Many components require quarterly inspections (water flow alarms, control valves, gauges), and internal pipe inspections are required every 5 years. Your local Authority Having Jurisdiction (AHJ) in Wilmington may impose requirements beyond NFPA 25 minimums, so confirm specifics with your inspector.

Contractors listed in Wilmington commonly service Wet Pipe, Dry Pipe, Kitchen Hood, Pre-Action, and Deluge systems. When selecting a contractor, confirm they have specific experience with your system type — not all fire suppression companies service every system. Kitchen hood suppression and clean agent systems (FM-200, CO₂) require specialists distinct from standard wet-pipe sprinkler contractors.
