Underground water leaks can be a homeowner's nightmare, often leading to costly repairs and significant property damage if left unchecked. But how do you even know if you have a water leak underground? Since they’re hidden from plain sight, these leaks can go unnoticed for a long time, quietly causing havoc beneath your feet. In this guide, we’ll cover how to tell if you have a water leak underground, the signs to look out for, and what to do about it.
Underground water leaks aren’t just inconvenient—they can cause serious damage. From undermining your home’s foundation to skyrocketing water bills, the consequences can be both expensive and hazardous. Water can weaken the soil structure, leading to sinkholes or structural instability. Over time, the constant moisture can even cause mould growth, posing health risks to you and your family.
Beyond the structural damage, leaking water is also a waste of a valuable resource. Addressing underground leaks promptly is essential to avoid unnecessary expenses and environmental impact.
One of the first signs of an underground water leak is a sudden spike in your water bills. If your usage hasn’t changed but your bill has, it’s a strong indicator that water is escaping somewhere out of sight. Compare your current bill to previous months to spot any unusual increases.
Have you noticed damp or soggy patches in your garden even when it hasn’t rained? This could be a sign of water seeping up from a leak underground. In some cases, these areas might be greener than the rest of your lawn, as the leaking water is effectively overwatering that spot.
If you’re experiencing reduced water pressure in multiple areas of your home, it could be a sign of an underground leak. When water escapes through a crack or hole in the pipes, the pressure drops throughout the system, affecting taps, showers, and appliances.
Hearing the sound of running water when no taps are on? This could be a sign of water moving through a damaged pipe underground. Head to the quietest room in your house and listen carefully. If you hear water movement but know nothing is turned on, it’s worth investigating further.
Underground water leaks can cause the soil beneath your property to shift or erode, leading to cracks in walls, driveways, or even the foundation. If you notice new or widening cracks, especially near water lines, it could be due to an underground leak.
If puddles or sinkholes suddenly appear in your yard without any apparent cause, an underground water leak may be to blame. This happens when the soil becomes saturated and destabilises, creating dips or holes in your garden.
One of the most effective ways to find water leaks in your home is the water meter test. To do this, turn off all water-using appliances and taps in your house. Check the water meter and make a note of the reading. Wait at least an hour without using any water, then check the meter again. If the reading has changed, it indicates a leak somewhere in your system.
A pressure test involves checking the water pressure within your pipes. If the pressure is significantly lower than normal, it could suggest a leak. This method is typically carried out by professionals who can accurately measure the pressure and pinpoint the issue.
Leak detection dye can help locate underground leaks by highlighting water movement in the soil. Special sensors can also be used to detect sound vibrations caused by escaping water. These tools are highly effective and can help pinpoint the location of the leak without digging up your garden.
If you’re unsure about DIY methods or want a more accurate diagnosis, hiring a professional leak detection service is the best option. Experts use advanced equipment such as ground microphones, thermal imaging, and gas tracing to locate leaks with precision. At FS Group, we specialise in detecting and repairing underground water leaks, ensuring your property is safe and secure.
Older homes are more susceptible to underground leaks due to aging or corroded pipes. Over time, pipes can weaken, crack, or rust, leading to leaks. If your home was built decades ago, it’s worth checking the condition of your pipes to prevent future issues.
Ground movement from natural events like earthquakes or heavy rainfall can cause the soil to shift, putting pressure on underground pipes. This pressure can eventually cause pipes to crack or separate, leading to leaks.
Poor installation practices or using low-quality materials can result in underground leaks over time. Faulty joints or incorrectly fitted pipes are particularly prone to leaks. If you’ve recently had plumbing work done and notice any signs of a leak, it’s worth having it inspected.
Tree roots are naturally drawn to water sources, making underground pipes a prime target. Roots can grow around pipes, eventually cracking them as they expand. This is especially common if there are large trees near your water lines.
Knowing how to tell if you have a water leak underground is essential for protecting your property and saving on water bills. By keeping an eye out for the common signs mentioned above and using testing methods like the water meter test, you can detect leaks early and avoid costly repairs.
