Wet-Pipe Sprinkler Systems: submittal requirements

Fire suppression submittals are code documents as much as product data. The AHJ may review alongside the engineer, so listings, hydraulic calculations, and working drawings need to be complete and consistent.

What reviewers expect in a wet-pipe sprinkler systems package

  • Sprinkler head data with K-factor, temperature rating, and response type per hazard area
  • Hydraulic calculations tied to the working drawings
  • Working drawings with pipe sizes, head layout, and hanger locations
  • Valve, switch, and device data — all UL listed / FM approved as specified
  • Fire pump and controller data where applicable
  • Material certifications for pipe and fittings (schedule, joining method)

Field tip

Submit the calc package and working drawings together — approving heads without calcs is provisional at best, and many AHJs simply won't review a split package.
