How is a Leak Detected?

• Visual Inspection: For obvious leaks, such as water pooling or damp patches, a professional will start with a visual inspection to identify potential sources.
• Thermal Imaging: This technology detects temperature differences behind walls, floors, and ceilings, helping locate hidden leaks without causing damage.
• Acoustic Detection: Using specialised equipment, professionals listen for the sound of water escaping from pipes, especially useful for underground or concealed leaks.
• Moisture Metres: These devices measure the moisture content in walls and floors to help identify the source of a leak.
• Tracer Gas Detection: Tracer gas is pumped into the pipe system and detected at the leak location, even for small leaks that are difficult to locate.
• Plumbing Camera Inspection: A camera is inserted into the pipe to visually inspect for blockages or leaks, often used for underground or in-wall pipes.

How Long Does it Typically Take to Detect a Leak?

• Visual inspection: 30 minutes to 1 hour
• Thermal imaging: 1-2 hours depending on the area being scanned
• Acoustic leak detection: 2-4 hours, especially for underground or hard-to-reach pipes
• Moisture metre reading: 30 minutes to 1 hour
• Tracer gas detection: 1-2 hours
• Plumbing camera inspection: 1-3 hours depending on the length of the pipes and ease of access

DIY - Can You Detect a Leak Yourself?

While some leaks are easy to spot, such as dripping faucets or visible water damage, hidden leaks require specialised equipment to locate without causing damage. Homeowners can try some simple methods to check for leaks:

• Check for Damp Patches: Look for damp spots on walls, ceilings, or floors, especially near plumbing fixtures.
• Water Meter Test: Turn off all water in the house and check the metre. If it moves, there’s likely a hidden leak.
• Food Dye Test: Add food dye to the toilet tank and see if it seeps into the bowl without flushing. If it does, you have a leak.

However, for underground leaks or those behind walls, it’s best to contact a professional leak detection service to avoid unnecessary damage to your home.

When Should You Get Professional Help?

If you notice unexplained increases in your water bill, damp patches, mould growth, or water pooling where it shouldn’t be, it’s time to call in a professional leak detection service. DIY methods might identify obvious leaks, but hidden or complex leaks require the expertise and equipment of professionals. Prompt detection can save you money on repairs by addressing leaks before they cause extensive damage.

How to Save Money on Leak Detection Services?

• Compare quotes from different leak detection companies.
• Act quickly: Addressing a leak early prevents more expensive repairs.
• Prepare the area: Clear access points to pipes or plumbing to save the professional time.
• Combine services: If you need plumbing repairs or maintenance, see if the plumber can do the leak detection at the same time to save on call-out fees.

Frequently Asked Questions About Leak Detection Services

Q: How do I know if I have a hidden leak?
A: Signs of a hidden leak include unexplained increases in your water bill, damp spots, mould growth, and musty odours. If you hear the sound of running water when no taps are open, this may also indicate a hidden leak.

Q: Is thermal imaging reliable for detecting leaks?
A: Yes, thermal imaging is one of the most reliable, non-invasive methods for detecting leaks. It helps locate hidden leaks behind walls and under floors by showing temperature differences caused by moisture.

Q: Can leak detection damage my property?
A: Professional leak detection methods, such as thermal imaging and acoustic detectors, are non-invasive and won’t damage your property. However, if the leak is severe and behind walls or underground, some minimal work may be needed to access the pipes.

Q: How often should I get leak detection services?
A: Leak detection is typically only needed when you suspect a leak. However, if you have an older home or a history of plumbing issues, regular checks can help prevent major problems.

Q: How accurate is acoustic leak detection?
A: Acoustic leak detection is highly accurate for underground or concealed leaks. It uses sound waves to detect water escaping from pipes and is especially useful for pinpointing leaks without causing damage.

Q: Will my insurance cover the cost of leak detection?
A: Many home insurance policies cover leak detection and the resulting repairs, but it’s essential to check your specific policy. Some may cover only the repair of the leak, while others may include the detection process.

Q: What causes water pipes to leak?
A: Leaks in water pipes can be caused by corrosion, poor installation, excessive water pressure, freezing temperatures, or wear and tear over time. Tree roots can also cause underground pipes to crack, leading to leaks.

Q: How can I prevent leaks in my home?
A: Regular maintenance of plumbing fixtures, checking for signs of leaks, and ensuring proper pipe insulation can help prevent leaks. It’s also important to monitor your water bill for unusual increases, which could indicate a hidden leak.

Q: Can a small leak become a big problem?
A: Yes, even a small leak can lead to bigger issues if left unchecked. Water damage can spread, causing mould growth, structural damage, and increased water bills. Small leaks should be repaired as soon as they are detected to prevent costly repairs down the line.

Q: How much water can a small leak waste?
A: A small drip from a leaky faucet can waste up to 20 litres of water a day, and a constantly running toilet can waste hundreds of litres daily. Over time, even small leaks can lead to significant water wastage and higher utility bills.

Q: Will I need to turn off the water supply during leak detection?
A: In some cases, especially if a pipe leak is suspected, you may need to turn off the water supply temporarily while the professional performs the inspection. The plumber will let you know when this is necessary, and it’s usually for a short duration.
