Pros
  • Keeps more than 50 gpm at 20 ft, so it copes with a tall basement lift
  • Cast iron motor housing and volute run cool and last
  • Piggyback float can be swapped or bypassed without pulling the pump
  • Sold by Amazon with a three year maker warranty
Cons
  • Tethered float needs a basin wide enough for it to swing freely
  • Draws 12 A, so it wants its own 15 A circuit
