Who it's for, and who should skip it

Good fit if

  • 115 V homes

Pros and cons

Pros

  • 231 ft head
  • Built-in check valve
  • Stainless shell

Cons

  • 3-wire needs a control box
  • 230 V only
  • Pro install

Limitations to weigh

  • Well pumps usually need a licensed installer, the right wire size and a pressure tank sized to the pump.
  • Check whether your circuit is 115 V or 230 V before ordering; many well pumps are wired for 230 V.
  • Maximum head is where flow drops to zero; at your lift the pump moves less than its maximum flow. Size it with the sizing calculator.
