Fire Sprinkler Service & NFPA 25 Inspections
Is your fire sprinkler system ready to perform? Best Defense Fire Protection & Security provides the expert testing, maintenance, and certification required to keep your facility safe and compliant with Wisconsin state codes.
Keeping Your System Mission-Ready
Wisconsin mandates that fire sprinkler systems be inspected at least once a year. Beyond compliance, regular service prevents the most common causes of system failure—such as closed valves or internal corrosion.
- Annual & Quarterly Inspections: Full NFPA 25 testing of valves, gauges, and alarms.
- Backflow Certification: Essential testing to protect your facility’s potable water.
- Fire Pump Testing: Weekly or annual performance runs to ensure adequate pressure.
- Internal Pipe Investigations: Specialized 5-year checks for MIC (corrosion) and obstructions.

Is Your Pipe Rotting from the Inside Out?
NFPA 25 requires an internal pipe inspection every 5 years. We use advanced rotating inspection scopes to look for MIC (Microbiologically Influenced Corrosion) and sludge. Finding these issues early saves you from catastrophic pipe failure and massive water damage later.
