THE DANGERS OF HIDDEN WATER LEAKS

A hidden water leak can cause significant and costly damage to your home if left undetected. Beyond increasing your water bills, ongoing moisture can weaken your property’s structural integrity, rot timber framing, damage walls, and cause floors to warp.

The damp conditions created by hidden leaks also encourage mould growth, which can affect your family’s health and indoor air quality. In addition, water leaking near electrical wiring can create serious safety hazards.

That’s why it’s important to contact a trusted water leak detection plumber in Wollongong as soon as you suspect a leak. Acting early helps protect your home, prevent extensive damage, and avoid expensive repairs.

How We Fix and Prevent Water Leaks

Our experienced water leak detection plumbers in Wollongong respond promptly to identify and repair hidden water leaks using advanced, non-invasive leak detection technology. This allows us to accurately locate the source of the leak without unnecessary excavation or damage to your property.

Once the leak has been identified, we isolate the affected water supply and complete reliable repairs on-site whenever possible. Before finishing the job, we thoroughly test your plumbing system to ensure the leak has been fully resolved.

To help prevent future water leaks, our team can also recommend preventative solutions such as pressure limiting valves, routine plumbing inspections, and ongoing maintenance.

At Network Plumbing, we don’t just repair leaks – we provide long-term solutions to protect your home and plumbing system.

Signs You Need a Water Leak Detection Plumber in Wollongong

Not all water leaks are easy to spot. Many occur behind walls, beneath concrete slabs, under floors, or underground, remaining hidden for weeks or even months. Knowing the warning signs can help you detect leaks early and minimise costly damage.

If you notice any of the following, it’s time to contact a professional water leak detection plumber in Wollongong:

  • Unexpectedly high water bills
  • Damp patches or wall discolouration
  • Musty or mouldy odours
  • Warped flooring or damaged surfaces
  • Hissing or dripping sounds inside walls
  • Visible mould or mildew growth
  • A constantly spinning water meter
  • Reduced water pressure
  • Cracks in walls or foundations
  • Warm spots on tiled or concrete floors
  • A continuously running hot water system


Early leak detection can save you thousands in repair costs while protecting your home from long-term water damage.

common leak locations in wollongong homes

1. Bathroom Leaks

This is the most common area for leaks, often originating from shower waterproofing failures, leaking shower taps, cracked tiles or grout, or failed seals around the bath.

2. Leaking Toilets

A constantly running or leaking toilet can waste a huge amount of water. Leaks can occur at the cistern inlet or outlet valve, the connection pipe, or the wax seal at the base.

3. Hot and Cold Supply Lines

The pressurised pipes that deliver water to your taps and fixtures can develop pinhole leaks or splits due to age, corrosion, or high water pressure.

4. Underground and Slab Leaks

Pipes located under concrete slabs or in the ground can corrode or crack over time due to ground movement or soil conditions. These are notoriously difficult to detect without specialised equipment.

5. Roof, Gutter, and Flashing Leaks

Damaged roof tiles, rusted gutters, or failed flashing around vents and chimneys can allow rainwater to enter your roof space, leading to ceiling stains and structural damage.

6. Leaks From Appliances

Flexible hoses connecting dishwashers and washing machines can burst, and internal components can fail, causing major flooding and water damage.

7. Irrigation and Garden Tap

Underground sprinkler systems and outdoor taps are susceptible to damage from root intrusion, freezing, or accidental impact.

24/7 EMERGENCY WATER LEAK DETECTION SERVICES WOLLONONG

When a plumbing emergency strikes, every minute counts. Our experienced water leak detection plumbers in Wollongong are available 24/7 to quickly locate and repair hidden water leaks before they cause further damage to your property.

Our fully equipped service vehicles carry the latest leak detection equipment and plumbing tools, allowing us to diagnose and repair a wide range of emergencies, including hidden water leaks, burst pipes, blocked drains, hot water system failures, and gas fitting issues.

Whether it’s a minor leak or a major plumbing emergency, you can rely on Network Plumbing for fast, professional service and lasting repairs throughout Wollongong.

WHAT SAFE STEPS CAN I TAKE IN A PLUMBING EMERGENCY?

1. Burst Pipe

If you are experiencing a burst pipe, locating your water supply and turning it off until our emergency service arrives may just save you unforeseen costs. Limiting the plumbing service by turning off the water mains is usually the safest play. For emergency burst pipe repair, our plumbers are available 24/7 to assist you.

2. Blocked Drain

If your emergency involves blocked drains, locating and turning off your water mains might be advisable. If you’re experiencing backflow in your plumbing service, turning off your water will inhibit any flow of water from your taps or any toilets that might be flushed while our blocked drain emergency plumber Sydney are on the way.

3. No Hot Water

If it’s an emergency hot water situation and you no longer have any hot water, waiting for our emergency plumbers to arrive is probably your only option. 

If your hot water heater has sprung a leak, be careful of the hot water that may be escaping from the hot water tank. Use towels and buckets to collect the water leaks where possible but remember you’re dealing with hot water, safety above all else. Our local 24 hour plumber near you will assess the situation and make sure everyone is safe before proceeding to fix your plumbing issues. Rest assured, you’re in safe hands, we deliver great service at every turn.

Hot water systems that require a gas connection should be treated with care. In some cases, turning off your gas supply in an emergency may be appropriate. When you contact our emergency plumber Sydney, they will advise you on the best action forward.

Frequently asked questions

Do you have more burning questions about leaking taps, a blocked toilet or your plumbing system? Here are some plumbing solutions.

Our step-by-step leak detection and repair process

We follow a systematic and professional process to ensure your leak is found and fixed with minimal disruption.

  1. Initial Consultation: When you call, we listen carefully to your concerns and ask questions to understand the problem. We may offer immediate advice, such as how to shut off your water.
  2. Site Assessment: Our plumber arrives on time and conducts a thorough visual inspection of your property, looking for the common signs of a leak.
  3. Non-Invasive Testing: Using our advanced diagnostic tools, we begin the detection process, starting with the least invasive methods to narrow down the location.
  4. Pinpoint Location: We methodically trace the source until we have pinpointed the exact location of the leak with the highest possible accuracy.
  5. Provide Options and a Quote: Once the leak is found, we explain the problem clearly, outline your repair options, and provide a fixed, upfront price for the work.
  6. Immediate Make-Safe or Repair: With your approval, we can often perform an immediate repair. If the job is complex, we will perform a “make-safe” to stop the leak and prevent further damage before scheduling the full repair.
  7. Re-Test and Verify: After the repair is complete, we re-pressurise and test the system to ensure the leak is 100% fixed.
  8. Clean Up: We treat your home with respect and always clean up our work area thoroughly.
  9. Prevention Advice: We provide tips on how to prevent future leaks and monitor your plumbing system.
  10. Detailed Reporting: If required, we can provide a comprehensive report with photos for your insurance company or strata manager.
What your water meter is telling you?

Your water meter is designed to detect any flow, no matter how small. When you see movement on the meter but know you are not using any water, it is a direct signal that water is escaping somewhere. Different types of movement can point to different problems.

  • Constant, steady movement: If your meter’s dial is spinning continuously, you likely have a significant, active leak. This could be a burst pipe under your lawn in Figtree or a major fault in a fixture. This situation requires immediate professional attention to prevent major water loss and property damage.
  • Slow or occasional movement: A dial that creeps forward slowly, or a number that ticks over every few minutes, indicates a small but persistent leak. While it may seem minor, a slow drip from a tap or a leaky toilet in your Corrimal home can waste thousands of litres of water over a year, adding up to huge bills.
  • Movement only at night: If you notice your meter ticking over during the quiet hours, it often points to a concealed issue. Common causes include a toilet cistern that is quietly refilling itself or a temperature and pressure relief valve on a hot water system that is failing.
  • A quick spin after a toilet flush: If you notice the meter’s dial moves a little, long after the toilet cistern has refilled, it suggests the cistern’s outlet valve is not sealing properly, allowing water to constantly seep into the bowl.

Ignoring these signs can lead to warped floors, electrical hazards, and expensive structural repairs.

How does your water help detect a water leak?

Your water meter is your home’s most reliable early warning system for hidden water leaks. While a surprise high water bill is a clear sign of trouble, understanding what your meter is telling you can help you catch a problem early. If your meter shows water is flowing when all taps and appliances are off, you almost certainly leak in your property.

How much does leak detection cost?

The cost involves a service fee for the detection process. The total price depends on the complexity and time required to pinpoint the leak. We provide a transparent, upfront price for both detection and repair.

How long does it take to find a leak?

Most common leaks can be found within 1-2 hours. However, very complex or multiple leaks can take longer. Our goal is to be as efficient as possible without sacrificing accuracy.

Is your leak detection process destructive?

Our methods are non-invasive. We aim to find the leak with minimal disruption. In most cases, we can locate the leak without any cutting or digging. If access is required for a repair, it will be minimal and targeted.

How do I turn off my water in an emergency?

Your main water shut-off valve is usually located at the front of your property, near the water meter. Turn the handle or tap clockwise until it stops.

What if the leak is under a concrete slab?

We use our specialised acoustic and tracer gas equipment to pinpoint the exact location. Repair options can then be discussed, which may include a direct repair or re-routing the pipe to bypass the damaged section.

What should I do while waiting for the plumber to arrive?

If possible, turn off your main water supply to prevent further damage. If the leak is near electrical outlets, turn off the power to that area at your switchboard. Move any furniture or valuables away from the affected area.

What are some leak detection methods?

To find hidden leaks without causing unnecessary damage to your property, we use a combination of advanced diagnostic tools and proven techniques. Our plumbers are highly trained in using this specialised equipment to pinpoint the exact location of the problem.

Acoustic Leak Detection

This is one of the most effective methods for finding leaks in pressurised pipes. We use highly sensitive ground microphones and listening devices to “hear” the distinct sound vibrations that escaping water creates. By tracing the sound to its loudest point, our plumbers can accurately locate the leak, even if it is buried deep underground or within a concrete slab.

Thermal Imaging Cameras

Our thermal imaging cameras detect minute temperature differences on surfaces. When a hot water pipe is leaking, it will create a warm plume in the surrounding area, which shows up clearly on the camera’s display. This technology is invaluable for finding leaks in hot water lines concealed within walls, floors, and ceilings without any invasive cutting. It can also identify cold spots caused by moisture from cold water leaks.

Tracer Gas Testing

For particularly elusive leaks or situations where acoustic and thermal methods are inconclusive, we use tracer gas. A safe, non-toxic gas mixture (typically hydrogen and nitrogen) is introduced into the drained pipe system. The gas is lighter than air and will escape at the leak point, rising to the surface. We then use a sensitive gas “sniffer” or detector to identify the precise location where the gas is emerging.

Moisture Meters

These handheld devices allow us to measure the moisture content of various building materials, such as drywall, timber, and concrete. By taking readings at different points, we can map the extent of water saturation and trace the moisture back to its source, confirming the presence of a leak and identifying the affected area.

Pipe and Cable Locators

Before we begin any excavation, it is essential to know exactly where your pipes and other utilities are located. We use electronic locators that transmit a signal along a pipe, allowing us to trace its path and depth accurately. This prevents accidental damage to other services and ensures we dig in the correct spot.

Pressure Testing

To confirm if a specific section of pipework is leaking, we can isolate it and subject it to a pressure test. We use a pump to fill the pipe with water or air to a designated pressure. If the pressure drops over a set period, it confirms a leak exists within that isolated line, helping us narrow down the search area significantly.

CCTV Drain Cameras

For leaks suspected in drainage or sewer lines, we use high-resolution CCTV drain cameras. A flexible rod with a camera on its tip is fed into the pipe, sending a live video feed back to our monitor. This allows us to visually inspect the entire length of the pipe for cracks, breaks, root intrusion, or separated joints that could be causing leaks.

Dye Testing

A simple yet effective method, dye testing involves introducing a brightly coloured, non-staining dye into the plumbing system, such as a toilet or drain. If the coloured water appears in an area where it should not be (like the base of the toilet or a downstream manhole), it confirms the path of the leak.

Isolation and Step Testing

This methodical process involves systematically shutting off different sections of your plumbing system to isolate the leak. By monitoring the water meter after each step, we can determine which branch line or fixture is responsible for the water loss, greatly reducing the search area.
