WATER LEAK DETECTION

Signs of water leaking and time to investigate:

  • Abnormally high water bill
  • Unusual wet area
  • Sunken ground
  • Lawn green spot
  • Mould or mildew wall
  • Water meter keeps spinning
  • Loss of pressure
  • Change in surface temperature
These are just a few helpful tips. For FREE ADVICE call and speak to our friendly staff

How do you find a water leak underground?

We find underground water leaks without digging up your property. First we check the water meter to confirm and measure the water loss, then inspect taps and fixtures. Next we scan the area with ground penetrating radar (GPR) and cable locators to map where the water pipes run. Once the pipe route is known, acoustic leak detectors listen for the sound of water escaping, and the signal gets louder as we get closer to the leak point. For very small leaks, tracer gas can be used. We then mark the leak position on the ground so repairs can be made in the right spot.

How do I know if I have an underground water leak?

Common signs of an underground water leak are a sudden jump in your water bill, the water meter still moving when all taps are turned off, lower water pressure, wet or soggy areas that never dry, sunken ground or paving, and a patch of lawn or garden that grows greener than the rest. Inside, look for bubbling paint, mould or mildew on walls. Pets can give a clue too: a dog that suddenly prefers one spot may have found a cool area over a cold water leak in summer, or a warm area over a hot water pipe leak in winter. If you notice any of these signs, check your water meter first, then call us to locate the leak.

How do I check my water meter for a leak?

Turn off every tap and water-using appliance on the property, including reticulation, the dishwasher and the washing machine. Then look at your water meter, usually near the front boundary, and write down the reading. Many meters also have a small red dial that spins with even a tiny flow. Wait 30 to 60 minutes without using any water and check again. If the reading has changed or the small dial is still moving, water is escaping somewhere between the meter and your taps. That is often an underground leak, and the time to call us. See our simple water leak test for more tips.

What equipment is used to detect underground water leaks?

We use a combination of tools, chosen for each job. Ground penetrating radar (GPR) and cable locators map where the water pipes run. Electronic acoustic leak detectors with ground microphones listen for the sound of water escaping under pressure. Tracer gas is injected into the pipe to find very small leaks that are too quiet to hear, and thermal imaging cameras can show temperature changes caused by leaking hot or cold water. Our acoustic equipment is portable enough to travel as air baggage, which is how we carried out leak detection for Chevron on Barrow Island. Read more about our leak detection equipment.

How much does water leak detection cost in Perth?

The cost depends on the size of the property, how far the pipes run, how easy the area is to access, and whether the site is in Perth metro or regional WA. A single leak on a house block usually takes less time than a large commercial or industrial site with long pipe runs. Because finding the leak accurately the first time avoids unnecessary digging and repeat call-outs, it often saves money on repairs and water bills.

Can you find a water leak under a concrete slab or driveway?

Yes. Water pipes often run under concrete slabs, driveways and paving, so we use concrete scanning with ground penetrating radar (GPR) to trace the pipe route without breaking anything. Acoustic leak detectors can then pick up the sound of escaping water through the concrete and pinpoint the leak, so only a small area needs to be opened for the repair. We regularly locate water pipes under house and garage slabs, and under driveways, paving and paths.

Can you find leaks in reticulation pipes?

Yes. Reticulation leaks are common in Perth, especially on older systems where the pipes and solenoid boxes have been buried under lawn, garden beds or paving over the years. Signs include soggy patches that never dry, a zone with weak sprinklers, or the water meter moving when the reticulation is switched off. We trace the solenoid wires with a cable locator, map the poly and PVC pipes with ground penetrating radar (GPR), and use acoustic leak detection on the pressurised main line to pinpoint the leak. Learn more about locating reticulation piping and solenoids.

Do you do commercial and industrial leak detection?

Yes. Commercial and industrial sites usually have longer pipe runs, water mains and fire services, and leaks need to be found without disrupting the business. We locate leaks on water mains, fire mains and hose reel lines, including pipework that fails a pressure test on new construction. On a commercial strata complex in Landsdale, we traced the fire main with GPR and used tracer gas to find a loose end cap that was losing pressure. We have also located leaks for Chevron at the Barrow Island LNG plant. See our commercial leak detection case study.

Can I find an underground water leak myself with an app or detector?

There is no mobile phone app that can reliably find a leak in an underground pipe. Phone microphones and apps are not sensitive enough to hear water escaping through soil or concrete. You can check for a leak yourself by turning off all taps and watching the water meter, but pinpointing where the leak is needs professional equipment such as ground microphones, electronic acoustic detectors and tracer gas, along with experience in interpreting the results. Professional acoustic leak detectors are expensive to buy and take practice to use well, so for most homeowners it is quicker and cheaper to have the leak located once, accurately, before digging.

I found Westscan to be easy to deal with. Tony was very helpful in setting up our booking, being able to book us in 2 days from the date we accepted their quote. Jeff was extremely punctual and was very pleasant to work with in attempting to locate our water pipes under our garage slab. I would have no hesitation in recommending Westscan to any business or individual who needs to avail themselves of the services they offer.
