What's Included in a 5-Year Fire Sprinkler Inspection
Five-year inspections are a more involved NFPA 25 requirement that examines the interior condition of fire sprinkler piping and investigates potential obstructions affecting system performance.
Internal Pipe Examination
Inspect the interior of fire sprinkler piping at required intervals to assess condition, buildup, and structural integrity.
Obstruction Investigation
Investigate potential blockages, foreign material, or corrosion products that could restrict water flow through the system.
Water Sample Analysis
Collect and review water samples from system drains where required to identify microbiologically influenced corrosion or sediment concerns.
System Valve & Drain Review
Verify main drain, inspector's test, and system valve conditions to support the internal inspection process.
Flow & Pressure Verification
Confirm system flow and pressure characteristics align with design expectations during the five-year evaluation.
Fitting & Connection Assessment
Review accessible fittings, connections, and components for signs of deterioration revealed during internal inspection.
Coverage Impact Review
Assess whether internal conditions or obstructions could affect sprinkler coverage or system reliability.
Inspection Documentation
Provide detailed records of internal findings, obstruction investigation results, and recommended corrective actions.
Corrective Action Planning
Outline pipe flushing, cleaning, replacement, or repair options when internal conditions require follow-up work.
Five-year inspection scope follows NFPA 25 requirements and may vary based on system type, pipe material, water supply, property use, and local authority having jurisdiction (AHJ). FDC can help determine the right approach for your commercial system.

Why 5-Year Fire Sprinkler Inspections Matter
Internal pipe conditions are not visible during annual inspections. The five-year NFPA 25 cycle is designed to catch obstructions, corrosion, and buildup inside piping before they compromise system performance when it matters most.
- Required every five years under NFPA 25 for most sprinkler systems
- Reveals internal pipe conditions that annual inspections cannot detect
- Identifies obstructions that could block water flow during a fire event
- Helps commercial properties avoid costly emergency system failures
- Supports AHJ compliance and insurance requirements for building owners
- Provides a documented baseline for long-term system maintenance planning
