Why it matters

Prostormer rates this 1 HP pump at up to 3,700 GPH and 26 ft of lift. Its float switch runs it automatically, or can be locked up for continuous running when the water is shallow.

Three outlet sizes (1, 1-1/4 and 1-1/2 in) suit different hoses. Prostormer says to hold it underwater at an angle for 20 to 30 seconds at first start to clear trapped air.

Who it's for, and who should skip it

Good fit if

  • Draining pools
  • Flooded areas
  • Temporary pit use

Look elsewhere if

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

Pros and cons

Pros

  • Float switch
  • Three outlet sizes
  • Low price

Cons

  • Air lock at start
  • Locked float can run dry
  • Import brand

Limitations to weigh

  • Don't let it run dry; most pumps wear out quickly without water to cool them.
  • Rated flow is at little or no lift; through a garden hose or up a stairwell, expect much less.
