Why it matters

The FSP900C is the 3/4 HP version of FLUENTPOWER's float-switch pump: up to 3,300 GPH and 29 ft of head, which FLUENTPOWER notes are separate peak ratings.

Auto mode starts above about 4 in and stops near 2 in; manual mode drains to about 1/2 in. It includes hose adapters, a check valve and a 26 ft nylon rope.

Who it's for, and who should skip it

Good fit if

  • Larger flooded areas
  • Temporary sump use
  • Pools and ponds

Look elsewhere if

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

Pros and cons

Pros

  • 3,300 GPH
  • Auto and manual
  • Check valve included

Cons

  • Leaves 2 in in auto
  • Import brand
  • Manual mode needs watching

Limitations to weigh

  • Manual pumps run only while switched on; stay with the pump so it doesn't run dry.
  • 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.
