Common Signs of Water Leaks

Recognising the signs of water leaks early can save you time, money, and stress. Here are some common signs to watch out for:


Damp or Discoloured Walls and Ceilings

Water leaks often result in unsightly stains or discolouration on your walls or ceilings. These marks range from small, yellowish spots to larger, spreading patches.

Peeling Paint or Wallpaper

Moisture can cause paint or wallpaper to peel away from the surface. It could indicate hidden water leaks if you notice bubbling or peeling in your walls.

Musty Odours

A persistent musty or earthy smell in your home can indicate hidden moisture. This odour is often associated with mould growth, which thrives in damp environments.

Unexplained Increase in Water Bills

If your water bills suddenly spike without any apparent increase in usage, it might be due to a hidden water leak. Keep an eye on your water bills and investigate any unexplained increases.

Low Water Pressure

Decreased water pressure in your taps and showers can indicate a leak in your plumbing system. Leaks can reduce the amount of water reaching your fixtures.

Constantly Running the Water Meter

If your water meter continues to run even when you’re not using water in your home, it could indicate a leak somewhere in your plumbing.

Puddles or Pooling Water

Visible water puddles or pooling in areas like your basement, crawl space, or yard indicate a leak. Pay attention to these signs, as they can lead to more significant damage over time.

Warped or Buckled Flooring

Wooden or laminate flooring can warp or buckle when exposed to excess moisture. If your floors suddenly become uneven or start to warp, investigate for potential leaks.

Sounds of Dripping or Running Water

If you hear the sound of water running or dripping when no faucets are turned on, it indicates a leak. Investigate the source immediately.

Taking action promptly is crucial if you notice these signs in your home. Ignoring water leaks can lead to more extensive damage and costly repairs down the line. Contact a professional plumber or contractor to assess and address the issue before it worsens.

DIY Leak Detection Methods

Discovering a water leak in your home early can save you from costly repairs and water damage. Fortunately, you can employ several DIY leak detection methods to identify potential issues before they become significant problems. Here are some effective techniques to help you spot leaks on your own:


Visual Inspection

Start with a thorough visual examination of your home. Look for any common signs of water leaks, such as damp spots, discolouration, or peeling paint on walls and ceilings.

Check Your Water Metre

Turn off all water sources in your home and monitor your water meter for a period of time, typically a few hours. If the meter reading changes during this time, it strongly indicates a hidden leak.

Toilet Dye Test

Place a few drops of food colouring or a dye tablet in the toilet tank to check for toilet leaks. Wait for about 15-20 minutes without flushing. If the water in the bowl changes colour, it indicates a leak from the tank to the bowl.

Listen for Unusual Sounds

Pay attention to any unusual sounds, such as dripping or running water, when no fixtures are used. These sounds can lead you to the source of a leak.

Feel for Moisture

Run your hands along pipes, hoses, and fixtures under sinks, behind appliances, and around water heaters. There may be a leak if you feel moisture or detect any dampness.

Use a Water Leak Detector

Invest in a water leak detection device or sensor. These gadgets can be placed in areas prone to leaks, like basements or near water heaters, and will alert you if they detect excess moisture.

Inspect Outdoor Areas

Check your outdoor faucets, hoses, and irrigation systems for any visible leaks or pooling water. A soggy yard or garden could be a sign of an underground leak.

Monitor Your Water Bill

Keep an eye on your monthly water bills. A sudden and unexplained increase in usage can indicate a hidden leak.

Check for Mould and Mildew

Regularly inspect areas prone to moisture, such as bathrooms, basements, and crawl spaces, for any signs of mould or mildew growth. These fungi thrive in damp environments.

DIY Pipe Pressure Test

If you suspect a pipe leak, you can perform a simple pressure test using a pressure gauge. Instructions can be found online or obtained from a hardware store.

While these DIY methods can help you identify potential leaks, it’s essential to remember that some leaks may be challenging to detect without professional equipment. Suppose you suspect a significant or hidden leak or are uncertain about its source.

In that case, it’s wise to consult a plumber or a professional leak detection service for a comprehensive assessment and timely repairs.

When To Call A Professional


Knowing when to call a professional for plumbing issues is crucial to prevent further damage and ensure your safety. You should contact a licensed plumber if you’ve detected signs of a water leak, such as extensive moisture, a sudden drop in water pressure, or unexplained increases in your water bills.

Additionally, professional expertise is essential if you’re unsure about the source or extent of a leak or if you suspect hidden plumbing problems. Fixing complex plumbing issues without the right knowledge and tools can lead to costly mistakes.

Feel free to reach out to a qualified plumber who can accurately diagnose the problem and provide effective solutions, saving you time, money, and potential headaches down the line.

Preventing Water Damage

Preventing water damage requires proactive maintenance and inspection of your home. Stay on top of tasks like cleaning gutters, checking appliances for leaks, and sealing windows and doors. Fix any drips, leaks or malfunctions immediately before they worsen. Ensure proper insulation to avoid frozen, burst pipes. Install safeguards like sump pumps if you live in a flood-prone area.

Routine maintenance helps avoid water damage down the line. Inspect your roof for damaged shingles that need replacing. Check that the grading around your home slopes away from the foundation, allowing proper drainage. Replace any washing machine hoses showing wear and tear. Catching minor issues promptly is key to prevention.

When leaving your home for extended periods, take preventative measures by turning off the main water supply. This minimises potential leaks while you’re away. Upon returning, examine pipes and appliances for any new drips or other issues, such as burst pipes. Stay vigilant in watching for leaks, sealing entry points, and maintaining your home to avoid costly water damage.

Temporary Leak Fixes

When you encounter a water leak in your home, it’s crucial to address it promptly to prevent further damage while waiting for professional repairs. Here are some temporary leak fixes you can implement:


Stop The Flow Of Water

The first step when encountering a water leak is to locate the source and turn off the valve or main water supply. This is crucial to halt further water damage.

Seal The Leak – Quickly!

Products like epoxy putty and specialised plumbing tape can provide a temporary seal for small leaks in pipes or plumbing joints. Wrapping hoses with rubber tape or installing a rubber patch can also temporarily stop leaks. Pipe repair clamps placed around the leak or tightening loose fittings carefully are other options.

Contain The Water Or Leakage

It’s important also to contain any escaping water to prevent spreading. Place buckets or towels under leaks to collect the water, emptying frequently. In an emergency, cloth and duct tape can help contain a leak. This buys time until permanent repairs can be made.

Advanced Leak Detection Techniques

Modern technology has opened up a range of advanced leak detection methods beyond basic visual and auditory inspections. Specialised thermal imaging cameras can detect temperature differences that reveal water leaks behind walls or under floors. Acoustic listening devices pick up the subtle sounds of escaping water, pinpointing leaks precisely. Fibre optic cameras provide live video footage of pipe interiors to identify cracks or punctures. Pressure testing involves monitoring pressure changes in pressurised plumbing to pinpoint flaws.


Other advanced techniques like electromagnetic pipeline locators, correlators, and moisture sensors use variations in signals, frequencies, and moisture levels to identify leaks accurately. Tracer gas testing involves injecting harmless gases like helium into pipes and detecting their escape to uncover hidden leaks. While these high-tech methods are extremely precise, they require expensive gear and expertise to implement correctly.

When faced with difficult-to-diagnose leaks, consulting professional leak detection services is the most effective solution. Their cutting-edge equipment and specialised training empower them to pinpoint even subtle leaks behind walls or under floors. This allows for targeted repairs, preventing exponential damage. Advanced leak detection provides peace of mind.
