The point to understand
A heating gauge reports the state of the system, not the location of a fault. Accessible valves, appliance findings and concealed circuits may all need consideration.
Put it into practice
Bring together the dates of pressure changes, recent work and any boiler engineer’s notes. Useful circuit boundaries can make later tests more informative.
Keep the limits in view
Repeated topping-up is not a diagnosis. Discuss the system with an appropriate professional rather than opening floors on the strength of the gauge alone.

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.
