5-Year Fire Sprinkler Inspection | NFPA 25 & Title 19 – Southern California


5-Year Fire Sprinkler Inspection Services – Southern California

California law requires commercial fire sprinkler systems to undergo a thorough 5-year inspection that goes beyond annual checks — including internal pipe obstruction investigations, full system trip tests, valve inspections, backflow preventer testing, and complete documentation for your local Authority Having Jurisdiction (AHJ).
