Tanks not equipped with supervised water level alarms connected to a constantly attended location shall be inspected how often?

• A. Weekly
• B. Daily
• C. Monthly
• D. Quarterly

Answer: (C)

The key idea is that when a water storage tank isn’t connected to a supervised alarm that reports to a person at a constantly attended location, a human check is needed on a regular, predictable basis to confirm the tank’s status and readiness. Monthly inspections provide a practical cadence to verify the water level is adequate, the gauge and access are functioning, and there are no leaks, sediment buildup, or obstructed fill lines that could compromise an emergency supply. Daily or weekly checks would be unnecessarily burdensome for a static storage tank, while quarterly or longer intervals could allow problems to go unnoticed. If an alarm were actively supervised and monitored, the interval could be extended, but without that supervision, monthly inspection is the appropriate requirement.
