Why it matters
The LE51A is Liberty's 1/2 HP automatic sewage ejector: heavy cast iron, an oil-filled motor with thermal protection, permanently lubricated ball bearings and stainless steel fasteners and shaft.
Its quick-connect 10 ft cord can be replaced without opening the motor. It discharges through a 2 in connection and carries a two-year warranty.
Who it's for, and who should skip it
Good fit if
- Basement bathrooms
- Owners who want serviceability
- Liberty systems
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
- Quick-connect cord
- Ball bearings
- Cast iron
Cons
- Price
- Needs a sealed basin
- 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.
- Fit a check valve on the discharge so water in the pipe doesn't fall back into the pit after each cycle.
