What Is NFPA 25?
NFPA 25 is the national standard for keeping a building’s fire sprinkler system — and the rest of its water-based fire protection — inspected, tested, and working. Here’s what it covers, how the schedule works, and what it takes to show you’ve kept up.
The definition
NFPA 25 is the Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, published by the National Fire Protection Association. The current edition is 2026.
It covers the ongoing care of fire sprinklers, standpipes, fire pumps, water storage tanks, and private fire mains — everything that uses water to fight a fire. It’s not about installing the system; it’s about proving, over its whole life, that the system will actually work the day there’s a fire.
The single most common reason a sprinkler system fails is a shut-off valve left closed after maintenance — which is exactly why NFPA 25’s routine checks exist.
How the schedule works
NFPA 25 sets different check frequencies for different parts of the system — some weekly, some yearly, some every five years. You don’t need every rule to understand the shape of it:
- 01Frequent, simple checks (weekly or monthly) — control valves are in the open position, gauges read normal. Building staff can often do these.
- 02Quarterly checks — water-flow alarms and the fire department connection are working.
- 03Annual — a full inspection and test of the system by a qualified contractor.
- 04Every five years — deeper internal inspections and testing.
The point isn’t the exact list — it’s that the schedule is layered, ongoing, and can’t be collapsed into one yearly visit. Each tier catches a problem the others can’t see.
Who is responsible
NFPA 25 places ultimate responsibility for the system on the building owner — even when the work is contracted out. Staff can handle the simple weekly and monthly checks; the quarterly, annual, and five-year work generally needs a qualified contractor. Either way, the obligation to keep it done, and to show it, stays with the owner.
When something is found, NFPA 25 sorts it into noncritical (doesn’t stop the system working), critical (impairs the system’s ability to control a fire), or impairment (the system can’t function) — which sets how fast it must be fixed.
What changed in the 2026 edition
Two updates worth knowing
- A sprinkler system containing ice now counts as impaired — it must be fully thawed before it’s considered back in service.
- Hose valve inspection moved from annual to quarterly.
A program built on the 2023 or earlier edition may not reflect these — another reason the edition your jurisdiction adopted matters.
Which edition applies to you
The current edition is not necessarily the one your building answers to. 2026 is the current NFPA 25 edition, but a standard only becomes enforceable when a state or local authority adopts it — on each jurisdiction’s own timeline. Many are still enforcing an earlier edition.
The version that governs your building is the edition your state and local AHJ has adopted. Confirm the adopted edition for your jurisdiction.
What it takes to show you’ve kept up
A sprinkler system passes or fails on one thing when it’s checked: can you show every required inspection and test was done, on schedule? NFPA 25 requires the records be kept and available to the authority having jurisdiction on request. Missing records make it hard to demonstrate the system was maintained.
- 01A record for each check — weekly, monthly, quarterly, annual, five-year — done on time.
- 02Deficiencies documented, classified, and tracked to correction.
- 03Records retained and ready when the AHJ or insurer asks.
Where EvidLY fits
EvidLY is the record layer for the fire protection systems your property depends on. Every NFPA 25 sprinkler check — alongside the fire alarm, the kitchen suppression, and the exhaust service — is captured, dated, and held as a sealed, tamper-evident record, on the schedule each requires. When anyone asks whether the sprinkler system is current, the proof is already there, in one place.

On a property policy with a Protective Safeguards Endorsement, your automatic sprinkler system is the P-1 system named in it — and NFPA 25 is the standard it’s serviced to.

What is NFPA 25?
The Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems — it governs the ongoing care of sprinklers, standpipes, fire pumps, and water tanks. The current edition is 2026.
How often does a sprinkler system need to be inspected?
On a tiered schedule — some checks weekly or monthly, water-flow alarms quarterly, a full inspection and test annually, and deeper internal work every five years. The exact frequency depends on the component and system type.
Who is responsible for NFPA 25 compliance?
The building owner, even when the work is contracted out. Staff can do the simple weekly and monthly checks; the annual and five-year work generally needs a qualified contractor.
What changed in the 2026 edition of NFPA 25?
Among other updates, a system containing ice now counts as impaired (it must be fully thawed before returning to service), and hose valve inspection moved from annual to quarterly.
