You have lined up # 1 main fire pump for supply to one of the deck hydrants. You have personally checked the opening of all the required valves and started the pump. The pump discharge shows a pressure of about 5 bar, but the deck hydrant doesn't get any water. You line up # 2 fire pump and get water on the deck hydrant when the pump discharge pressure shows only 2.5 bar. State the reason why # 1 Fire pump was unable to send water to the deck hydrant?
