When a pipe bursts, everything happens at once – water on the floor, ceilings dripping and that sudden jolt of panic. Burst pipes are one of the most common plumbing emergencies in Sydney. What you do in the first few minutes can make the difference between a quick mop-up and a major insurance claim.
This guide steps you through the key plumbing emergency actions to take before your plumber gets to you, so you can minimise water damage.
How to tell if you’re dealing with a burst pipe
Some burst pipes are obvious – you can see water spraying from a wall, ceiling or under a sink. Others start as a steady leak that spreads quietly behind plasterboard or under flooring. Warning signs include:
- A sudden drop in water pressure
- Unexplained damp patches on walls or ceilings
- Wet carpet or swollen skirting boards
- Strange pipe noises such as hissing or gurgling
- A spike in your water bill with no change in use
If you notice any of these, treat it as a burst pipe emergency and move straight into damage control.
Quick checklist: steps before the plumber arrives
Here’s a simple water leak emergency guide you can run through when things go wrong:
- Stay calm and locate the source of the leak if it’s safe.
- Shut off the main water supply or the nearest isolation valve.
- Turn off power if water is near power points, appliances or the switchboard.
- Open taps to drain remaining water from the system.
- Contain the leak with buckets, towels and a temporary fix if possible.
- Move furniture, rugs and valuables away to reduce water damage.
- Call Mates Rates Plumbing for emergency plumbing burst pipe help.
- Take photos and, if required, contact your insurer.
What should you do first when a pipe bursts?
The first thing you should do when a pipe bursts is turn off the water supply at the main shut-off valve or the closest isolation valve to the leak. This stops more water from entering the pipe and keeps the situation from escalating. Once the water is off, you can focus on keeping people safe, limiting the spread of water and arranging urgent burst pipe repair with a licensed plumber.
How to shut off the water valve in a burst pipe emergency
In most Sydney properties, the main water meter and shut-off valve are at the front boundary, often in a small metal or plastic pit. Lift the lid, turn the tap or lever clockwise until it stops and check that water has stopped flowing from your taps.
If the burst is confined to one fixture – for example, under a sink or behind a toilet – you may have a small isolation valve on the pipework you can turn off instead. Knowing where these valves are before an emergency is one of the most useful emergency plumbing tips you can follow.
Make the area safe: electricity and slip hazards
Water and electricity are a nasty combination. If water is running near power points, appliances or the switchboard, turn off power at the main switch as long as it’s safe to reach. Never step into pooled water to get to the board.
Next, reduce slip hazards. Lay towels or old sheets over wet tiles and keep kids, pets and anyone with limited mobility out of the affected area until things are under control.
How do you temporarily fix a burst pipe?
A temporary fix for a burst pipe is only ever a short-term measure, but it can buy time before your plumber arrives. Once the water is off and the pressure has dropped, you can wrap the damaged section with rubber (for example from an old hose), then secure it tightly with a hose clamp, cable ties or strong tape. Set a bucket or tub underneath and pack towels nearby. This makeshift sleeve helps slow the leak so you can focus on cleaning up and preventing further damage.
How to drain the system and stop hidden water leaks
After you shut off the main valve, there will still be water sitting in the pipes. To relieve the pressure and help stop water leaks from continuing, open the cold taps around your property, starting from the highest level and working your way down.
If you’re wondering how to stop water leak issues after shutting off the mains, draining the lines like this is your best next step. Flush each toilet once and, if it’s safe, briefly turn on outside taps. This helps empty the lines so less water can escape from the damaged section.
How do you minimise water damage from a burst pipe?
To minimise water damage from a burst pipe, focus on getting standing water off surfaces quickly and keeping moisture away from your belongings. Move furniture, electronics, soft furnishings and rugs out of the wet zone, then use mops, towels or a wet–dry vacuum to soak up pooled water. Open windows, run fans or air conditioning on dry mode and document the damage with photos in case you need to make an insurance claim. If ceilings start to bulge or sag, keep people out of that room and tell your plumber straight away.
When should you call 000 instead of just a plumber?
Most burst pipes can be handled with fast plumbing help and good damage control. However, call emergency services on 000 first if:
- Water is flowing through live electrical fittings or the switchboard
- A ceiling looks ready to collapse from trapped water
- The burst pipe is linked to a gas appliance or there’s a gas smell
Your safety comes first. Once the immediate danger is under control, Mates Rates Plumbing can deal with the burst pipes themselves.

Simple ways to prevent the next burst pipe emergency
No one can stop every plumbing problem, but a few habits go a long way towards preventing the next late-night call-out:
- Book regular plumbing maintenance and pressure checks
- Replace old galvanised or badly corroded pipes
- Fix small leaks and dripping taps before they worsen
- Know exactly where your water meter and shut-off valves are
- Keep the area around the meter clear and easy to access
- Insulate exposed pipes in cold-prone spots
These steps reduce the strain on your plumbing system and give you a head start if another water leak emergency pops up.

FAQ:
Can I temporarily fix a burst pipe myself?
You can apply a short-term fix, but it should only be used to slow the water down—not replace proper repairs. Once you turn off the water, you can wrap the damaged section with rubber and tighten it using clamps or cable ties. Place a bucket underneath and clear the area of valuables. This temporary fix helps reduce water damage while you wait for your plumber to arrive.
How do I minimise water damage after a burst pipe?
Removing standing water as quickly as possible is the best way to minimise water damage. Move furniture and electronics out of the wet area, soak up water with towels or a wet–dry vacuum and improve airflow by opening windows or using fans. Take clear photos for insurance and avoid entering any room where the ceiling looks swollen or may collapse. The sooner you control the moisture, the easier the clean-up will be.
Where is the water shut-off valve usually located?
Most Sydney homes have the main shut-off valve at the front boundary near the water meter, usually inside a small plastic or metal box set into the ground. Open the lid and turn the valve clockwise until it stops. In some cases, individual fixtures—like toilets or sinks—have small isolation valves you can turn off instead. Knowing where these valves are before an emergency saves you precious time when dealing with burst pipes.
When should I call an emergency plumber for a burst pipe?
Call an emergency plumber immediately if water is flowing uncontrollably, flooding rooms or running near power points and electrical appliances. You should also contact a plumber straight away if the leak is inside a wall, ceiling or underground, as hidden damage can spread fast. If any electrical danger is present, call 000 first, then contact an emergency plumber once it’s safe.
