We confirm whether the leak is the cistern, the pan connector or the supply before any panel or tile is opened.
- Internal versus external leak: Interpret readings against operating conditions and equipment specification; do not assume a recharge is the answer.

- Cistern body and joints: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
- Moisture tracing before opening: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
