Burst Pipe in Canberra: What to Do in the First Ten Minutes

Work through this in order. The whole sequence takes about five minutes and it has more effect on the final bill than anything a plumber does afterwards.

1. Turn the water off at the meter on your front boundary. The tap is on the house side of the meter. Turn it clockwise until it stops.
2. Switch the hot water unit off. Electric and heat pump units go off at the breaker. A gas unit has an isolation valve on the gas line beside it, and if you are not certain which one that is, leave it and tell the plumber when they arrive.
3. Open the lowest cold tap in the house, usually a laundry tub or an outside tap, to drain what is left in the pipes.
4. If water is anywhere near powerpoints, light fittings or the switchboard, turn that circuit off, but only if you can reach the switchboard without standing in water. If you cannot, stay out of the room and ring Evoenergy on 13 10 93.
5. Photograph everything before you touch it. Wet carpet, the ceiling stain, the pipe itself, the water level. Photos taken after the clean-up are worth very little to an insurer.
6. Ring a plumber and say the water is already off. That changes how the job gets scheduled.

Where is the water meter on a Canberra block?

On most Canberra properties the meter sits in a plastic or concrete box at ground level on the verge near your front boundary, often within a few metres of the driveway. Lift the lid and you will see the meter and a tap on each side of it. The one on the house side is yours to use.

Two things make this harder than it sounds at 2am. The box is usually full of grass and sometimes half buried, and the tap can be stiff enough that you need a shifter. Find yours on a Saturday afternoon when nothing is wrong, clear the grass out, and check the tap actually turns. That is ten minutes now that saves a flooded lounge room later.

Icon Water owns the meter and the pipework up to it. If the leak is on the street side of the meter, if the meter itself is leaking, or if the box is flooded and you cannot get to the tap, ring Icon Water faults and emergencies on 02 6248 3111. They run that line 24 hours. Anything on the house side of the meter is yours and needs a licensed plumber.

Why do pipes burst in Canberra?

Frost, mostly. The Bureau of Meteorology puts the mean July minimum at Canberra Airport at 0.1 degrees, with June at 0.9 and August at 1.2. Water in an unprotected pipe freezes overnight and expands, and the pipe splits. You often will not know until mid morning, because nothing comes out while the ice is still in there. The flood starts when it thaws.

The runs that fail first are predictable:

• Outdoor taps and the riser feeding them, particularly on the south and west sides where the sun does not reach.
• Pipes crossing an unheated roof space, which is most of the older housing stock.
• Irrigation and garden lines nobody drained before winter.
• Pipework under a raised floor with open subfloor vents.
• The relief line off a hot water unit standing in the open.

Frost is not the only cause. Older copper in 1960s and 1970s homes thins out over decades, and pinhole failures in it are common through the Inner South and Woden. Water hammer, the bang you hear when a washing machine valve slams shut, fatigues joints over years. Ground movement on reactive clay soils cracks buried lines. None of those care what month it is.

Preventing the frost ones is a separate job and we have covered it properly in the Canberra winter plumbing guide, which goes through lagging, drip taps and what to do before the first hard frost.

How much does a burst pipe cost to fix in Canberra?

A burst pipe repair generally runs $200 to $600 depending on where the pipe is and how hard it is to reach. One under the kitchen sink is at the bottom of that. One inside a wall cavity or under a slab is at the top, because most of the labour goes into getting to it and making good afterwards.

The bigger variable is the hour you ring. Callout fees in Canberra sit between $80 and $200 inside business hours, and climb from there:

Those figures are the same ones set out in our guide to emergency plumber costs in Canberra, and the parts and labour for the repair sit on top of the callout.

Worth saying plainly: the plumbing is usually the cheap part. Drying out a saturated floor, replacing gyprock and getting carpet lifted and relaid costs multiples of the pipe repair. That is why the first ten minutes matter so much.

Does home insurance cover a burst pipe?

It depends on your policy and on how the failure happened, so read the wording rather than taking anyone's word for it. Two sections decide most claims: the escape of liquid cover, which deals with sudden water damage, and the gradual damage exclusion, which is where slow leaks that have been going for months usually land. Many policies pay to repair the damage the water caused without paying to replace the pipe that failed.

Whatever your policy says, insurers ask for the same things. Dated photographs taken before the clean-up. An itemised invoice from a licensed plumber describing the cause as well as the fix. A record of when you noticed it and what you did. Ask your plumber to write the cause on the invoice while they are still standing there, because getting that added three weeks later is harder than it should be.

What can you do while you wait for the plumber?

Once the water is off, the job is limiting damage. Lift rugs and get furniture off wet carpet. Move anything valuable up off the floor. Open windows and doors so the room starts drying, and get a fan on it if you have one and the power in that area is safe.

Stay out of any room where water is near electrical fittings until that circuit is off. And leave the burst itself alone. Tape and rags on a pressurised line hold just long enough for you to turn the water back on, then let go while you are out of the room.

Is a burst pipe always an emergency?

Not always. Ring straight away if you cannot stop the water, if it is running near electrical fittings, if a ceiling is bulging or holding water, or if the mains being off leaves the house with no usable water. Those do not improve overnight.

If you have isolated the burst at a single fixture and the rest of the house works normally, a booked visit the next morning costs less and gets the same result. Our post on when to call an emergency plumber works through the same call for other faults.

We run 24/7 emergency plumbing across Canberra, including the newer estates out through Molonglo Valley and the older stock in Weston Creek, where the frost sits longest in the mornings. Whatever time you ring, you get the price before the repair starts.
