NFPA 25 Changes: The Records You Need to Keep
There is a common saying: "If it isn't documented, it didn't happen."
Historically, many building owners felt that as long as they had a current service tag hanging from their riser, they were compliant. However, the 2023 and 2026 editions of NFPA 25 (Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems) have significantly sharpened the requirements for what must be kept in your files.
The goal of these changes is clear: to ensure that if a fire occurs, there is a verifiable paper trail proving the system was maintained according to the manufacturer's original specifications.
New Mandatory Documentation
The most significant administrative update in recent years is the explicit requirement for property owners to maintain manufacturer's literature for all installed components.
In the past, having the "O&M Manual" was a recommendation. Now, it is a requirement. You must have data sheets and maintenance instructions for:
- Sprinkler heads (specifically specialized heads like ESFR or Dry-Type)
- Fire pump controllers and drivers
- Backflow preventers
- Pressure reducing valves (PRVs)
Pro Insight: Inspectors are now tasked with referencing this literature during their ITM (Inspection, Testing, and Maintenance) tasks. If you cannot produce the manufacturer's data sheet for a specific valve, the inspector technically cannot verify if it was maintained correctly.
The "Life of Installation" Records
There are certain documents that can never be purged. These must be kept for as long as the system is in the building. If you lose these, you may be forced to pay for professional "as-built" recreations or hydraulic re-calculations.
Original Acceptance Test Results: The "Birth Certificate" of your system. This proves the system worked at 100% capacity when it was first turned over by the contractor.
As-Built Drawings: A map of every pipe and head in the building.
Hydraulic Nameplates: The mathematical proof that your water supply can handle the hazard.
Initial Records of Components: A detailed inventory of exactly what was installed (brands, models, and quantities).
The ITM Retention Formula
One of the biggest points of confusion is how long to keep routine inspection reports. NFPA 25 uses a specific formula: Records must be retained for a period of 1 year after the next inspection, test, or maintenance of that type.
Here is what that looks like in practice for your 2026 filing system:
- Monthly/Quarterly Reports: Keep for at least 13-15 months (until the next year's cycle is complete)
- Annual Inspection Reports: Keep for 2 years
- 5-Year Test Records (Internal Pipe, Gauge Calibrations, Hydrotests): Must be kept for 6 years
- 10-Year Test Records: Keep for 11 years
The Danger of Early Purging: If a Fire Marshal asks for your 5-year internal pipe inspection report and you threw it away after three years, your system is technically non-compliant, even if the test was performed.
Documentation for Electronic Monitoring
The 2026 edition introduces clearer protocols for electronic monitoring. If your system uses smart sensors for pressure monitoring or electronic tamper switches, you must now keep records of the signal verification.
It is no longer enough to say the switch "clicks." You must have a record showing that the signal was successfully received at the Fire Alarm Control Panel (FACP) and, where applicable, the central monitoring station.
Impairment and Deficiency Logs
When a system breaks, the clock starts ticking. The 2026 edition places a heavy emphasis on "Impairment Management." You are required to keep a log of:
- When the impairment was identified
- Who was notified (the latest code explicitly requires local Fire Department notification for both emergency and preplanned impairments)
- The corrective action taken
- The date the system was returned to service
Note: NFPA 25 now suggests that "Critical Deficiencies" should be repaired within 30 days. Having a dated log proving you met this window is your best defense against insurance liability.
Digital vs. Physical: Which is Better?
NFPA 25 allows for digital record-keeping, provided the records are "accurate, secure, and easily retrievable."
While digital folders (like a secure cloud drive) are excellent for long-term archiving and preventing fire/water damage to the paperwork, we still recommend a hybrid approach. Keep a physical site binder in the riser room for the Fire Marshal's immediate review, and maintain a digital master file at your corporate office for insurance audits.
Don't Let Paperwork Be Your Weakest Link
Fire protection is a technical field, but it is governed by legal standards. If your documentation is incomplete, your system is technically "deficient" in the eyes of the law.

Your NFPA 25 Documentation Strategy
Keep your records compliant with 2023 and 2026 edition requirements:
- Mandatory Literature: Maintain manufacturer data sheets and maintenance instructions for all installed components (sprinkler heads, fire pump controllers, backflow preventers, PRVs)
- Life-of-Installation Records: Never purge original acceptance test results, as-built drawings, hydraulic nameplates, or initial component inventory
- Monthly/Quarterly Reports: Retain for 13-15 months
- Annual Inspection Reports: Retain for 2 years
- 5-Year Test Records: Retain for 6 years
- 10-Year Test Records: Retain for 11 years
- Electronic Monitoring: Keep signal verification records showing successful receipt at FACP and central monitoring station
- Impairment Logs: Document when impairment identified, who was notified (including Fire Department), corrective action taken, and date returned to service
- Critical Deficiencies: Repair within 30 days and keep dated log proving you met this window
- Hybrid Approach: Physical site binder in riser room for Fire Marshal, digital master file at corporate office for insurance audits
