8 Common Dry Sprinkler System Problems
The Fire Code Authority · Updated November 11, 2026
Dry systems protect areas that could freeze, like parking garages and unheated warehouses. Their extra components create extra ways to fail.
The list
- 1. Water left in low points that freezes and splits pipe.
- 2. Air compressor problems that stop the system from holding pressure.
- 3. Slow trip times, so water takes too long to reach the heads.
- 4. Air leaks that cause the compressor to cycle constantly.
- 5. Corrosion inside pipe that holds moisture.
- 6. Valve rooms that aren’t kept heated.
- 7. Low points not drained on schedule before and during cold weather.
- 8. Dry sprinklers past their replacement or sample-testing interval.
