IFC (2003) section 905.4 item 5 requires each standpipe to have a roof connection, though it also allows it to be located at the highest landing.

I have a four story motel with two standpipes with a combined system. I must install a roof manifold per code but I’m not sure if it should be one off each standpipe. I would say yes because the standpipe pipe is sized by the required hydraulic calculation procedure which utilizes both standpipes which share the required flow, so if there is only one roof manifold at the remote standpipe then the total flow could require larger pipe which in turn would make the initial calc procedure null and void. How many roof manifolds should I install? Any suggestions will be greatly appreciated, Ron Internal Virus Database is out-of-date. Checked by AVG Free Edition.
