Foam-Water Sprinkler Systems Maintenance Checklist

Foam-water sprinkler systems are the ideal solution for areas where flammable liquids or high-temperature hazards make water alone insufficient, like industrial plants, warehouses and aircraft hangars. These hybrid systems combine the cooling effect of water with the smothering power of foam, providing rapid, reliable fire suppression when seconds matter.

However, their performance depends entirely on consistent upkeep. Over time, foam concentrate can separate or degrade, strain­ers can clog, and valves may corrode or stick. Neglecting maintenance could result in poor foam quality or delayed activation, compromising both safety and compliance.

Our Foam-Water Sprinkler Systems Maintenance Checklist helps ensure every component – from tanks and proportioners to discharge nozzles – works flawlessly during an emergency.

What’s Inside the Checklist

Your downloadable checklist includes:

• Weekly / Monthly Tasks: Valve and gauge checks, foam tank inspection, and sprinkler head condition monitoring.
• Quarterly Tasks: Supervisory and alarm device testing, and foam-water valve checks.
• Annual Maintenance: Foam quality sampling, proportioner calibration, full operational testing, and system flushing.
• 3–5 Year Tasks: Foam/water ratio testing, tank inspection, and flow meter calibration.
• Long-Term (10-Year+) Maintenance: Sprinkler head replacement cycles and gauge recalibration.
• After Fire Event Procedures: Piping flush, tank refill, and complete system restoration.
• Maintenance Log: Built-in section for recording all inspection intervals and technician notes.
