Our Comprehensive Leak Detection Services
At GPS Plumbing, we use state-of-the-art tools and proven techniques to find and fix any type of leak.
Water Leaks
Hidden leaks from pipes, fixtures, and fittings can cause serious water damage and mould. Our experts use advanced technology to quickly trace the source of any water leak, preventing further damage to your property.
Gas Leaks
Gas leaks are extremely dangerous and pose a serious safety risk. Our licensed technicians perform thorough inspections to safely detect and repair any gas leak. With our expertise in gas fitting, we treat every gas leak with the urgency it requires.
Roof Leaks
Leaks from worn tiles, damaged flashing, or blocked gutters can damage your ceilings and walls. We accurately diagnose the source of the leak and recommend the best repair solution to prevent costly interior damage.
Subsurface Leaks
Underground leaks are difficult to find and can cause major foundation or landscape damage. We use specialised equipment to locate leaks in buried pipes with minimal disturbance to your property, saving you time and money.
Bathroom & Kitchen Leak Detection
Leaks in wet areas like bathrooms and kitchens often go unnoticed until significant damage is done. We pinpoint hidden leaks behind tiles and cabinets, a crucial step in any bathroom renovation to prevent future issues.
Pool Leaks
A leaking pool wastes thousands of litres of water and drives up your bills. Our experts precisely locate leaks in your pool’s structure or plumbing, so you can stop the water loss and get back to enjoying your pool.
Find Leaks Fast with Advanced Technology
We use the industry’s most sophisticated tools to find leaks accurately without damaging your property.
- Thermal Imaging: Our infrared cameras detect temperature differences in walls and floors, revealing hidden moisture from leaks that are invisible to the naked eye.
- Acoustic Sensors: Highly sensitive listening devices allow us to hear the distinct sound of water escaping from pipes, even deep underground.
- CCTV Inspection Cameras: We use tiny, waterproof cameras to see inside your pipes, allowing us to identify cracks, blockages, or breaks without any guesswork.
- Electronic Leak Detection: This equipment detects the sound frequency of pressurised water escaping from buried pipes, pinpointing the exact location of the leak.
This technology allows us to work efficiently, saving you time, money, and the stress of unnecessary property damage.
Warning Signs of a Hidden Leak
As a homeowner, it’s important to know the signs of a potential leak. Call us if you notice any of the following:
- Sudden Spike in Water Bills: If your bill is unexpectedly high but your water usage hasn’t changed, you likely have a leak.
- Damp or Discoloured Spots: Check for damp patches, water stains, or peeling paint on walls, ceilings, or floors.
- Mould or Musty Smells: A persistent musty odour or visible mould growth often indicates a hidden moisture source from a leak.
- Sound of Running Water: If you can hear water running when all taps and appliances are off, it’s a clear sign of a leak.
