Water storage tank level indicators should be tested for accuracy at five-year intervals. This testing frequency ensures that the gauges and indicators remain reliable and provide correct readings, which is vital for the safe and effective operation of sprinkler systems and water storage management. Regular testing helps in identifying any calibration issues or mechanical failures that may arise over time.

The five-year interval is generally adopted based on industry standards and best practices, striking a balance between regulatory compliance and practical operational considerations. Testing at this interval helps ensure that any inaccuracies that could lead to improper water levels, thereby affecting fire protection systems, are addressed in a timely manner.
