What if the feng shui ball doesn't turn?

Since water has not been added for a long time, whose house should be filled with water as much as possible when it is reopened. Then turn on the power switch to see if the water pump works. If it still works, the ball should spin. If not, it means that the pump has burned out (this kind of pump is easy to burn out when it works without water) and needs to be replaced with a new pump. The size of the new pump should also match the diameter of the ball. It is best to buy a national standard pump or one with the same parameters as the old pump.
