What are the reasons for Underground water leaks and water pipe leaks?

Corrosion:

  • Over time, pipes can corrode due to soil exposure, water minerals, and other environmental factors. Corrosion weakens the pipe material, making it more prone to leaks.

Age of Pipes:

  • Older pipes made of materials like galvanized iron or lead may deteriorate with age. The aging process can result in cracks, rust, or weakened joints, leading to leaks.

Ground Movement:

  • The ground may move due to shifting soil, earthquakes, or construction activity, which could strain underground pipes. Water leaks may occur due to cracks, fractures, or misalignment brought on by this tension.

Tree Roots:

  • Tree roots frequently cause water leaks underground. Seeking out water sources, roots can pierce pipes, resulting in damage and eventual leakage. This is especially typical for older concrete or clay pipes.

Freezing and Thawing:

  • Pipe damage can result from the expansion and contraction of water caused by freezing and thawing in colder climates. Water that has frozen within pipes might break or rupture.

High Water Pressure:

  • Excessively high water pressure can strain pipes, leading to leaks. Pressure spikes may occur due to issues with the municipal water supply or the home’s water pressure regulator.

Poor Installation:

  • Improper installation of pipes, including inadequate joint sealing or incorrect pipe materials, can contribute to leaks over time.

Chemical Corrosion:

  • The corrosion process can be sped up by exposure to specific chemicals in the soil or water, mainly if the pipes are not resistant.

Manufacturing Defects:

  • Pipes with manufacturing defects may be more susceptible to leaks. These defects can include weak spots, poor welds, or irregularities in the pipe material.

Abrasion:

  • Because of the movement of rocks or other abrasive elements in the soil, pipes may get damaged. Leaks may eventually result from the abrasion’s weakening of the pipe walls.

Water Hammer: 

  • A sudden shift in the water’s direction or flow can result in a water hammer, a shockwave that travels through the pipes. Repeated stress like this over time can lead to leaks and damage to pipes.

Underground water leaks can be prevented and their effects reduced with routine maintenance, early identification, and rapid resolution of any problems. It is best to speak with a licensed plumber if there are indications of a water leak so they can evaluate the issue and make the required repairs.

How does a plumber find a water leak underground?

Detecting a water leak underground is a specialized task involving a combination of experience, skill, and various tools and techniques. Here is an overview of how a plumber typically finds a water leak underground:

1. Customer Input:

  • Plumbers often start by gathering information from the property owner. This may include any noticeable signs of a leak, such as damp areas, unexplained increases in water bills, or the sound of running water where it shouldn’t be.

2. Visual Inspection:

  • The plumber might find possible indications of a water leak by visually inspecting the outside and internal areas of the home. This can entail searching the driveway, basement, or yard for damp or discolored areas.

3. Pressure Testing:

  • Plumbers may perform pressure tests on the water system to check for pressure drops, which could indicate a leak. This involves pressurizing the pipes and monitoring pressure levels while isolating different sections of the plumbing system.

4. Acoustic Leak Detection:

  • Plumbers use specialized equipment, such as ground microphones, geophones, or electronic listening devices, to detect the sound of water escaping from pipes. They can narrow down the leak’s location by carefully listening at various points along the suspected pipe.

5. Infrared Thermography:

  • Infrared cameras can be used to detect temperature variations on the surface. Water escaping from a pipe can cause changes in the temperature of the surrounding soil, which may be visible through infrared imaging.

6. Dye Testing:

  • Fluorescent dyes can be introduced into the water system. The appearance of the dye on the surface can help confirm the location of a leak. This method is often used in conjunction with other techniques.

7. Ground-Penetrating Radar (GPR):

  • GPR is a non-invasive method that uses radar pulses to create subsurface images. Plumbers can use GPR to identify anomalies or voids in the ground caused by water escaping from pipes.

8. Soil Probing:

  • Physical inspection of the soil around the suspected area can also be helpful. Plumbers may use probes to check for unusually wet or soft soil, which could indicate a water leak.

9. Meter Reading:

  • Monitoring water meters over a period can help identify continuous water usage, even when there is no apparent consumption in the property. A sudden spike or constant flow may indicate a hidden leak.

10. Isolation and Repair:

  • Once the general location of the leak is identified, plumbers may isolate the affected section of the plumbing system and make the necessary repairs. This may involve excavation to access the damaged pipe.

 11. Listening Devices:

  • Highly skilled technicians use specialized listening devices equipped with headphones and microphones. They can identify the leak’s location by listening to the sound of running water underground as it travels through pipes.

12. Pressure Testing with Balloons: 

  • Plumbers may perform pressure testing in the area using air or nitrogen-filled balloons. These balloons help detect variations in pressure caused by leaks.

13. Video Inspections:

  • Plumbers utilize video cameras to inspect pipes and identify leaks. These cameras can navigate through pipes, providing visual evidence of the leak’s location and extent of damage.

14. Thermal Imaging Cameras

  • These cameras detect temperature differences, which can indicate water leakage. Areas with abnormal temperature patterns may suggest an underground leak.

It’s important to note that the specific methods used can vary based on the nature of the plumbing system, the type of pipes involved, and the conditions on the property.

Plumbers often use these techniques to locate and repair underground water leaks accurately. If you suspect a water leak, it is advisable to confer with a professional plumber to conduct a thorough assessment and diagnosis.
