5: What is a key installer benefit of the voltage protection in SQ/SQE?
Fewer service visits
6: 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.
6: Why is correct sizing of the submersible pump important?
Because too small a pump will pump the well dry.
