Elusive Leaks: Here’s how they happen and How an Expert Leak Detector can help
Here’s how they happen and How an Expert Leak Detector can help
Plumbing leaks aren’t always obvious. Some start small, quietly dripping behind walls, under floors, or even beneath your garden paving. By the time you notice the signs—a damp patch, mold growth, or a shockingly high water bill—significant damage may already have been done.
That’s why Alpha Plumbing’s certified leak detectors combine advanced technology with decades of experience to find the source of the problem without unnecessary mess or disruption. Whether it’s a mysterious damp patch, an unexplained spike in your water bill, or the sound of running water when every tap is off, we get to the truth quickly—and repair it properly. Our leak detectors are skilled and equipped to find hidden leaks inside your home or an underground burst pipe. We provide accurate diagnosis and professional water leak repair so you can get back to normal without the drama.
Why Hidden Leaks Happen
Pipes have a lifespan, and over time they can weaken due to rust, corrosion, and general deterioration. Soil movement, water pressure changes, and environmental factors can speed up the process. With regular leak detection services, our team can identify weak points before they fail — saving you the cost of emergency repairs.
Debris, grease, and mineral deposits build up inside pipes, restricting water flow. This increases internal pressure, which can cause cracks or burst joints. Blockages can also force water to back up and seep into surrounding structures. Regular drain cleaning can prevent clogs and reduce the risk of leaks.
South African weather can be unpredictable—hot days followed by cold nights cause pipes to expand and contract. Over time, this movement creates small cracks that eventually leak. Proper pipe insulation, especially in exposed areas, is key to preventing this type of damage.
Incorrectly installed plumbing or the use of substandard materials almost always leads to leaks. While DIY repairs may seem cheaper, they often mask the problem rather than solve it—leaving you with a bigger repair bill later.
Alpha Plumbing is registered and accredited with the Institute of Plumbing of South Africa (IOPSA) and the Plumbing Industry Registration Board (PIRB) giving you the peace of mind that all repairs meet industry best practices and safety regulations. Seeking professional plumbing services for installations and repairs is essential to ensure that the job is done right the first time, preventing an unexpected and costly problem later.
