressure is usually one of the earliest clues. You may also hear a faint hissing sound coming from a wall or notice a wet spot on the ceiling that gradually gets worse.

Sometimes, though, it’s much clearer, like a pool of water on the floor or water bubbling up in the garden, which can point to a burst pipe underground or a hidden leak.

Small plumbing changes are easy to ignore, but they’re often the first warning signs. Pipes rarely break without leaving a mark. These are often early signs of a burst pipe behind a wall or elsewhere on your property.

How Serious is a Burst Water Pipe?

A burst water pipe is a serious situation and can quickly turn into an emergency.

Water moves quickly, and it doesn’t take long for it to start damaging surfaces outside of the pipe. In a short amount of time, it can soak plaster, ruin floors, and spread into hidden areas you can’t see, like inside walls or under the house. Left untreated, this type of water damage can quickly increase repair costs.

Not only is the water dangerous, but so is what comes after it. Mould can grow in damp areas, and it is much harder and more expensive to remove later.

The risk goes up even more if the leak is near electrical wiring, outlets, or a switchboard. At that point, it becomes a safety issue as well as a property concern.

How Much Should It Cost to Fix a Burst Pipe?

Whenever damage occurs, every homeowner thinks about repair costs.

The cost to repair a burst pipe can range between $200 and $5,000, depending on the size and complexity of the job. Plumbing costs are typically based on factors such as:

• The section or length of pipe that needs to be replaced
• Whether the job is complicated, such as pipes behind walls or underground
• After-hours or emergency plumbing services

As a responsible homeowner, you should understand what you’re paying for. It’s perfectly reasonable to question a quote if it doesn’t seem right.

The Australian Competition and Consumer Commission (ACCC) is one of many organisations that can help you understand your consumer rights as a homeowner and how to get a fair price. There, you can learn about guarantees and report concerns if a business is doing something that feels wrong.

Is a Burst Water Pipe an Emergency?

Yes, a burst water pipe is an emergency and should be addressed immediately. If a pipe bursts, follow these steps:

Step 1: Turn off the main water supply. If you don’t know where it is, it’s usually near the water metre at the front of your property.

Step 2: If there is water near electrical systems or power points, turn off the power if it is safe to do so.

Step 3: Try to contain the water using towels, buckets, or nearby drainage points to limit the spread.

Step 4: Call an emergency plumber.

Who Is Responsible for a Burst Water Pipe?

A pipe can burst for many reasons, and the location of the burst determines who is responsible for repairs.

As a homeowner, you are responsible for fixing burst water pipes within your property.

For rental properties, landlords are typically responsible for urgent burst pipe repairs.

Your local water authority is responsible for burst pipes outside your property line, such as a burst water main in the street.

You can find your local water authority by checking your water bill, visiting your state or council website, or searching online for your suburb followed by “water authority”.

Who Do You Call When a Water Pipe Bursts?

When a pipe bursts, waiting for the water to stop on its own is not an option. You need a local plumber to arrive quickly and fix the problem on-site.

DMACK Plumbing & Gas provides emergency plumbing services for burst pipes, leaks, and other urgent problems after hours in Pakenham and the surrounding areas.

Can a Water Pipe Burst on Its Own?

Yes, water pipes can burst without warning. Materials can weaken over time, and as water pressure builds, the pipe may eventually fail.

Older homes, in particular, are more likely to experience pipe failures due to ageing plumbing systems.

Ground movement, corrosion, rust, and installation issues can all contribute to pipes bursting unexpectedly.

How Likely Are My Pipes to Burst?

Water pipes can burst anywhere and at any time. While there is no definite way to predict a burst pipe, certain properties carry higher risk.

Risks are generally higher if your property:

• Is an older building
• Has ageing or outdated plumbing systems
• Has a history of plumbing problems
• Is built on soil that shifts or moves

High water pressure can also place stress on pipes over time, increasing the likelihood of failure.

Can Pipes Burst if the Water Is Turned Off?

Yes, pipes can still burst even if the water supply is turned off. Some parts of the system may still hold pressure, and temperature changes can cause pipes to expand and contract.

If a pipe is already weakened, it can still fail regardless of whether the water supply is active.

Can I Fix a Burst Pipe Myself?

Handling leaks and plumbing repairs can be complex. While you may be able to slow the leak temporarily, one wrong decision can make the situation worse.

Temporary measures such as tape, epoxy putty, or pipe clamps can help control water until a plumber arrives.

However, proper repairs usually involve replacing damaged pipe sections, checking for hidden water damage, and ensuring everything is sealed correctly. That is when you need a professional plumber, especially if insurance is involved.

How Fast Can a Plumber Fix a Burst Pipe?

The good news is that many burst pipes can be repaired quickly.

If the pipe is easily accessible, repairs may take less than an hour. More complex situations, such as pipes located behind walls or underground, may require additional time for leak detection and repairs.

Instead of waiting and risking further damage, request a quote and get help from a local emergency plumber.

FAQs

How long does it take to dry a house out after a burst pipe?

Drying a house after a burst pipe can take anywhere from a few days to several weeks, depending on how much water has spread and how quickly the damage is addressed. Professional drying equipment and early intervention can significantly reduce drying time and prevent further structural issues.

How long does it take for mould to grow after a pipe bursts?

Mould can begin to develop within 24 to 48 hours if moisture is left untreated. Acting quickly after a burst pipe by removing water and thoroughly drying affected areas is critical to preventing mould growth and avoiding costly remediation later.

Can a burst pipe increase my water bill?

Yes. A burst pipe can cause water to leak continuously, often without being noticed straight away, which can lead to a sudden and significant increase in your water bill. If you receive an unusually high bill, it is worth checking for hidden leaks or arranging a professional inspection.

Will my home insurance cover a burst pipe?

In many cases, home insurance policies cover damage caused by burst pipes, but coverage depends on the specific terms of your policy and whether the damage resulted from sudden failure or lack of maintenance. Always review your Product Disclosure Statement (PDS) or contact your insurer to confirm what is included.

Should I turn off the water when going on holiday?

Yes. Turning off the main water supply before leaving home is a simple and effective way to reduce the risk of major water damage while you are away. Even a small leak can cause significant flooding if it goes unnoticed for days.
