Water Tank Cleaning explained
Annual tank cleaning with photographic before and after evidence, which is what auditors expect to see against your risk assessment.
- Annual inspection schedule: Agree the interval against manufacturer guidance, operating hours and equipment condition rather than assuming one schedule suits every asset.
- Photographic evidence: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
- Debris and scale removal: Water condition, cleaning and equipment suitability should be checked against the manufacturer’s requirements.
- Sampling before return to use: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
Interpreting the reported fault
A planned visit should establish condition and identify deterioration. An existing fault may need separate diagnosis and parts. Agree which assets, cleaning tasks, functional checks and records are included, and base the interval on manufacturer guidance and operating conditions.
- Reported symptom: annual tank cleaning required by a water safety plan
- Record when the problem started and any recent changes
- Keep fault codes and model details for the assessment
