Burst & Leaking Pipe Repair

Honestly, few things wreck a day quite like a burst pipe. One minute everything's fine, the next you've got water all over the floor wrecking your carpet, ruining the walls, and sending your Water Corporation bill through the roof while you're scrambling around trying to figure out what happened. Leaks that start slow aren't any better either. They just do all their damage in secret, chewing through timber and growing mould somewhere behind the plaster you can't see for months on end.

We've got licensed plumbers based right here in Canning Vale who deal with burst and leaking pipes all across Perth's south-east. Here's what usually goes wrong, what you should do if it happens to you in the middle of the night, and how we go about sorting it.

What causes pipes to burst or leak

There's a few reasons pipes give up the ghost, and figuring out what went wrong is the first step to making sure it doesn't happen again.

• Age and corrosion in older galvanised steel or copper pipework, common across Perth's established suburbs.
• Ground movement as WA's sandy, reactive soils shift with the seasons, stressing joints and pipe runs.
• High water pressure straining fittings and joints over time.
• Tree roots wrapping around and crushing underground pipes.
• Physical damage from digging, reticulation work or renovations.
• Poor original installation or degraded joints and seals.
• Freezing, which is rare in Perth but can affect exposed pipes on the coldest winter nights.

What to do when a pipe bursts

Speed is everything here. The faster you act, the less stuff gets ruined. Here's the rough order of things:

• Turn off the water at the mains. Your main stop tap is usually near the front boundary by the water meter, or where the supply enters the house. Turn it clockwise to shut it off.
• Turn off the hot water system if the leak is on the hot side, to stop it drawing in water.
• Switch off power to any area where water is near electrical outlets or the switchboard.
• Drain the pipes by opening the lowest taps in the house to relieve pressure.
• Move valuables and soak up water to protect your floors and belongings.
• Call a licensed plumber.

Seriously, find where that mains tap is before you actually need it. Saves a whole lot of panic. We've put together a proper checklist in our guide on what to do in a plumbing emergency if you want the full rundown.

Finding the leak

Not every leak is obvious. A burst under a slab, behind a wall or underground in the garden can do serious damage before you spot a drop of water. Signs of a hidden leak include an unexplained jump in your water bill, damp patches or bubbling paint, a musty smell, reduced water pressure, or the sound of running water when everything's turned off.

Rather than cutting open walls to hunt for the source, we use specialist water leak detection equipment, including acoustic and thermal tools, to pinpoint the exact spot. That means a smaller, targeted repair and far less mess. If you suspect a hidden leak, our guide to the signs of a hidden water leak will help you spot it early.

How we repair burst and leaking pipes

Once we've located the fault, the right repair depends on the pipe and the extent of the damage.

Spot repairs

Got a single burst or leaking section? We cut out the damaged part and replace it with new pipe and fittings. This is the quickest, most economical fix for an isolated failure in otherwise sound pipework.

Repiping

When pipes are old and corroded and blowing out in different spots, fixing one leak really just shoves the trouble further along the line. Replacing a run or repiping a section is the smarter move long-term, even though it is a bigger job. It stops the cycle of leaks and all the water damage that goes with them. We'll always be upfront about whether a repair or a repipe makes better sense for your home and budget.

Underground and slab repairs

Leaks under a slab or buried in the yard need careful handling. With accurate detection, we can often access and repair the exact spot with minimal disruption, and we'll restore the area properly afterwards.

Why use a licensed plumber

In Western Australia, pipe repairs must be carried out by a licensed plumber, and it's easy to see why. A poorly made joint can fail again within weeks, and mistakes on pressurised water lines cause exactly the flooding you're trying to avoid. A licensed plumber gets the repair right, uses compliant materials, and stands behind the work. It also keeps you on the right side of the rules that protect the scheme water network.

Don't wait on a leak

Even a small leak wastes water and money every single day, and a burst pipe can cause thousands in damage in a single afternoon. The sooner it's fixed, the less it costs. If you've got water where it shouldn't be, our 24/7 emergency plumbers are ready to respond.

Preventing future pipe failures

While some pipe bursts come out of nowhere, plenty can be headed off. If your home has old galvanised steel pipes, they corrode from the inside out and will eventually fail, so planning a repipe before they burst saves you the flood and the damage. Keeping your water pressure within a sensible range protects joints and fittings across the whole house, and if your pressure seems unusually high, a pressure limiting valve is a cheap fix that spares your pipes years of strain. Where tree roots are the culprit, dealing with the roots and repairing the affected line stops the same section failing again.

It's also worth knowing the age and material of your pipework, especially if you're buying an older home in suburbs like Riverton, Willetton or Gosnells. A quick inspection can flag pipes that are living on borrowed time, letting you budget for replacement on your terms rather than after a 2am burst. We're happy to assess your plumbing and give you a straight opinion on what, if anything, needs attention.
