- Why the fire pump cannot pump water?
- 2020.11.17
- The fire pump cannot pump water: Some users have measured that although the vertical distance from the water reservoir or water tower to the water surface of the fire pump is slightly less than the head of the fire pump, the water lift is still small or unable to pump water. The reason for fire pumps is often that the pipe is too long, the water pipe has many bends, and the resistance loss of the water flow in the pipe is too large.
