Overview
The Wayne CDU980E is a 3/4 HP submersible sump pump with cast iron and stainless steel construction, rated to move up to 5490 gallons per hour and backed by a 5 year warranty.
Its top suction, anti-airlock design is meant to reduce clogging without the weep hole many sump pumps need drilled into the discharge pipe, and Wayne markets it as running quietly for a pump in this output class. At 3/4 HP and 5490 GPH it sits toward the higher-capacity end for a residential basement pump, useful for heavy storm inflow rather than light-duty drainage.
- 3/4 HP motor, 5490 GPH
- Cast iron and stainless steel housing
- Integrated vertical float switch
- 5 year warranty, USA assembled
Who it's for
Suits homeowners dealing with a high water table or heavy storm inflow who want more capacity than an entry-level 1/3 HP unit, and who prefer cast iron and stainless steel over plastic.
Strengths and trade-offs
Drawn from this product's published specifications.
- 5490 GPH output suits heavy storm inflow
- Cast iron and stainless steel construction
- Top suction design avoids drilling a weep hole
- 5 year warranty, assembled in the USA
- Higher capacity and cost than needed for light-duty pits
Performance notes
The vertical float switch is built into the pump body so it can still fit a narrow sump pit without a separate float arm needing clearance. The top suction inlet is designed to resist airlock, which Wayne states removes the need to drill a weep hole during installation, a step many competing pumps require.
