I have 4 no's warehouse in a single compound. Each warehouse having 230 no's of sprinklers with 6" Main Riser Pipes & 6" Zone Control Valve Assembly each. Each of these 6" risers are connected from 8" header pipe from the Fire Pump.


Should i need to install Alarm Check Valves in each warehouse or is it enough to install one 8" Alarm Check Valve in Pump Room?
