We have a two-zone fire sprinkler system, one is wet, the other is dry-pipe. There are no inside hose valves, just a small NFPA 13 building.
Does the fire pump size need to accommodate hose allowances?
The sprinkler calculations have no inside hose allowance. We would typically apply the hose allowance at the city tap, which would be upstream of the fire pump.
Thanks in advance.
