Understanding underground line routes can help plan a leak investigation or excavation, but mapping and leak detection are different tasks.
When mapping may be useful
- Unknown service line paths
- Outdoor renovation near existing utilities
- Unclear relationship between a wet spot and buried plumbing
- Complex properties with multiple service connections
Before any digging
Contact 811 or the relevant utility-location service before excavation and follow all utility-owner and local rules. Private-property line locating may require separate arrangements.
Clarify deliverables
Ask whether the scope includes line tracing, depth estimates, a sketch or map, and whether actual leak pinpointing is separate.
What to share during your first call
Have your property address ready. Describe when the issue began, where you have noticed water or unusual conditions, any water meter changes and whether immediate damage is occurring. Ask about the diagnostic process, the assigned professional, and charges before authorizing work.
