How Plumbers Find a Leak You Can't See
Underground leak detection uses acoustic listening equipment, pressure testing, and sometimes tracer gas to pinpoint exactly where a buried water line is leaking, without digging up your entire yard to search for it. This precision is what turns a potentially large excavation into a small, targeted repair.
Finding the leak precisely is what keeps the fix small instead of turning into a full yard excavation.
Signs of an Underground Leak
These symptoms commonly point to a leak below the surface.
- Unexplained wet or unusually green patches in your yard
- A noticeable, unexplained increase in your water bill
- Your water meter keeps moving with everything in the home off
- Lower-than-normal water pressure with no other obvious cause
- The sound of running water near an underground line’s path
What to Check Before Requesting Leak Detection
A little info helps plumbers narrow down the search area.
- Confirm the leak by checking your water meter with everything off
- Note the general path of your main water line if you know it
- Look for unusually wet, soft, or green patches in your yard
- Ask whether the detection service includes locating the exact spot before any digging
