Water Spray Fixed Systems Maintenance Checklist

Water spray fixed systems are designed to provide rapid, targeted fire suppression in high-risk areas – from transformers and conveyors to industrial equipment and fuel storage zones. These systems distribute water through carefully aligned spray nozzles that cool surfaces, control flames, and prevent heat spread. But like all suppression systems, reliability depends on regular inspection and testing.

Over time, strain­ers can clog, nozzles may corrode, and control valves can drift out of position. Without routine maintenance, these small issues can delay system activation or reduce coverage during an emergency. That’s why consistent testing and recordkeeping are critical to keeping these systems in top shape.

Our Water Spray Fixed Systems Maintenance Checklist helps facility teams perform thorough inspections and maintain system performance across all intervals, from weekly checks to long-term internal inspections.

What’s Inside the Checklist

Your downloadable checklist includes:

• Weekly / Monthly Tasks: Valve positioning, pressure gauge readings, strainer cleaning, and nozzle alignment checks.
• Quarterly Inspections: Supervisory device and alarm testing, deluge valve checks, and functional verification.
• Annual Maintenance: Full operational tests, main drain testing, nozzle inspection, and water supply verification.
• 5-Year Tasks: Internal pipe inspections for corrosion or blockages, valve rebuilds, and obstruction investigations.
• Post-Fire Event Procedures: Flushing, nozzle replacement, and full system restoration steps.
• Maintenance Log: A built-in section for documenting inspections, service intervals, and corrective actions.

Routine maintenance ensures that your system delivers fast, reliable water coverage when it’s needed most – protecting assets, equipment and personnel from fire damage.
