NFPA13. I have not seen any mention in this code about the color of sprinkler piping although its common to use the red color. is there any recommendation on this topic?
Base standard does not require color coding
There is no color coding in NFPA Codes, but red is the usual color used. You can also label pipe FIRE PIPE or FIRE SPRINKLER PIPE additionally to the red color.
