The Overwatch Advantage
We combine the technical execution of a licensed fire contractor with the fiscal scrutiny of a professional advocate. We provide total system lifecycle management. Overwatch self-performs your mandatory inspections, from annual flow tests to 5-year internal pipe investigations, ensuring your infrastructure is safe and your documentation is audit-ready.
Our direct service model targets the "silent killers" of fire sprinkler systems. We don't just find leaks; we perform the repairs and implement corrosion management (MIC) strategies that prevent catastrophic failures. We take ownership of your compliance so you can focus on your property, knowing your life-safety assets are 100% Fire Marshal Ready.
Anatomy of an NFPA 25 Inspection
Our technicians follow a rigorous protocol to verify system readiness, moving beyond simple visual checks to functional performance testing.
Verifying the water supply isn't restricted by debris or partially closed valves by measuring static and residual pressures.
Opening terminal ends and main pipes to check for obstructions and microbiologically influenced corrosion (MIC).
Testing flow and tamper switches for fire alarm panel accuracy and central station dispatch verification.
Hangs from the pipe. Standard for finished office/retail ceilings where aesthetics and coverage are key.
Points toward the ceiling. Typically used in warehouses, mechanical rooms, and exposed piping areas.
Protrudes from walls. Ideal for hotel rooms, narrow corridors, and areas where overhead piping is restricted.
The main assembly controlling water flow and alarm signals. Must remain locked in the open position.
Exterior inlet for the Fire Department to pump additional water and pressure into the building system.
Wet Pipe System
Water is always present in the pipes. This is the fastest response time and most cost-effective solution for heated buildings where freezing is not a concern.
Dry Pipe System
Pipes are filled with pressurized air or nitrogen until a head is triggered. Specifically designed to prevent freezing bursts in unheated garages, attics, or loading docks.
