The point to understand
Testing an entire installation can show a change without identifying which circuit is involved. Suitable isolation can create a more specific question.
Put it into practice
Known valves and system drawings help establish a testable section. Record which section was checked and the conditions of the test.
Keep the limits in view
Pressure behaviour does not by itself show where to open a floor. It helps guide further tracing and needs a suitable system arrangement.

Every installation has its own history and access constraints. These notes explain the approach, rather than diagnose your property. Add your observations to a draft so the actual situation can be discussed.
