TMV Servicing & Legionella Compliance explained
TMV servicing and legionella monitoring are delivered together, so one visit produces one compliance file instead of two disconnected records.
- TMV register and intervals: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
- Temperature and failsafe records: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
- Scale management: Water condition, cleaning and equipment suitability should be checked against the manufacturer’s requirements.
- Integrated compliance file: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
Interpreting the reported fault

- Reported symptom: joining up mixing valve servicing with the L8 control scheme
- Record when the problem started and any recent changes
- Keep fault codes and model details for the assessment
