Confirm that the symptom is hot-water only
Compare the affected outlet with cold water at the same fixture and with hot water elsewhere. Note whether there is no hot flow, reduced flow, delayed flow or a temperature concern. Do not change boiler, cylinder or immersion settings to reproduce the issue.
- One hot outlet affected
- Every hot outlet affected but cold flow normal
- Stored hot water appears limited or inconsistent
- Visible water around a cylinder, tank or hot pipe
