The installer doesn’t have to worry about water bursts
3: What happens if the water level in the well drops below the inlet?
The motor power consumption drops
3: What happens if the water level in the well drops below the inlet?
The motor power consumption stays the same

4: 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.
4: Why is correct sizing of the submersible pump important?
Because too small a pump will pump the well dry.

4: Why is correct sizing of the submersible pump important?
Because too big a pump will ruin the taps due to too high pressure.
