As do a few on the left side.  It's common to see demand-based requirements for 
both standpipe and sprinkler systems.   How many ESFR systems are out there 
with 2-way FDC's?   If system demand is 1,600gpm ...

Subject: Standpipe FDC Inlets

How many of you put a 4 way FDC on every 1000 gpm standpipe system or a 5 way 
on parking garage without sprinklers and 4 or more standpipes? I have seen many 
buildings with two standpipes and a 2 way FDC.

2007, NFPA 14, 7.12.3 states: Fire Department Connection sizes shall be based 
on the standpipe system demand and shall include one 2½ in. inlet per every 250 
GPM.

Phoenix at one time required one inlet per 250 gpm on sprinkler systems until 
we did a tire warehouse and needed a 14 inlet FDC.
