- 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
- 25 ft quick connect cord reaches a control panel or outlet well away from the basin
- Has no float of its own, so it needs a separate switch or panel
- Draws 12 A, so it wants its own 15 A circuit
- Sold on Amazon by a third party for about the price of the automatic LE51A
