1: What happens if the static water level is too low?
1: What happens if the static water level is too low?
The water level is brought down below the inlet of the pump
1: What happens if the static water level is too low?
2: What is the benefit of a slow increase in speed?
It keeps the motor current low
2: What is the benefit of a slow increase in speed?
It keeps pump movements at a minimum

5: Why is correct sizing of the submersible pump important?
Because an undersized pump will not be able to deliver the required flow and pressure and an oversized pump reduces energy efficiency, which increases operational costs.
5: Why is correct sizing of the submersible pump important?
Because too small a pump will pump the well dry.
