Water leaks can often be the silent culprit behind significant damage to your home, hidden in walls, floors, or underground pipes. You might not even notice them until it’s too late, but by then, the damage could be extensive, and your water bills could be through the roof. Early leak detection is crucial to prevent these issues and minimise unnecessary costs.
In this guide, we’ll explore the main leak detection tools used by professionals. We’ll also discuss why these tools are more effective than DIY options. You’ll also discover how Greenstar’s expertise and advanced technology can help you keep your home dry, safe, and leak-free.
As mentioned above leaks can also increase your water bills, resulting in unnecessary expenses. According to the ONS (Office for National Statistics), a staggering 19% of water put into supply is being lost as leakage. Wasted water from leaks can add hundreds of pounds to your annual bills. Early leak detection prevents these issues, saving you money and protecting your property.
Here’s where our professional tools come in. With the latest technology, we can quickly find hidden leaks. This helps prevent them from turning into expensive repairs. Professional leak detection tools are far superior to DIY methods, as they all but ensure your home stays dry and secure.
At Greenstar, we take pride in utilising the latest, most effective tools to detect leaks quickly and accurately. We focus on non-invasive methods to minimise disruption to your home while providing fast results.
Here are the key tools we rely on to identify hidden leaks:
Thermal imaging helps find leaks behind walls or under floors. It detects temperature changes caused by moisture. It’s non-invasive, fast, and accurate, providing precise data on leak location without causing damage.
For instance, in a home in Three Legged Cross, thermal imaging helped find a leak behind a wall. This avoided cutting drywall, and allowed us to fix the issue quickly.
Acoustic sensors pick up the sounds of flowing water. They help us locate leaks in hard-to-reach places, such as underground pipes or behind walls. It’s a fast, non-invasive method perfect for pressurised systems like hot water or heating pipes.
If a local home has a suspected leak in its heating system, plumbers will often start with acoustic listening devices. These devices detect water flow sounds and help locate leaks under the floorboards or in the walls. This way, you avoid expensive and invasive repairs.
Moisture meters measure the moisture level in materials such as wood, drywall, and concrete. They help identify hidden dampness that might otherwise be missed. This tool is crucial for detecting leaks early before they cause significant damage.
In a damp basement, a moisture meter can detect hidden moisture in the walls, indicating a slow leak that would otherwise go unnoticed. This tool helps Greenstar locate the source of the leak and repair it before further damage occurs.
Tracer gas detection uses a harmless gas to find leaks in hard-to-reach or underground pipes. This non-invasive method offers highly accurate leak location without disturbing your property.
If a garden irrigation system is leaking underground, we can use tracer gas detection. This method helps locate the leak without the need for expensive digging or disturbing the garden.
Pipe locators are important tools for tracing underground pipes. These devices blend electromagnetic signal tracing with acoustic feedback. This helps them locate leaks accurately, even if the pipes are buried deep underground.
Imagine a suspected leak in an underground irrigation system for a garden. Using a pipe locator, we can trace the path of the pipe and accurately identify the location of the leak.
Don’t wait for small leaks to become a bigger problem. Early leak detection is crucial for preventing costly repairs and maintaining your home’s safety. With Greenstar’s advanced leak detection tools, we can quickly locate and fix hidden leaks, saving you time and money.
Whether it’s a leak behind the walls or a more complex underground issue, our team of experts is here to help. We use cutting-edge technology for quick and precise leak detection. This approach ensures minimal disruption and ensures your home stays dry, safe, and leak-free.
