Good day, I need someone help me with the minimum size for a class II standpipe and branch lines. According to NFPA 14 7.6.1 class I and class III standpipe shall be at least 4 in. I have a class II design (by others) with standpipe of 3 in and branch lines with 2 in. I need to approve these drawings with the local authority (Panama) and they state we need to comply with NFPA 14.


Thanks in advance.
