What to Do When a Flexi Hose or Pipe Bursts
If a flexi hose or pipe bursts in your home, turn off the main water supply at the meter first to stop the flow. If water has reached power points, shut off the electricity at the switchboard and keep off any wet surfaces. Open a nearby tap to release pressure in the pipes, then use towels or buckets to hold back the water. Move furniture and rugs out of the way, take photos for insurance, and call a licensed emergency plumber who deals with burst hoses for a fast repair and a system check.

A burst pipe or a failed flexi hose can flood a kitchen, ruin floorboards and soak the internal walls in a matter of minutes.
These plumbing emergencies tend to happen with no warning, and quick action is the difference between a small repair and a full renovation. In Wollongong, especially in older homes and near the coast, a burst flexi hose is one of the most common causes of water damage we get called to.
What to Do the Moment a Flexi Hose or Pipe Bursts
1. Turn Off Your Main Water Supply
Find the water meter, usually at the front of the property, and turn the valve clockwise to shut off water to the house. In a unit or apartment, look under the kitchen sink or in the laundry for an isolation valve.
2. If Water Has Reached Power Points, Turn Off the Electricity
Do it at the main switchboard. Do not touch wet switches or surfaces if water is near live outlets. Safety comes first, every time.
3. Open Nearby Taps
Run the taps to drain the leftover pressure out of the system. Start with the tap closest to the leak, which slows the water still coming out.
4. Contain the Water
Use buckets, towels or even the outdoor bins to catch the flow. Get rugs, paper, electronics and furniture clear of the area, and dry the floor as fast as you can to keep the damage down.
5. Take Photos for Insurance
Photograph the leak, the water spread and anything visibly damaged. Those photos help if you lodge a claim later.
6. Call a Licensed Emergency Plumber
Call a local licensed plumber who works after hours and knows flexi hose failures. Fast action matters, especially in Wollongong homes with older materials and salt in the air.

Why Flexi Hoses Burst in Wollongong Homes
Braided flexi hoses sit under sinks and basins and behind toilets, connecting the taps to the water supply. Over time the rubber lining inside breaks down and the steel braid corrodes, and coastal conditions like ours speed that up.
In plenty of Illawarra homes, these hoses have not been looked at since the day they went in. Some are over 10 years old, well past their service life. When they go, they usually split wide open and push high-pressure water straight into cabinetry, floor cavities and wall spaces.
The usual causes are:
- Salt air and humidity weakening the fittings
- Cheap or unbranded hoses
- Pressure spikes in old pipework
- No isolation valve at the fixture
Why Every Flexi Hose Should Be Upgraded and Isolated
Replacing the one hose that failed is not enough. If one has split, the others in your home are likely the same age and just as likely to go.
To protect the place properly, your plumber should:
- Replace the lot: swap out any old or unbranded hoses
- Use the right ones: WaterMark-certified, pressure-rated flexi hoses only
- Add mini stop taps: an isolation valve at every flexi hose connection
Those isolation taps let you shut off the water at the source, under the sink or behind the toilet or laundry, without cutting supply to the whole house. So you can stop a burst hose on the spot, even before the plumber gets there.
This is standard practice on new installs now, and worth doing on older homes in suburbs like Figtree, Shellharbour and Woonona, where the old fittings are still common.
Aftercare: What to Do Once the Emergency Is Handled
Once your plumber has sorted the leak:
- Run fans and a dehumidifier to keep mould away
- Pull off the toe kicks or panels from any flooded cabinetry
- Book a whole-home plumbing check for other risk spots
- Add a hose check to your seasonal home maintenance list
If the burst caused structural damage, get onto your insurer straight away with all your evidence.
Local Insight for Wollongong Homeowners
Most of the burst pipe jobs we get called to in Wollongong start with a $10 hose.
A failed flexi hose can do $10,000 of water damage in 15 minutes.
Nearly all of it is preventable. The upgrade is simple, the valves are small, and the difference they make when something goes wrong is huge.
If your home was built or renovated more than five years ago and nobody has checked the hoses, now is the time. Replace them, isolate them, and skip the shock of an emergency you could have stopped in seconds.
