I have a specification that states nothing less than 1" pipe shall be used for a sprinkler system. Is there anywhere in NFPA 13 that prohibits the use of 3/4" pipe? I know in the 2007 Edition 8.15.19 states new installations shall have a minimum of 1" outlets for piping supplying sprinklers below ceilings. This section doesn't specifically come out and state that all piping must be 1". In 8.15.19.4 all piping with the exception of a 4" nipple shall be 1" minimum. Am I missing something or is 3/4" allowed per NFPA 13?
