Underground & Water Line Leaks
Underground Leak Detection in Snohomish, WA
Not every hidden leak is under the slab. Lines running between the water meter, the street, and your home or building can also develop leaks in the ground outside the foundation footprint.
How This Differs From a Slab Leak
A slab leak occurs specifically in a pipe beneath a building's concrete foundation. An underground leak, by contrast, is in a buried line outside that footprint — often the main service line from the meter, an irrigation line, or a line running between structures. Detection methods overlap, but the search area and likely causes differ.
Signs of an Underground Line Leak
- A soggy or unusually green patch of lawn along the line's likely path
- Water pooling at the surface with no recent rain
- A drop in water pressure at the point of entry to the building
- A water bill increase without a corresponding slab-related symptom indoors
