Overview
Swapping out a tired basement sump pump, the Liberty cast iron unit drops into pits as small as ten inches and runs automatically on a magnetic vertical float. Its discharge size matches most existing plumbing.
A one-piece cast housing with no lower motor seal improves durability, and the vertical float suits narrow pits. The quick-disconnect cord makes replacement easy. Warranty is listed as two and three years in different places.
Who it's for
Homeowners replacing a standard sump pump suit the drop-in fit. A power outage backup needs a separate battery system.
Pros and cons
- Automatic vertical float
- Fits narrow pits
- Cast iron durability
- Stainless shaft and fasteners
- Warranty length conflicts
- Power source spec is wrong
Performance notes
Flow drops as lift height increases, so vertical run to the outlet decides real output. The float switches on with rising water. The sealed motor is thermally protected against overheating.
