Water Tanks for Fire Protection Maintenance Checklist

Behind every effective fire protection system lies a dependable water source … and that means your fire water storage tanks must always be inspection-ready. Whether built from steel, concrete, or fiberglass, these tanks provide the critical reserve needed for sprinklers, hydrants, and standpipe systems to perform as designed.

But without consistent maintenance, leaks, corrosion, sediment buildup, or faulty level indicators can quietly undermine reliability. Routine inspections help verify tank capacity, pressure, valve positions, alarm functions and heating systems, ensuring water availability and system performance when it matters most. A well-maintained tank not only supports your fire suppression systems but also extends the lifespan of your entire fire infrastructure.

Our Water Tanks for Fire Protection Maintenance Checklist simplifies that process, giving your facility team a clear, structured guide for inspections, documentation, and compliance.

What’s Inside the Checklist

Your downloadable checklist includes:

• Weekly / Monthly Tasks: Check water level and temperature, inspect control valves, verify vent and overflow clearance, and assess tank exterior condition.
• Quarterly Tasks: Test alarm and supervisory devices and inspect circulation or heating systems for operational consistency.
• Annual Maintenance: Conduct full external inspections, remove sediment, calibrate level indicators, and verify heater and valve performance.
• 5-Year Tasks: Perform internal tank inspections, thickness and corrosion testing, structural integrity verification, and recoating or repair documentation.
• Post-Fire Event Procedures: Confirm tank refill, inspect for leaks or damage, and verify system reset readiness.
• Maintenance Documentation Log: A built-in section to record inspection intervals, findings, and corrective actions.
