Why it matters
The 253 is a 1/3 HP pump in Liberty's 250 Series: a one-piece UniBody cast iron housing with an epoxy powder coat and a vortex impeller. Liberty lists it for sump and effluent duty.
Its bearings are permanently sealed and lubricated, and the quick-connect cord can be replaced without opening the motor. It has a 1-1/2 in discharge and a two-year warranty.
Who it's for, and who should skip it
Good fit if
- Average basements
- Effluent duty
- Owners who want serviceability
Look elsewhere if
- Sewage or toilet waste
- Draining pools or floors (a utility pump is cheaper)
- Homes that need a backup but have only one pump
Pros and cons
Pros
- UniBody cast iron
- Quick-connect cord
- Sump and effluent rated
Cons
- Price
- 2-year warranty
- Float needs pit room
Limitations to weigh
- Maximum head is where flow drops to zero; at your lift the pump moves less than its maximum flow. Size it with the sizing calculator.
- Fit a check valve on the discharge so water in the pipe doesn't fall back into the pit after each cycle.
