This is because if the suction hose is placed on the bottom of the tank, it will likely pick up any particles or debris that have settled there. By keeping the hose elevated, it ensures that only clean water is being sucked up, which is important for various applications such as pumping water for irrigation or filtering water for drinking purposes.Rate this question:
