How Plumbers Spot Hidden Leaks Underground

When water starts bubbling up in your yard—or even worse seeping through your foundation—you need to find the cause. But how do plumbers track down leaks that you can't see?

It's a mix of detective work and cutting-edge tech. Here's what the experts do.

1. Sound-Catching Tools

These gadgets pick up the noise of water escaping from a pipe. Using super-sensitive mics, plumbers listen for hissing or dripping sounds through dirt, concrete, or walls. It's like underwater listening for pipes.

2. Heat-Seeing Cameras

Water leaks can change how warm or cold nearby surfaces are. Heat cameras spot these changes helping plumbers zero in on leak areas—under floors or foundations.

3. Pipe Finders and Ground-Scanning Radar

If nobody knows where the pipe is, plumbers use tracking tools or ground-scanning radar to map out the plumbing system underground before looking for leaks.

4. Pressure Checks
