Why it matters

This Green Expert pump wraps a 1 HP oil-free motor in a 304 stainless steel body and base. Green Expert rates it at up to 4,000 GPH and 32 ft of lift.

Its 6 in cylindrical body and top discharge make it easy to drop into narrow pits and wells. It includes barbed, NPT and garden hose adapters and a lifting rope.

Who it's for, and who should skip it

Good fit if

  • Narrow pits
  • Emergency drainage
  • Owners who want metal

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

  • Stainless body
  • Slim 6 in body
  • Oil-free motor

Cons

  • Manual only
  • Price
  • One-year warranty

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.
