Do I Have a Leak? Signs Pointing Underground

While some leaks are obvious like  underground water leaks – a puddle in the basement or a constantly running meter –  underground leaks can be stealthy. Here are some telltale signs to watch for:

  • Unexplained Increase in Water Bill:

This is a major red flag, especially if your water usage habits haven’t changed.

  • Soft Spots in the Yard:

 Water leakage can saturate the soil, causing spongy or uneven areas in your yard.

  • Cracks in Foundation: 

Water pressure underground can lead to cracks in your foundation, potentially causing structural damage.

  • Mold Growth: 

Leaks can create a damp environment perfect for mold to flourish.

Principle of the Acoustic Water Leak Detectors:

When a pressurized underground water pipe develops a leak, water flows through it into the surrounding soil at high speed causing:

  • The pipe vibrates at the water leak, transmitting sound through the pipe where it can be detected at water valves, hydrants, water meters and other remote contact points on the water pipe. The sensitive headphones, microphone and amplifier with noise filters helps the water leak professional pinpoint the water leak location.
  • The water leak jets and pipes induce vibration in the soil which transmits to the surface, where it can be picked up as ground-borne noise.

Water leak noises are not transmitted well by non-metallic pipe materials. Taking readings at the valves is not enough: the sections between valves must also be checked with a ground microphone for water leaks.

Acoustic Leak Detection

Acoustic Leak Detection equipment

Acoustic leak detection is a method used by professional plumbers to locate hidden leaks.  These sensitive microphones amplify the sound of running water, allowing plumbers to pinpoint the leak’s location by following the noise.  This method is most effective in quiet environments and for leaks in metal pipes.

Thermal Imaging

Thermal Imaging Camera

Thermal imaging cameras can detect temperature variations in the ground caused by escaping water, helping to identify the leak’s general area.  Hot water leaks will show up as bright spots on the thermal image, while cold water leaks will show up as dark spots.  This method is not as precise as other methods, but it can be a helpful tool for narrowing down the search area.

Ground Penetrating Radar (GPR)

Ground Penetrating Radar (GPR) equipment

Ground penetrating radar (GPR) is a sophisticated technology that sends electromagnetic pulses into the ground and measures their reflection.  By analyzing the reflected signals, plumbers can create an image of what’s buried beneath the surface, including pipes and potential leaks.  GPR is a very accurate method, but it can be expensive and is typically only used by professional leak detection companies.

Video Pipe Inspection

Video Pipe Inspection camera

Video pipe inspection is a method that uses a small, waterproof camera inserted into the pipes to provide a live video feed of the interior. This allows plumbers to inspect the pipes for damage, corrosion, and leaks.  This method is most effective for leaks in sewer lines and other large diameter pipes.

DIY Leak Detection Tools

  • Water Meter Test

A water meter test is a simple DIY method that can help you identify a potential leak.  Turn off all the water in your house and monitor the water meter. If the dial continues to move, it suggests a leak somewhere in the system, possibly underground.  This method is not foolproof, but it can be a good starting point.

  • Listening Sticks and Ground Microphones

Listening sticks and ground microphones are simple tools that amplify sounds underground, allowing you to listen for the hissing or rushing water indicative of a leak.  These tools can be helpful for locating leaks in close proximity to the surface, but they can be difficult to use and interpret.

  • Moisture Meters

Moisture meters are handheld devices that measure moisture levels in the soil. While not foolproof, a spike in moisture content near your house could indicate a leak.  This method is most effective in areas with relatively dry soil conditions.

Wireless robust test rod for acoustic water leak detection. The AquaTest T10 water leak detector test rod brings innovative technology and ergonomic design. Its strength lies in the pre-location of water leaks in pipe networks. The AquaTest T10 is the first Sewerin test rod that without a receiver.

Things to Consider When Choosing an Ultrasonic Leak Detector

  • Price: Ultrasonic leak detectors range in price from around $50 to $200.
  • Ease of use: Some ultrasonic leak detectors are more complex to use than others.
  • Features: Some ultrasonic leak detectors have features like filters and gooseneck designs that can make them more versatile.
  • Warranty: Choose a leak detector with a good warranty in case it malfunctions.

When to Call a Professional

If you are unable to locate the leak yourself, or if the leak is severe, it is best to call a professional plumber. Professional plumbers have a variety of tools and techniques that can help them locate and repair leaks quickly and efficiently.
