Why it matters
The CDU980E has a 3/4 HP motor in a cast iron and stainless steel body, rated at up to 5,490 GPH. Its vertical float fits narrow pits.
Top suction prevents air lock, so no weep hole is needed. Wayne assembles it in the USA and backs it with a five-year warranty.
Who it's for, and who should skip it
Good fit if
- High water tables
- Heavy storms and snowmelt
- Narrow pits
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
- 3/4 HP
- 5-year warranty
- Stainless and cast iron
Cons
- Price
- Overkill for light duty
- Can short-cycle 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.
