NFPA 13 or 14 (07ed) Situation:
Water supply with BFP supplying one wet system and one standpipe system. Wet system has a control valve in the riser room but we would like not to put a control valve on the standpipe riser / bulk main in order to connect the FDC to it father down in the building. Each stairwell standpipe will have a control valve to isolate it off the standpipe bulk main. AHJ is requiring an additional control valve on the bulk main in the riser room which would require us to now run an additional 250ft of 4in pipe to the FDC location. Of course he won't state where he gets this requirement just that he wants it. I have piped several buildings this way in the past. Have I been doing it wrong all these years?
