Q:Why do we need to stop the pump?
And the pump at the start, if the valve opening pump, then the pump outlet pressure (head) is very small, so the pump flow will be great, the pump power is very large, causing the start-up current is very large. In addition, the starting current of the motor itself is also very large. These two factors add up to the possibility of overloading the motor, resulting in failure to start or even burn the motor.
