I am using a recent fire pump test as my water supply information and calculating the system back to the pump discharge flange. My question is when picking up hose allowance, NFPA dictates 250GPM. Normally I would put 100gpm inside and 150gpm outside. Since I am calculating back to the pump discharge flange, do I still need to include the 150 outside house? If so, where?
