Extended-Interval Inspection and Testing Requirements

Fire Protection System

Did you know that NFPA 25 Standard (2011 edition) has extra fire system inspection, testing, and maintenance requirements for Water-Based Fire Protection Systems? These requirements are in addition to the regular monthly, quarterly and annual procedures.

NFPA 25 Testing Requirements For Extended-interval Inspection and Testing

These extended-interval fire system inspection and testing requirements include, but are not limited to the following:

  • Dry-Pipe and Preaction Systems – pressure test for air leakage every 3 years.
  • Dry-pipe Systems – full flow trip test every 3 years.
  • Internal inspection of check valves – every 5 years.
  • Internal inspection of piping – every 5 years.
  • Gauges – recalibrate or replace every 5 years
  • Sprinklers – sample testing or replacement. The required frequency for fire sprinkler system testing or replacement varies from every 5 years to every 75 years depending on the type of sprinkler and the environment in which the sprinkler is installed.
