The Flow Detect notebook
A leak that only appears after showering
Use the sequence of events to frame the investigation.
Separate the possible routes
Supply connections, waste fittings and the enclosure do different jobs. A leak after use may require those parts to be considered separately.
A short timeline helps
Describe how long the shower runs before the signs appear, how long they last and whether basin or bath use has the same effect.
Avoid a cosmetic assumption
Fresh sealant may hide the symptom without resolving a concealed fault. The useful question is which route the evidence supports, then what work falls within the agreed repair.
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.
