Water Tank Preventive Maintenance Checklist Annual

This annual preventive maintenance checklist covers inspections for water tanks with electronic and mechanical controls. Tasks include reviewing manufacturer guidance, applying lockout procedures, and documenting results. Inspect the tank interior, fittings, hatches, ladders, and manholes for corrosion; clean and test sight glasses, valves, drains, and controls. Service the level control panel by cleaning exterior and interior components, checking wiring and relays for damage or overheating, and verifying alarm, control, and communication circuits. Confirm level indicators and control devices function correctly, check for contamination, and return the system to service.
