The Flow Detect notebook
Finding a leak beneath a concrete floor
Understand why access should follow the evidence.
The floor changes the investigation
Depth, pipe material, surrounding layers and the available system access influence which methods may help. No single tool works equally well in every arrangement.
Combine the clues
A route plan, pressure result and suitable tracing can provide complementary information. A warm or wet patch is useful context rather than a guaranteed repair position.
Plan for what follows
Necessary access for the agreed plumbing repair is included. Reinstating screed, floor finishes or other building surfaces is a separate responsibility.
Put the information into context
This guide explains common investigation principles. Your property, the available access and the actual test findings determine the right next step. It is not a diagnosis of an unseen system.
