Why it matters

Superior rates the 93501 at up to 4,800 GPH and 25 ft of vertical lift from a 1/2 HP motor in a cast iron body. A tethered float switch runs it automatically, and the 2 in NPT discharge passes 2 in solids through a non-clogging vortex impeller.

It has a 10 ft cord and a one-year limited warranty.

Who it's for, and who should skip it

Good fit if

  • Budget replacements
  • Basement bathrooms
  • Wider basins

Look elsewhere if

  • Clean-water sump pits (a sump pump is cheaper)
  • Septic tanks unless the maker allows it
  • DIY installs where code requires a plumber

Pros and cons

Pros

  • 2 in solids
  • 25 ft lift
  • Low price

Cons

  • One-year warranty
  • Tether needs room
  • Professional install usually

Limitations to weigh

  • Sewage pumps need a sealed, vented basin, usually 18 in or wider; size the basin to the pump's switch range.
  • Sewage and grinder installations usually need a licensed plumber and a sealed, vented basin to meet code.
