Who it's for, and who should skip it
Good fit if
- Very wet basements
- High water tables
- Budget 1 HP
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
- Dry basements
Pros and cons
Pros
- 1 HP
- 1/2 in solids
- Low price for 1 HP
Cons
- 3-year warranty
- Overkill for most
- Short-cycles in small pits
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.
- Use the sizing calculator with your lift and pipe run before choosing horsepower; bigger isn't better if it short-cycles.
