Unvented vs Vented Hot Water Cylinders: Key Differences & Best Choice for Your Home

New Paragraph

At ONit Building Services Ltd, we know how important it is to spot leaks early before they cause significant damage to your home or business. Whether it's a dripping tap, hidden pipe leak, or a potential burst behind the walls, early leak detection can save you thousands of pounds in repair costs and prevent health hazards like mould. In this guide, we'll take you through the leak detection process, explain how hidden leaks can wreak havoc, and show you why timely action matters.​ What is Leak Detection? Leak detection is the process of locating and measuring the unwanted loss of water, gas, or other fluids within a system. Using advanced equipment such as acoustic sensors, thermal imaging cameras, pressure tests, and tracer gases, ONit Building Services Ltd can quickly identify hidden leaks that are otherwise difficult to detect. By spotting leaks early, we help prevent property damage, avoid costly repairs, and reduce water waste, ensuring a safe, dry, and healthy environment for you and your family.​ 1. The Process of Leak Detection The first step in leak detection involves a comprehensive inspection of your property. Our experts begin by speaking with you about any noticeable symptoms, such as damp patches, musty smells, or unusually high water bills. From there, we use specialised tools to confirm the presence and location of the leak.​ We combine non-invasive techniques like acoustic leak detection, which listens for water escaping from pipes, and thermal imaging, which identifies temperature differences in walls or floors. Moisture meters track the migration of dampness through surfaces, and tracer gas tests identify leaks in difficult-to-access areas. With our expertise, we can accurately locate the leak, providing you with clear repair options and peace of mind.​ 2. Why Leak Detection is Crucial Leaks, if left unchecked, can lead to severe property damage. Moisture can compromise structural integrity, cause timber rot, and even lead to mould growth, which poses significant health risks. Fast detection helps mitigate these risks, saving you from expensive repairs and ensuring your home remains safe and dry.​ For businesses, leaks can disrupt operations, cause downtime, and increase repair costs. ONit Building Services Ltd uses the latest leak detection technologies to ensure minimal disruption, fast results, and efficient repairs that keep your home or business running smoothly.​ Methods of Leak Detection Leak detection involves several methods tailored to different leak types and locations. Here's a look at the most common techniques we use:​ Internal Systems For internal systems, we monitor flow, pressure, and temperature. Smart meters and IoT sensors track water usage in real-time, helping us identify discrepancies that might indicate a leak. These systems are highly efficient for both small residential and larger industrial buildings, providing instant alerts when something's amiss.​ External Systems For external systems, we use acoustic sensors to listen for leak noise and thermal cameras to detect temperature changes behind walls or under floors. Tracer gas detection is especially effective for pinpointing small leaks in complex pipe networks. These methods are ideal for detecting hidden leaks that may be too difficult to spot with the naked eye.​ Manual Techniques While technology plays a big role in modern leak detection, manual techniques remain invaluable. We start by performing simple checks around sinks, cisterns, and appliances, followed by a water meter test to track any hidden leaks that may be impacting your system. For visible leaks, we use techniques like dye testing to trace water movement and identify the source.​ Finding Hidden Wall Leaks One of the most challenging leaks to detect is a hidden wall leak. These leaks often begin small but can quickly cause significant damage if left unchecked. Early identification is key, and ONit Building Services Ltd has the tools and expertise to detect hidden leaks before they turn into a major problem.​ Visual Signs of a Hidden Leak Look out for damp patches, peeling paint, or wallpaper that lifts. These are early indicators that water may be leaking behind your walls. Other signs include warping or soft spots on wood, swelling floors, or tiles coming loose.​ Non-Visual Clues If you notice a musty smell or a rise in humidity, it could be a sign of hidden moisture. Also, listen for quiet drips or hissing sounds when no taps are on. Unexpectedly high water bills are another clue that there might be a leak somewhere.​ At ONit Building Services Ltd, we use advanced equipment like moisture meters and acoustic leak detectors to find the source of these hidden leaks without causing unnecessary damage to your property.​ Mould Growth and Risks Leaks and mould go hand-in-hand. If left untreated, even small leaks can lead to extensive mould growth in just 24--48 hours. Mould not only damages your property but also poses serious health risks, including respiratory issues, skin irritation, and allergies.​ How Mould Grows Mould spores thrive in damp conditions, particularly in areas like walls, ceilings, and underfloor spaces. Within a week, untreated leaks can lead to significant mould colonisation, affecting your home's air quality and the structural integrity of materials like drywall and wood. The best way to prevent mould is to act quickly. The faster you address the leak, the less time mould has to spread, saving you both time and money on repairs.​ Cost of Leaks and Prevention Leaks increase utility bills and cause direct expenses like plumber fees, repairs, and detection services, plus indirect losses from property damage, health risks, and higher insurance. Prevent future leaks with regular inspections, smart detectors, and pipe insulation.​ Contact ONit Building Services Ltd for Leak Detection Services If you suspect a leak or have noticed signs of dampness in your home or business, don't wait for the damage to worsen.
