Why it matters

Green Expert rates this 1.5 HP PSC pump at up to 5,000 GPH at zero lift and 68.5 GPM at 10 ft, with 33 ft maximum lift. That 10 ft figure is more useful than most makers give.

Its float can be clipped to the body for automatic on/off or held up for continuous running. It comes with two adapters, a 25 ft cord and a reinforced thermoplastic body.

Who it's for, and who should skip it

Good fit if

  • Flooded basements
  • Temporary sump use
  • Large pools

Look elsewhere if

  • Sewage or grey water with solids
  • Unattended running on manual models

Pros and cons

Pros

  • Flow at 10 ft published
  • Adjustable float
  • 25 ft cord

Cons

  • Large
  • One-year warranty
  • Avoid expandable hoses

Limitations to weigh

  • 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.
  • A garden-hose outlet limits flow; use the larger discharge where the pump has one.
