If your building has a sprinkler system, it’s covered by NFPA 25 — the standard for inspection, testing and maintenance (ITM) of water-based fire protection systems. Fire marshals enforce it, and your insurer will usually ask for proof you’re following it. Once you know what’s due when, most of it is routine.
The schedule at a glance
| How often | What gets checked |
|---|---|
| Monthly | Gauges and control valves |
| Quarterly | Alarm devices and fire department connections |
| Semiannually | Waterflow alarm and valve supervisory switch tests |
| Annually | Sprinklers, pipe, fittings and hangers from the floor; main drain test; antifreeze solution; dry pipe valve partial trip test; fire pump flow test |
| Every 3 years | Dry pipe valve full trip test |
| Every 5 years | Internal pipe assessment for obstructions; gauges replaced or recalibrated |
| By sprinkler age | Fast-response heads sampled at 20 years, standard heads at 50, dry sprinklers at 10 — then every 10 years |
Fire pumps add their own routine: a no-flow “churn” test weekly or monthly depending on the driver, and a full flow test once a year.
Your jurisdiction adopts a specific edition of NFPA 25, and some intervals have changed between editions. We schedule to the edition your fire marshal enforces, not a generic checklist.
Who can do the work
In Texas, sprinkler inspection and testing is performed by contractors licensed through the State Fire Marshal’s Office. Each completed inspection gets a service tag on the riser, and you get a written report listing every deficiency.
What happens if you miss one
Missed inspections are one of the most common citations a fire marshal writes, and gaps in your records can complicate an insurance claim after a loss. Small problems also get bigger: a corroded valve or a failing gauge is cheap to fix during a routine visit and expensive to fix in an emergency.
