If you manage a commercial building in Kansas and you're thinking “we had our annual inspection, we're good” — you might be right. Or you might be missing quarterly inspections, a 5-year internal check, or documentation that your insurance carrier will ask for.
Here's the full picture of what NFPA 25 actually requires.
The short answer
Fire sprinkler systems in Kansas must be inspected on multiple schedules per NFPA 25: weekly, monthly, quarterly, annually, and every five years. The annual inspection is the most commonly known — but it's only part of the full compliance picture.
The full NFPA 25 inspection schedule
Weekly inspections
Weekly inspections are required for control valves and gauges on pre-action and dry sprinkler systems. If you have a wet pipe system (the most common type), weekly inspections are generally not required. Wet pipe systems have simpler monthly requirements instead.
Monthly inspections
Monthly inspections for wet pipe systems include checking gauges and alarm valves. This is typically something building staff can handle with proper training — but it needs to be documented.
Quarterly inspections
Quarterly inspections are where most commercial building owners fall short. NFPA 25 requires quarterly checks of:
- Waterflow alarm devices and signal devices
- Control valves
- Fire department connections (FDC)
- Hydraulic nameplates
These quarterly inspections need to be done by a qualified contractor and documented. Many property owners only call a contractor once a year — for the annual — and skip quarterly documentation entirely.
Annual inspections
The full annual inspection covers everything: all sprinkler heads (condition, coverage, clearance from storage and obstructions), all valves, alarm devices, gauges, pipes and hangers, and the overall system condition. You get a written report with test results and any deficiencies.
This is the inspection most fire marshals and insurance carriers ask about. If you only do one inspection per year, this is the one — but quarterly documentation still matters.
5-year inspections
Every five years, NFPA 25 requires more comprehensive work:
- Internal pipe inspection (to check for corrosion, scale, and debris)
- Sprinkler head sample testing — a sample of heads from your building gets tested by a certified lab
- Gauge replacement or recalibration
- Obstruction investigation where indicated
The 5-year inspection is easy to miss, especially if your system is older or you've had multiple contractors over the years. We regularly encounter buildings that have had consistent annual inspections but haven't done a 5-year internal check.
What about fire pumps and backflow preventers?
If your system includes a fire pump, that pump needs monthly no-flow (churn) tests and annual full-flow performance tests — separate from the sprinkler inspection. Backflow preventers on fire protection systems need annual testing as well.
A fully NFPA 25-compliant maintenance program covers all of these, not just the sprinkler heads.
Practical takeaway for Kansas property owners
The biggest compliance gaps we see in Kansas are:
- Missing quarterly inspections or lack of documentation
- Missed 5-year internal inspections
- No records of fire pump monthly tests
- Lapsed backflow preventer testing
If you're not sure whether your building is fully up to date, the honest answer is to schedule an assessment. We'll look at your records, walk the system, and tell you exactly where you stand.
