Why is water coming up through my pavers when it has not rained?

The most likely cause is a burst or leaking water pipe underground. The water service is under mains pressure all the time, so a split keeps pushing water into the soil until it surfaces, often up through the sand joints between pavers. A meter test confirms it: if the meter moves with every tap off, there is a leak.

Should I turn the water off if a pipe has burst underground?

Yes. Turn it off at the meter tap and leave it off until the line is repaired. That stops more water soaking the ground under your paving and foundations, and stops the water bill climbing. You can turn it back on briefly if you need water, then off again.

Can a burst copper pipe be repaired without replacing the whole line?

Usually, yes. The failed section is cut out back to sound copper on both sides and a new length is joined in. Whether the rest of the line needs replacing depends on its condition either side of the break. If it is thin or pitted along its length, more failures are likely.

Who is responsible for a burst pipe between the meter and the house?

The property owner. Sydney Water is responsible for its own pipes and the meter, while the owner maintains the pipes and fittings on their property. Sydney Water may repair the connecting pipe if the problem is less than one metre inside the property boundary.

Why use press fittings instead of soldering for an underground repair?

Soldering needs a dry pipe and a naked flame, which is difficult in a wet excavation beside a house. Press fittings are joined with a hydraulic tool, can be made in damp conditions, and the joint is sound as soon as it is pressed. In our experience it makes for a cleaner, more reliable repair in a hole like this one.

Burst water pipe Maroubra: copper repair

Water coming up through pavers in dry weather is usually a burst water pipe. In Maroubra, old copper had corroded through and was cut out and replaced.

Adam Norton · 14 October 2026

The call from this Maroubra home was simple: water was coming up through the pavers beside the house, and it had not rained. A patch of brick paving that stays wet, or water seeping up between the joints in dry weather, is a burst water pipe underground until something proves otherwise. The water has to come from somewhere, and the line feeding the house runs right under that path.

Greg and I lifted the pavers, dug down to the line and found the burst pipe. The old copper water service had corroded through and split. We cut out the failed section, joined in new copper and put the path back.

Why a burst water pipe shows up as water coming through pavers

A water service is under mains pressure the whole time, whether anyone is using a tap or not. When a buried pipe bursts, that pressure keeps pushing water out into the soil around it, day and night. The ground fills up, and the water finds the easiest way out, which under a paved path is up through the sand joints between the bricks.

That is why the wet patch is a good guide to where the leak is, but not an exact one. Water travels along the pipe trench and through the bedding sand before it surfaces, so the spot where it shows is usually close to the break rather than directly on top of it. Lifting a few extra pavers to follow the line is normal.

Adam Norton kneeling on a tarp beside a house in Maroubra, digging out wet soil under lifted brick pavers to expose a burst copper water pipe — Pavers up, soil out onto a tarp, and digging down by hand to the line. Hand digging matters here, because the pipe is shallow and a spade in the wrong place can damage it further.

Why old copper pipe bursts underground

Copper has been the standard for water services in Sydney homes for decades, and plenty of it is still doing its job. But it does not last forever. Over a long service life copper thins as it corrodes, and once the wall of the pipe is thin enough, mains pressure does the rest. It can start as a pinhole and open into a split.

Buried pipe is harder to keep an eye on than pipe you can see, because there is nothing to inspect until water appears. We have written more about how and why copper ages in this part of Sydney in our Eastern Suburbs pipe corrosion guide.

One burst pipe in an old line does not always mean the whole run is finished. But when the copper either side of the break is in similar condition, it is worth knowing that the rest of the line is the same age and has had the same exposure.

How the burst pipe was repaired

With the water off at the meter, we exposed enough of the pipe to get clean, sound copper on either side of the break. The corroded section was cut out and a new length of copper joined in using press fittings.

Press fittings are joined with a hydraulic press tool rather than a flame. That suits a repair like this one. Soldering needs a dry pipe and a naked flame, and a hole full of wet soil against the side of a house is a poor place for either. A pressed joint can be made in those conditions and holds as soon as the tool releases.

With the joints made, the water went back on and the repair was checked under full mains pressure before the hole was filled. The soil went back in, then the bedding sand and the pavers.

Who pays for a burst pipe on your property

Under Sydney Water's guidance, property owners are responsible for maintaining the pipes and fittings on their property up to where they connect to Sydney Water's network. Sydney Water looks after its own pipes and the water meter. It may repair the pipe that connects a property to its system if the problem is less than one metre inside the property, but a burst on the house side of the meter, like this one, is the owner's to fix.

If an underground leak has been running for a while, the water bill can take a hit. Sydney Water offers a hidden leak allowance, a goodwill credit on the usage charge, where the leak was genuinely hidden, a licensed plumber repaired it and you apply within a year of the repair. Whether a particular leak qualifies is worth checking with Sydney Water directly, and keeping the plumber's invoice helps.

Warning signs of a burst water pipe in Maroubra homes

Maroubra has a lot of older brick homes with gardens, paths and paving laid over the water service where it runs from the meter to the house. That is exactly the layout that hides a leak until it surfaces. These are the signs worth acting on:

Water seeping up through pavers or a path in dry weather. The clearest sign of the lot, and the one that brought us to this job.
A patch of lawn or garden that stays soggy, or grows greener than the rest. Water feeding the soil from below shows up before it pools.
The water meter moving with every tap off. Turn off every tap and water-using appliance, read the meter, and check it again an hour later without using any water. If it has moved, you have a leak.
A drop in water pressure at the taps. A split line loses water before it reaches the house.
A water bill that jumps with no change in how you use water. An underground leak runs around the clock.

If water is coming up right now, turn the water off at the meter tap and leave it off until the line is repaired. That stops the ground getting any wetter and stops the bill running.
