At Plumbing Pros LLC, we deal with underground pipe leaks every day. These leaks waste water, damage property, and drive up bills fast. Detecting them early saves you money and prevents costly repairs. Here’s what you need to know about causes, warning signs, detection methods, and why calling a licensed plumber is the right move.

Causes of Underground Pipe Leaks

Underground leaks don’t happen without a reason. The most common causes include:

  • Aging pipes – older pipes corrode, crack, and weaken over time.

  • Shifting soil – heavy rain, erosion, or ground movement stresses pipes until they fail.

  • Tree roots – roots search for water and break into pipes.

  • Improper installation – poorly installed pipes develop weak spots and leaks.

Signs You May Have an Underground Pipe Leak

Watch for these red flags:

  • Higher water bills with no change in usage.

  • Wet or soggy spots in the yard or driveway.

  • Low water pressure throughout your home.

  • Strange hissing or gurgling sounds near plumbing fixtures.

  • Foundation cracks or shifting caused by water under the home.

Ignoring these signs can turn a small leak into major structural damage.
