Frequently Asked Questions
Customers often have questions about water mains leak detection, so we’ve answered some of the most common queries to help you understand how our service works across Liverpool and the North West.
We use specialist, non-invasive technology to locate leaks in underground or concealed mains pipes. Equipment such as tracer gas, ground microphones, and acoustic listening devices allows us to pinpoint the leak without unnecessary excavation. This ensures the problem is found quickly and accurately, helping to reduce water loss and avoid unnecessary disruption to your property or surrounding area. By identifying the exact source of the leak, targeted repairs can be arranged immediately, saving you both time and money while protecting your property from further damage.
Yes, our non-invasive methods are specifically designed to avoid unnecessary digging. Using advanced tools, we can trace leaks in underground mains pipes with accuracy, meaning excavation is only required once the exact location has been identified. This prevents large-scale disruption to your property or land and ensures any access work is limited to the precise spot where repairs are needed. By working this way, we save you money on unnecessary labour, minimise property damage, and provide fast, reliable results you can trust.
Typical signs of a mains water leak include unexplained increases in your water bill, damp patches appearing in gardens or driveways, reduced water pressure inside your property, or visible pooling of water in outdoor areas. In some cases, you may also hear unusual sounds from the pipework. Because mains leaks are often underground, they can remain hidden for a long time, leading to wasted water and potential damage. If you notice any of these signs, contacting our team quickly ensures the issue is diagnosed and dealt with before it develops into a more serious problem.
Absolutely. We operate a 24/7 emergency service and are ideally located to respond quickly to urgent mains water leaks across nearby towns such as Bootle, Southport, Warrington and throughout Cheshire and the wider North West.
