Hidden water leaks Perth are one of the most likely culprits when a Water Corporation bill suddenly comes in far higher than usual. Opening a bill like that is stressful, especially if your household habits have not changed. In Perth, where most water pipes run underground, through concrete slabs or inside walls, a hidden water leak can run for weeks or months before you notice anything other than the cost.
Water leaks have also been in the news across WA this year, with reports of significant losses from ageing infrastructure around the state. It is a good reminder that leaks are not just a household problem, and that every litre wasted in our drying climate matters. The good news is that hidden water leaks Perth homeowners face on their own property can usually be found quickly and fixed properly, and you may even be able to recover part of the cost.
Common Signs of a Hidden Water Leak
Not every leak announces itself with a puddle. Keep an eye out for these warning signs:
- An unexplained jump in your water bill. This is often the first and only clue.
- Damp patches or bubbling paint on walls, ceilings or skirting boards.
- Lifting floor tiles, cracked grout or swollen timber floors, which can point to a leak under a slab.
- Musty smells or mould in cupboards or wet areas.
- Unusually green or soggy patches in the lawn or garden, even in dry weather.
- The sound of running water when every tap in the house is turned off.
- Cracks in paving or walls caused by water undermining the ground below.
How to Check for a Leak Yourself
Before calling a plumber, you can do a simple meter test:
- Turn off every tap, appliance and irrigation system on the property.
- Locate your hidden water leaks Perth meter, usually near the front boundary, and write down the reading (or take a photo).
- Avoid using any water for at least 30 minutes, or ideally a couple of hours.
- Check the meter again. If the numbers have moved, water is escaping somewhere.
You can also add a few drops of food colouring to your toilet cistern. If colour appears in the bowl without flushing, the cistern is leaking, which is a common and easily fixed source of wasted hidden water leaks Perth.
If the meter test confirms a leak but you cannot see where it is coming from, it is time for professional leak detection.
Can I Get Money Back on a High Water Bill?
Water Corporation offers a leaks allowance that may help eligible customers recover part of the cost of water lost through a hidden leak. Based on the information currently published, the key points are:
- The leak generally needs to have been hidden, not visible or readily detectable.
- Repairs to internal and underground pipes must be carried out by a licensed plumber, and you will usually need documentation of the repair.
- The allowance covers part of the water lost, not the cost of the repair work itself.
- There are time limits for completing the repair and lodging your application, and each claim is assessed individually.
Rules and thresholds can change, so check the current criteria on the Water Corporation website and keep copies of your bills and your plumber’s invoice. Acting quickly is important: the sooner the leak is repaired, the less water you lose and the stronger your application is likely to be.
Don’t Forget About Gas Leaks
Hidden water leaks Perth cost money, but gas leaks can put your family at risk. Many Perth homes still have natural gas or LPG connected for cooking, heating or hot water, and ageing gas pipes and fittings can deteriorate over time.
Signs of a possible gas leak include:
- A “rotten egg” smell around appliances, the gas meter or outside the home.
- A hissing or whistling sound near gas lines or appliances.
- Dead or dying plants above where a gas line runs.
- Higher than expected gas bills.
- Pilot lights that keep going out, or burner flames that are yellow or orange rather than blue.
If you suspect a gas leak, do not use light switches, phones or anything that could cause a spark near the area. Turn off the gas at the meter if it is safe to do so, open doors and windows, leave the property and call for help from a safe distance. In an emergency, call 000. Gas work in WA must only be carried out by a licensed gas fitter; never attempt to fix a gas leak yourself.
How Professional Leak Detection Works
Modern leak detection is non-invasive. Rather than digging up your yard or breaking open walls on a hunch, a specialist uses tools such as:
- Acoustic listening equipment that picks up the sound of escaping water underground or under slabs.
- Thermal imaging cameras that reveal temperature differences caused by leaking hot or cold water.
- Pressure testing to isolate which section of pipework is losing water or gas.
- Tracer gas to pinpoint very small or hard-to-reach leaks.
The aim is to find the exact location so only a small, targeted area needs to be opened for the repair.
Why One Company for Detection and Repair Matters
Here is something many homeowners only discover after the fact: a lot of leak detection businesses only find leaks. Once they have marked the spot, you need to book a separate plumber to come back and carry out the repair. That means two call-outs, two bills, more time without water and more days of hidden water leaks Perth flowing down the drain.
Plumbdog does both. Our team detects the leak and repairs it, usually in the same visit, so you are not left waiting for a second contractor. And because Plumbdog are licensed gas plumbers, we detect and repair both water leaks and gas leaks. Whether it is a burst pipe under the slab, a leaking irrigation line or a suspected gas leak at your meter, you deal with one team from start to finish.
Practical Tips to Prevent Leaks
- Read your water meter every few months so you know what “normal” looks like.
- Check under sinks, behind toilets and around the hot water system regularly.
- Have older homes, especially those with original copper or galvanised pipes, inspected periodically.
- Know where your water and gas shut-off valves are, and make sure they turn freely.
Stop Paying for Water You Don’t Use
A hidden leak will not fix itself, and every day it runs adds to your bill and the risk of damage to your home. If your water bill has jumped, your meter is moving when everything is off, or you can smell gas, get it checked by licensed professionals who can find the problem and fix it in one go.
