Short Answer
NFPA 25 governs the inspection, testing, and maintenance of water-based fire protection systems — mainly sprinklers, standpipes, and fire pumps. It sets different frequencies for different tasks, ranging from weekly visual checks to a five-year internal pipe inspection. Most facility managers only need to track a handful of these directly; the rest are handled by your service contractor.
What Falls Under NFPA 25
If your building has wet or dry sprinkler systems, standpipes, private fire service mains, or a fire pump, NFPA 25 applies. It’s the standard referenced by insurance carriers and fire marshals when they ask “when was this last inspected?”
The Practical Schedule
Weekly or Monthly (Often Handled In-House)
- Visual check that control valves are open and unobstructed
- Gauge readings on wet systems (checking for normal pressure)
- Fire pump churn test, if your building has one (typically weekly)
Quarterly
- Waterflow alarm devices
- Certain valve supervisory signals
Annually
- Full sprinkler system inspection, including a sample of sprinkler heads
- Standpipe hose and cabinet inspection
- Fire pump annual performance test
- Main drain test
Every 5 Years
- Internal piping inspection for obstruction
- Standpipe hydrostatic test in some occupancies
Staying Ahead of It
Most compliance problems don’t come from ignoring the schedule — they come from not knowing which task is due when, especially across a multi-building portfolio. Keep inspection reports in one place, ask your service provider to flag upcoming 5-year requirements well in advance, and don’t treat “inspected” and “compliant” as the same thing — a report with deficiencies still needs documented correction before your next audit.
Who Can Do This Work
NFPA 25 inspections must be performed by a qualified, typically licensed, fire protection contractor — this isn’t a task for general building maintenance staff, even for the more frequent visual checks in some jurisdictions.

Frequently Asked Questions
What’s the difference between inspection, testing, and maintenance under NFPA 25?
Inspection is a visual check for obvious issues, testing verifies the system actually functions as designed, and maintenance is the corrective work.
Do I need a fire pump test if I don’t have a fire pump?
No — fire pump testing only applies to buildings with a fire pump installed as part of the system.
What triggers a 5-year internal pipe inspection?
It’s a standing requirement under NFPA 25 regardless of system age, though older systems may need it evaluated more frequently.
