Why this DeWalt sump pump stands out
-
Stainless steel advantage: A corrosion-resistant housing means longer service life in damp sump pits, reducing maintenance and replacement costs.

Automatic reliability: The vertical float switch activates and stops the pump based on water level, so you don’t have to monitor it constantly—even during heavy rain or power outages (with a suitable backup if needed).
-
Powerful yet efficient: 1/3 HP delivers robust pumping performance (up to 4500 GPH) for fast water removal, while the 25 ft maximum head covers multi-level drainage scenarios.
-
Solid construction, simple setup: Bottom suction intake helps keep debris out of the impeller, and a 2" discharge fits standard hoses and drainage setups for quick installation.
-
Long-term assurance: A 10-year warranty and CSA compliance provide added peace of mind for residential and light commercial use.
Ideal use cases
- Basement and crawlspace flood prevention and response, especially during heavy rain or rapid snowmelt.
- Utility rooms, sump pits, and garages where quick water removal is essential to prevent damage to belongings and flooring.
- Construction sites or workshops that require reliable drainage from temporary sumps.
- Areas prone to intermittent standing water that benefit from automatic, hands-off operation.
Practical setup and operation tips
- Place the pump securely in the sump pit with the float arm unobstructed so it can rise freely as water level changes.
- Connect the 2" discharge outlet to a drain line or hose, ensuring it runs to a safe discharge area and won’t backflow into the pit.
- Plug into a dedicated 120V outlet. If you expect prolonged flooding, consider a secondary backup method or sump pump with a battery backup.
- Keep the bottom suction intake clean and free of debris to maintain optimal flow and prevent clogs.
- Regularly inspect the cord, housing, and switch for signs of wear, and perform routine maintenance to extend the pump’s life.
The DeWalt 1/3 HP submersible sump pump combines rugged stainless steel construction with an intelligent vertical float switch to deliver hands-off, reliable water management where you need it most.
