Why it matters

Aquastrong rates the ESU100PM at up to 4,500 GPH at 5 ft and 30 ft of lift from a 1 HP motor. It drains to about 1/5 in.

The 1-1/4 in NPT discharge comes with an elbow and snap adapters for 3/4, 1 and 1-1/4 in hoses. It has a mechanical seal and thermal overload protection.

Who it's for, and who should skip it

Good fit if

  • Pools and hot tubs
  • Flooded basements
  • Window wells

Look elsewhere if

  • Permanent sump pits (a sump pump with a switch suits better)
  • Sewage or grey water with solids
  • Unattended running on manual models

Pros and cons

Pros

  • High flow
  • Adapters included
  • Thermal protection

Cons

  • Manual only
  • Short cord
  • Import brand

Limitations to weigh

  • Manual pumps run only while switched on; stay with the pump so it doesn't run dry.
  • Rated flow is at little or no lift; through a garden hose or up a stairwell, expect much less.
