Local Leak Detection Solutions

At Champion Plumbing & Drains, we provide expert water leak detection for homes across Sydney’s Inner West. If you suspect a hidden water leak, notice an increase in your water bills, or see damp patches growing, our licensed plumbers use advanced leak detection equipment to locate the exact source without disrupting your property. With years of leak detection experience, we have the skills to service older properties in Ashfield and Newtown, as well as modern homes in Rozelle and Drummoyne, finding underground water leaks efficiently and often repairing them that same day.

What is Leak Detection?

Leak detection involves using advanced technology to locate water leaks in your plumbing system without tearing up floors, walls, or gardens. 

 

Our licensed plumbers use acoustic leak detection devices that listen for the sound of water escaping from your pipes and thermal imaging to detect temperature changes caused by hidden water leaks. This approach saves time, reduces the cost or repairs, and protects your property from unnecessary damage because we find the exact location before any digging starts, compared to traditional methods that require extensive excavation.

Signs You Have a Hidden Water Leak

Watch for these common warning signs in your inner west property:

Icon of a plumbing bill
Unexplained increases in your water bill
Icon of two pools of water
Damp patches on walls, ceilings, or floors
Icon of an ear
Sound of running water when taps are off
Icon of a nose
Bad smells or mould growth
Icon of grass blades
Soft spots in your lawn or constant wet patches
Icon of a cracked tile
Cracks in your foundation or walls

Ignoring a hidden water leak can lead to structural damage, mould growth, and water bills costing you thousands. Our leak detection specialists locate the problem quickly so we can start repairs straight away. 

Our Leak Detection Services

Acoustic Leak Detection

We use acoustic leak detection technology to pinpoint water leaks in underground pipes, walls, and irrigation systems without digging. Unlike visual inspections, this method detects hidden leaks through concrete, driveways, and landscaping.

Thermal Imaging Detection

We use thermal imaging to detect hidden water leaks behind walls, under floors, and beneath concrete, making it ideal for older Sydney homes.

Underground Water Leak Location

Our underground water leak detection service uses a combination of acoustic equipment, pressure testing, and tracer gas technology to find leaks in water mains and service lines buried under your property.

In most cases, yes. Hidden water leaks can waste hundreds of litres of water per day, significantly increasing your water bills. A typical slow leak can waste 200 to 400 litres daily, sometimes adding $30 to $60 per month to your bill. Once we find and repair your leak, your water usage will go back to normal, and you should see a change in your next bill. 

Book Now

A quick assessment you can do at home is to check your water meter before you go to bed and again in the morning without using any water. If the meter reading has changed, there’s a good chance you have a leak. Other signs we see include increased water bills, damp patches, or the sound of running water when all taps are off.
