Fully agree.
Fully agree. Interconnection is required. A control valve is required at each
stairway riser.
Thanks,

Agreed. Four separate FDC's - in a building with no sprinklers and likely
without any annunciation of where in the building a fire is working - would be
extremely challenging for the first responding company. The intent is for
each FDC, including multiple FDCs that pump into a single
Yes. There is no exception for dry manual standpipes. Also, I tap the cap
at the bottom and add ball drips to remove any moisture after testing.

A parking garage is being supplied by a Manual Dry Standpipe in each exit
stairwell, 4 total. Per NFPA-14 (2013) 7.5 would these need to be
interconnected? There are no sprinklers in the garage, only standpipes in the
stairwells.
