How to Prevent Costly Property Damage with an Underground Water Leak Detector

Although fire is the greatest fear homeowners face, in reality, fires are a very rare threat to worry about. What is a far more common cause of property damage though, is flooding. And flooding doesn’t occur just by itself unless there is a serious natural disaster. In other words, before there’s flooding, there’s usually a leak that can originate from anywhere, like for instance a burst pipe or a leaky appliance.

Since most of the leaks caused by appliances can be detected by eye, it’s the underground leaks that we should be worried about more. Luckily, there’s a device that can help detect underground leaks before major damage occurs. An underground water leak detector can help you precisely locate leaks in a range of underground systems, including plumbing and gas pipes, which are buried underneath concrete, soil, pavement, timber and other materials. This way, there’s no need for expensive and time-consuming excavation.

When it comes to choosing the right underground water leak detector, it’s recommended going for one that uses tracer gas. Whether it’s helium or a hydrogen-nitrogen combination of tracer gas, these types of leak detectors are known for providing the most accurate results as they are lighter than air and can penetrate through the densest of surfaces quickly, pinpointing the smallest of leakage points. Another benefit of opting for helium or hydrogen-nitrogen gas is the fact that they are non-polluting, non-toxic for humans, do not react with other gases and as such are safe to use.

It’s also recommended to go for devices that offer a sensitivity as low as 25ppm (0.0025%) concentration. Not only does a higher sensitivity result in more accurate readings, but it can also reduce the operation cost because it allows the tracer gas to mix with the ambient air more. To further reduce the running costs of the device, make sure to choose a model powered by a rechargeable Ni-MH battery.

Most of the time, a water leak detector is used by building inspectors, however, that doesn’t mean that other people can’t purchase this device. If you’re a homeowner who wants to have the peace of mind that there’s no leaks on their property, then make sure to get informed about how to properly use this device.

While detectors may differ, most of them operate similarly. To locate a leak, you need to empty the system and then pressurise it with the tracer gas. Then, you need to use the detector’s ground probe by placing its rubber cup on the surface over the system. While the tracer gas rises towards the surface, the probe can locate the exact position of the leak accurately.
