Why it matters

The 5-MSP is a 1/6 HP manual utility pump in epoxy-coated die-cast aluminum with a thermally protected shaded pole motor. Little Giant rates it at 1,200 GPH and 26.3 ft shutoff.

It has a 1 in FNPT discharge with a garden hose adapter, a 10 ft cord and a removable screen, and weighs about 7.75 lb.

Who it's for, and who should skip it

Good fit if

  • Water transfer and recirculation
  • Small tanks
  • Repeat use

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

  • Cast aluminum
  • Compact
  • Known brand

Cons

  • Manual only
  • Modest flow

Limitations to weigh

  • Manual pumps run only while switched on; stay with the pump so it doesn't run dry.
  • A garden-hose outlet limits flow; use the larger discharge where the pump has one.
