Why it matters

The 92372 is a 1/3 HP thermoplastic sump pump with a vertical float switch. Superior rates it at up to 2,880 GPH and 25 ft of lift.

It has a 1-1/2 in NPT discharge, a 10 ft cord and a one-year limited warranty.

Who it's for, and who should skip it

Good fit if

  • Light-duty pits
  • Tight budgets
  • Spare pumps

Look elsewhere if

  • Sewage or toilet waste
  • Draining pools or floors (a utility pump is cheaper)
  • Homes that need a backup but have only one pump

Pros and cons

Pros

  • Low price
  • Vertical float
  • Light

Cons

  • Plastic
  • One-year warranty
  • Shorter life than cast iron

Limitations to weigh

  • 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.
  • Fit a check valve on the discharge so water in the pipe doesn't fall back into the pit after each cycle.
