Method
Line Tracing
Knowing the route is half of finding the leak.
Line tracing identifies the path of a pipe using a signal transmitter and receiver, so investigation and excavation know exactly where the line runs.
How it works
- Transmitter connected to an accessible point
- Receiver follows and marks the route
- Depth estimated where conditions allow
Limits, stated plainly
- Metallic or traceable lines respond best
- Non-conductive lines need alternative methods
- Accuracy varies with depth and soil

Quick answers
Is Line Tracing invasive?
No. The method works from surfaces and accessible points; if a small access point is needed to confirm a finding, it is discussed before anything is opened.
Can Line Tracing be used on its own?
Line Tracing is strongest when paired with a confirming method. Findings are only reported once verified, which is why single-method clues are labelled as such.
