Wayne CDU1000
#2 in 1/2 HP and upFull review
For a basement with a very high water table or a long, high discharge run. Most homes will be better served by a 1/2 HP pump.
Amazon $254.99$254.99
3.6/5
For a wet or deep basement on a budget: it pumps as much as pumps costing twice as much.

Pros
- About 3,800 gallons an hour at 10 ft for well under $200
- Still moves about 2,000 gallons an hour at 20 ft, enough for a deep basement
- Top suction intake resists clogging from pit debris
- Light at 22 lb, so easy to lift out for cleaning
Cons
- Steel motor housing is less durable than cast iron in a pit that stays wet
- Only a 3 year warranty
- Short 8 ft cord
