Water Restoration

Water leaks can be incredibly costly and damaging, especially when they occur underground. These leaks can go unnoticed for a long time, causing extensive damage to your property and leading to skyrocketing water bills. 

Knowing how to find a water leak underground is crucial for homeowners to prevent potential disasters. In this blog, we’ll explore the signs of an underground water leak, the methods to detect it, and the steps you can take to fix the problem.

Signs of an Underground Water Leak

Unexplained Increase in Water Bills

One of the first signs of an underground water leak is a sudden and unexplained spike in your water bill. If you notice a significant increase without any change in your water usage habits, it might be an indication that water is leaking somewhere underground.

Damp or Soggy Spots in Your Yard

An underground water leak often manifests as damp or soggy spots in your yard. If you notice areas of your lawn that are consistently wet or muddy, even during dry weather, it could be a sign of a leak beneath the surface.

Decreased Water Pressure

A noticeable drop in water pressure can also indicate an underground leak. If your water pressure seems lower than usual, it might be due to water escaping from a hidden pipe underground.

Low water pressure is a potential sign of an underground leak. 

Unusual Sounds of Running Water

If you hear the sound of running water when all your taps are turned off, it could be a sign that water is leaking somewhere underground. These sounds are often more noticeable at night when the house is quiet.

Foundation Cracks or Sinkholes 

Over time, an underground water leak can cause the soil to erode, leading to foundation cracks or even sinkholes in severe cases. If you notice new cracks in your foundation or sudden depressions in your yard, it’s crucial to investigate further.

How to Find a Water Leak Underground

Understanding methods to detect an underground water leak requires a combination of observation and the use of specific tools. Here are some effective methods to detect an underground water leak:

  1. Visual Inspection

Start with a thorough visual inspection of your property. Look for the signs mentioned above, such as damp spots, unusual vegetation growth, and foundation cracks. Pay close attention to areas near water lines and pipes.

  1. Water Meter Test 

One of the simplest ways to detect a leak is to use your water meter. Turn off all water fixtures and appliances in your home, then check the water meter. If the meter continues to run, it’s a clear indication that there is a leak somewhere in your system.

  1. Pressure Testing

 A pressure test can help identify if there is a leak in your plumbing system. This test involves measuring the water pressure in your pipes and comparing it to standard levels. A significant pressure drop could indicate a leak.

  1. Acoustic Leak Detection 

Acoustic leak detection involves using specialized listening devices to detect the sound of water escaping from pipes underground. Professionals often use this method to pinpoint the exact location of a leak without digging up large areas.

  1. Thermal Imaging

Thermal imaging cameras can detect temperature differences caused by leaking water. This method is particularly useful for identifying how to find a water leak underground, as well as in walls and under floors, allowing a professional to see where water might be accumulating from.

A thermal imaging camera detects leaks that aren’t visible to the naked eye.

  1. Soil Probe Testing 

Soil probe testing involves inserting a probe into the ground to detect moisture levels. This method can help identify the general area of a leak, especially in larger properties.

Steps to Fix an Underground Water Leak

Once you’ve identified an underground water leak, addressing the issue promptly is essential to prevent further damage. Here are the steps to take:

  1. Shut Off the Water Supply

Before attempting any repairs, turn off the water supply to prevent further leakage. This will also make it safer to work on the damaged pipe.

  1. Excavate the Area 

Carefully excavate the area around the suspected leak. Be cautious not to damage other pipes or utilities during this process. It’s often best to hire a professional, especially if the leak is deep underground.

  1. Inspect and Repair the Pipe

Once the damaged pipe is exposed, inspect it thoroughly to determine the extent of the damage. Depending on the severity, you may need to replace a section of the pipe or apply a patch. Use only the appropriate materials and follow plumbing codes to ensure a durable repair.

Even if a leak from a pipe seems small, it should be repaired immediately.

  1. Test the Repair 

After fixing the leak, turn the water supply back on and monitor the area for any signs of continued leakage. Check your water meter and water pressure to ensure the problem has been resolved.

  1. Backfill and Restore the Area

Once you’re confident that the leak has been repaired, backfill the excavation site with soil, compacting it as you go to prevent future settling. Restore any landscaping or paving that was disturbed during the repair process.

Preventing Future Leaks

Preventing future leaks is just as important as repairing existing ones. Here are some tips to help you avoid future underground water leaks:

  1. Regular Maintenance

Regularly inspect your plumbing system for signs of wear and tear. Replace old or damaged pipes before they become a problem.

  1. Monitor Water Usage 

Keep an eye on your water usage and bills. Sudden increases can be an early warning sign of a leak. According to the U.S. Environmental Protection Agency, “A good method to check for leaks is to examine your winter water usage. A family of four likely has a serious leak problem if winter water use exceeds 12,000 gallons per month.”

  1. Install Leak Detectors 

Consider installing leak detection devices that alert you to leaks in your plumbing system. These devices can help you catch leaks early before they cause significant damage that are accompanied by costly repairs.

  1. Proper Landscaping 

Be mindful of where you plant trees and shrubs. Their roots can grow into and damage underground pipes. Avoid planting large trees near water lines.
