Preparation comes first
The investigator needs to assess isolation, connected equipment and the proposed test boundary. Shared supplies require particular coordination.

A detected signal can help direct attention, but the tracer can travel through voids or ground before emerging. The surrounding construction matters.
Keep access in view
Detection informs an access decision. Physical access is still required for a concealed plumbing repair.
