NFPA-14 2019 Edition. There is a new section in NFPA 14 - Section 18.104.22.168.1:
The pressure required at the fire department connection for manual standpipes shall not exceed the working pressure of the system components of the standpipe system or sprinkler system when the system is a combined system.
Does anyone have any idea why this was added?
It seems to me that the maximum pressure at the FDC would be 175psi as this is what the sprinklers are rated.
Pumping at that pressure I would never get the 100psi required at the top of the most remote riser.
Or am I interpreting this section incorrectly?
Thanks in advance.
