NFPA 25 is the standard most fire marshals use to judge whether a sprinkler system is being looked after. It is long and technical, but the schedule itself is simple once it is laid out.
Inspection schedule at a glance
| Frequency | What is checked | Who usually does it |
|---|---|---|
| Weekly / monthly | Control valves, gauges, alarm devices visible and in place | Building staff |
| Quarterly | Water-flow alarms, valve supervisory switches, main drain | Licensed contractor |
| Annually | Full system inspection, sprinkler heads, hangers, fire department connection | Licensed contractor |
| Every 5 years | Internal pipe inspection, gauge replacement or calibration | Licensed contractor |

Storage stacked within 18 inches of sprinkler heads is the number one finding, and it is free to fix. Walk your space before the inspector does.
