Start with what you have noticed
Pressure testing can help establish whether a particular circuit is losing water under suitable conditions. It is often part of narrowing the investigation, rather than a way of pinpointing the leak by itself.
Use isolation to ask a more specific question
Where the system permits, the engineer separates relevant sections and assesses their behaviour. The result helps direct subsequent tracing towards the circuit supported by the evidence. Appropriate checks are also used after plumbing repair to assess the affected system.
Signs that can prompt an investigation
- Several possible leaking circuits
- An isolated heating loop losing pressure
- A concealed supply needing assessment
- A repaired pipe requiring follow-up checks
