It’s 11 pm. You get up for a glass of water and your socks are wet before you reach the kitchen.
There’s a hiss from under the sink, the cupboard floor is a pond, and the water is walking across the tiles towards the lounge room carpet. That’s a burst pipe, and the next ten minutes matter more than the next ten hours. If it cannot wait, we are a 24/7 emergency plumber, no call-out fee, and Paul answers the phone himself.
If you’ve just typed “burst water pipe what to do” into your phone with one hand and a towel in the other, here’s the short version. Do this bit now.
Turn the water off at the mains first: the tap beside your water meter at the front boundary, usually near the driveway, clockwise until it stops. Then switch off the hot water system if the water is warm, kill the power to any wet area at the switchboard, open a couple of taps to drain the pipes, photograph the damage for insurance, and move what you can. Then call a plumber.
The first 10 minutes, step by step
Step 1: How to turn off the water mains
On most Sydney blocks the water meter sits at the front boundary near the driveway: a short brass pipe standing out of the ground with a dial on top, sometimes hiding in the agapanthus. In the newer estates it’s often in a plastic box at ground level.
The stop tap is on the street side of the meter. Wheel handle: clockwise until it stops. Lever: a quarter turn so it sits across the pipe.
If it’s seized, don’t shear it off with a shifter; it’s Sydney Water’s tap, and if it snaps nobody can stop the water. Water bubbling up in the footpath is Sydney Water’s job too: ring 13 20 90, any hour.
Find this tap now, on a Sunday, in daylight. It’s a nicer job than at midnight in the rain with a torch in your teeth.
Step 2: Turn off the hot water system if the water’s warm
Put your hand in it. If it’s warm, the burst is on the hot side and a full tank will keep feeding it.
Electric: hot water circuit off at the switchboard, so the element doesn’t cook in an empty tank. Gas: control knob to off. Then close the isolation tap on the cold pipe into the bottom of the tank.
Step 3: Kill the power near wet electrics
Water through a light fitting, near a power point, or down a wall with a switch on it: turn off the main switch at the switchboard, and don’t stand in water to do it. If the switchboard itself is wet, call an electrician.
Step 4: Open the taps and drain the pipes
The pipes are still full. Open the lowest tap (usually the garden tap out the front) and one at the far end of the house to let air in, and the leak drops to a dribble inside a minute.
Step 5: Photograph everything before you mop
I know the instinct is towels. Phone first: video the water, where it’s coming from, and everything it has soaked. Then keep the failed part; a split flexi hose in a zip-lock bag is the best friend your insurance claim will ever have.
Step 6: Move what you can and start drying
Rugs up, furniture legs onto foil or a jar lid, electronics and paperwork up high. Then towels, mop, and every window and fan going, because in a Sydney summer wet carpet turns into a mould farm inside a couple of days.
What usually bursts (and why flexi hoses top the list)
After thirteen-odd years under sinks, the pattern is pretty clear.
Flexi hoses
The braided hoses connecting your taps, toilets and washing machine to the wall. The braid corrodes or frays, the rubber inside bulges through, and one day it lets go. A flexi hose burst under a kitchen sink is a garden hose running flat out inside your cupboards until someone notices, which, if you’re at work, is nine hours.
Bleach stored against them speeds up the rust. In the newer estates, Oran Park say, there’s one under every vanity and behind every toilet, all fitted the same week, so they’ll all get old the same week. I’d pencil that in.
Old galvanised and copper pipe
Plenty of older homes around Liverpool and Fairfield still have original galvanised steel pipe, which rusts from the inside until a pinhole opens. Copper isn’t immune either: a copper pipe leak usually starts as a pinhole from pitting, a joint that was never soldered properly, or a thin spot on a bend where the water has been sanding it for fifty years.
Tree roots and clay on the water service
The water service runs from the meter to the house, and around South-West Sydney it sits in reactive clay that swells when wet, shrinks when dry, and shoves the pipe around every season. Add a big street tree looking for a drink and joints pull apart; the tell is a patch of lawn that never dries. Roots do the same to sewer pipes, only smellier.
Frost and water hammer
Frost is rare in Sydney, but out around Camden and the Macarthur hinterland the clear winter nights get properly cold, and an exposed pipe to a garden tap can freeze, expand and split. You find out when it thaws.
Water hammer, the bang in the wall when a tap shuts off fast, is a little shock through the joints every time. Fix the hammer and you’ve fixed a burst that hasn’t happened yet.
Burst pipe or hidden water leak? Do the meter test
A burst pipe announces itself. A hidden water leak doesn’t; most people meet theirs through a high water bill, a damp patch on the ceiling that comes and goes, or a warm spot on the slab.
The meter test costs nothing:
- Turn off every tap inside and out, and don’t run the dishwasher, washing machine or a toilet.
- Photograph the dial on the water meter.
- Wait thirty minutes.
- Photograph it again.
If the numbers moved, or the little star or triangle on the dial is turning, it’s leaking on your side. Sydney Water looks after the pipe up to and including the meter, and from there in it’s yours.
Toilets are the usual suspect: a few drops of food colouring in the cistern, and if the bowl changes colour without a flush, that’s your leak. If it’s not the toilet, proper water leak detection earns its money: acoustic listening gear, thermal imaging for hot water lines under a slab, and pressure testing one section of pipe at a time.
What counts as a plumbing emergency (and what can wait till morning)
Here’s the honest bit that costs me money. A 24 hour plumber and an after hours plumber are the same bloke charging roughly 50 to 100 per cent more for the sleep he isn’t getting. Once the mains is off, most of the emergency is over.
What counts as a plumbing emergency comes down to one question: is it still doing damage, or could it hurt someone? If yes, call now. If no, call at 7 am and pay the day rate.
| Situation | Call now or wait? | Why |
|---|---|---|
| Water still flowing and you can’t find or turn the mains | Call now | Every minute is more damage |
| Water near the switchboard, lights or power points | Call now, plus an electrician | Water and electricity don’t negotiate |
| Sewage backing up into the house | Call now | Health risk |
| Hot water system split and flooding | Call now | Power or gas and inlet off first, if it’s safe |
| Mains off, water stopped, you can manage overnight | Can wait till morning | Standard rate, not after hours |
| Flexi hose burst under a sink or toilet with its own isolation tap | Can wait | Little tap off, bucket, mop, book in the morning |
| Wet patch on ceiling that’s damp but not dripping | Can wait, but this week | Before it’s a wet ceiling on the floor |

Burst pipe repair cost and emergency plumber cost in Sydney
Sydney 2026 price guides put burst pipe repair at roughly $230 to $920, with most plumbers around $140 an hour plus a call-out fee of about $69 to $170. The emergency plumber cost is the part that stings: 50 to 100 per cent more, so an after hours visit with an hour or two of work commonly lands between $400 and $900 all up. Every job is quoted on inspection; the full spread is in the price guide and my own cost breakdown.
Access sets the price. Leaking pipe repair on a flexi hose under a sink is quick; a copper pipe leak inside a tiled wall means opening the wall; a water service under the driveway means digging, which we do with our own mini excavator.
Insurance claim: burst pipe damage is usually covered, the pipe often isn’t
Most home and contents policies cover a sudden escape of water (a burst pipe or flexi hose letting go) and the damage it does to carpet, plaster and cabinets, but often not the pipe itself or a slow leak that’s been going for months, which gets filed under wear and tear. Check your PDS.
What helps: the photos from step 5, the failed part in a bag, and a plumber’s invoice that says what failed and why (we write that up; the assessor always asks). Some policies also cover the cost of finding a hidden leak under “exploratory costs”, so ask.
My two cents: check your flexi hoses once a year
I’ll die on this hill: check your flexi hoses once a year and replace them every five to ten years regardless. It’s a twenty-dollar part, it takes ten minutes, and I’d put money on it being the most common indoor flood in South-West Sydney.
Look for rust spots or fraying on the braid, a bulge, a kink, or any dampness. Fitting a new one: hand tight and a quarter turn, no kinks, write the date on masking tape around it, and move the bleach to the laundry.
And turn the mains off when you go away for more than a weekend. It’s free.
When to call a plumber
Call now if water is still running after you’ve tried the mains, if it’s near electrics or sewage, or if you can smell gas. Call in the morning if it’s isolated and drying; you’ll pay less, and I’m more charming at 7 am than at 2 am.
Either way, use a licensed plumber; NSW requires it, and you can check a licence through NSW Fair Trading.

Frequently asked
How do I turn off the water to my house in Sydney?
Find your water meter at the front boundary, usually near the driveway or front fence. It's a short brass pipe with a dial on top, or a plastic box at ground level in newer estates. The stop tap is on the street side of the meter: turn a wheel handle clockwise until it stops, or turn a lever a quarter turn so it sits across the pipe.
Is a burst pipe a plumbing emergency?
It is while water is still running. Once you've shut the mains and the water has stopped, most burst pipes can wait until morning. With us the rate is the same day or night, so the only question is whether you can manage without water until then. Call straight away if you can't stop the water, if it's near electrics, if sewage is involved, or if a hot water system is flooding.
How much does it cost to fix a burst pipe in Sydney?
Sydney 2026 price guides put burst pipe repair at around $230 to $920, depending on where the pipe is and how hard it is to reach. A flexi hose under a sink sits at the low end; a pipe inside a wall or under a slab sits at the top. After hours work costs roughly 50 to 100 per cent more. Every job is quoted on inspection.
Does home insurance cover a burst pipe in Australia?
Usually the damage, not always the pipe. Most home and contents policies cover a sudden escape of water, such as a burst pipe or flexi hose, and the damage it does to floors, walls and cabinets. Slow leaks and wear and tear are often excluded. Photograph everything, keep the failed part, and get a plumber's invoice that states the cause. Check your policy's PDS.
How do I know if I have a hidden water leak?
Turn off every tap and appliance, photograph your water meter, wait thirty minutes without using water, and check it again. If the numbers or the small dial have moved, water is leaking somewhere on your side of the meter. Other signs are a high water bill, a wet patch on the ceiling, a warm spot on the floor, or a patch of lawn that never dries.
How often should flexi hoses be replaced?
Check them once a year and replace them every five to ten years, sooner if you see rust spots, fraying, bulging or a kink in the braid. They're a cheap part and one of the most common causes of indoor flooding. Write the install date on the hose with tape, keep cleaning chemicals away from them, and turn the isolation taps off when you go on holiday.
