leak detection

Water leaks are sneaky culprits that can wreak havoc in any home if left unattended. As plumbing pros who’ve been around the block for more than 25 years, we’ve seen firsthand the headaches and costly damages that unnoticed leaks can cause. That’s why every homeowner must be clued up on how to detect leaks. It’s not just about saving money on water bills or preventing damage; it’s about maintaining a safe and healthy living environment for your family.

Knowing how to detect a leak, big or small, can be a game changer. Leaks can occur anywhere—from your kitchen to your bathroom or even underground. Fortunately, you don’t always need fancy equipment to spot them. Most leaks give away signs visible to the naked eye if you know what to look for. Moreover, using some basic household tools can help unearth even the most cunningly hidden leaks. Remember, early detection is key. It can mean the difference between a quick fix and a significant repair job, saving you time, money, and stress in the long run.

Let’s dive into how you can become a leak-detecting whiz, ensuring that your home stays dry and damage-free. Whether you’re just curious about what signs to watch out for or you’ve noticed something amiss and aren’t sure what to do next, we’re here to guide you every step of the way.

Understanding the Basics of Leak Detection

Leak detection is key to maintaining the health of your plumbing system and ensuring your household remains safe and dry. We start by understanding the signs that suggest a leak. These might include an unexpected increase in your water bill, the sound of running water when all taps are off, or damp patches forming on walls and ceilings. Recognising these signs early can save you from more significant and costly repairs down the line.

We’ll guide you through the different types of leaks that can occur in a home, from simple dripping taps to more severe hidden pipe leaks beneath your floors or within the walls. Each type demands a different approach and level of urgency. For example, a visible tap leak is usually a quick fix with the right tools, while underground or within-wall leaks can require more complex equipment and procedures to diagnose and repair.

Visual Inspection Tips for Identifying Water Leaks in Your Home

Visual inspections are your first line of defence against water damage. We recommend regular checks around your home to catch leaks early. Pay special attention to areas where leaks are common, such as under sinks, around the bases of toilets and tubs, and where pipes connect to appliances like dishwashers and washing machines. Look for signs like water stains, warping, or discolouration on your walls, ceilings, or floors.

Don’t overlook the exterior of your home. Check outdoor faucets, hose bibs, and sprinkler systems for leaks as well. Any pooling water or unusually damp patches in your garden could indicate a leak in your service line. By conducting these inspections regularly — we suggest seasonally — you can spot and address minor leaks before they escalate into bigger problems. Remember, some leaks can be slow and not always obvious, but over time, they can cause significant damage and lead to hefty repair bills.

Using Household Tools to Detect Hidden Leaks

Even if you’re not a plumbing pro, you can use several household tools to seek out hidden leaks. One effective method is to use a food colouring test for your toilet cistern. Just add a few drops of food colouring to the cistern, wait about 30 minutes without flushing, and check if the colour appears in the bowl. If it does, you’ve got a leak allowing water to seep through from the cistern to the bowl without flushing.

Another handy tool is your water meter. To check for hidden leaks using your water meter, ensure all water in your home is turned off, then watch the meter. If it continues to move, this indicates a possible leak in the system. This method is particularly useful for spotting more significant leaks that can otherwise remain undetected but can cause extensive damage over time.

When to Call in the Pros: Recognising Beyond-DIY Leak Situations

Sometimes, DIY methods just aren’t enough to manage or diagnose your plumbing issues — that’s when it’s time to call in the professionals. If you’ve tried the above methods and still suspect a leak, or if you’ve identified a major issue like a broken pipe, it’s crucial to contact a professional plumber immediately. Situations involving sewage leaks, water in contact with electrical lines, or substantial water damage also require professional attention.

Calling in skilled plumbers can prevent more extensive damage and ensure the problem is resolved effectively and safely. Professional plumbers have specialised tools and techniques that go beyond household remedies — things like thermal imaging cameras and acoustic detectors can pinpoint leaks that aren’t visible to the naked eye.


Handling leaks promptly and efficiently is crucial for maintaining the integrity and safety of your home. By using some simple household techniques, you can often catch and address minor leaks before they develop into bigger problems. However, knowing when to call in the professionals is just as important to ensure your home’s plumbing is well-maintained and functioning correctly.
