If a fire pump supplies both the fire sprinkler system and the site fire hydrants, does the fire pump gpm need to be capable of suppling both? (Fire sprinkler demand 900 gpm and site fire hydrant demand 2000 gpm for a total of 2,900. Can the fire pump be size at 750 for the fire sprinkler/hose demand or does it have to be a 2000 gpm so it can supply both the sprinkler and site fire hydrant flows of 2900 gpm?) The supply is city water and there is a bypass on the fire pump. The city supply comes into the fire pump house and goes out to single loop that supplies both the fire sprinkler systems and the site fire hydrants. (The city flow and psi is adequate to meet the site fire flow at 20-psi.)
