Best Sump Pumps for Your Home
Sump pumps can save you thousands of dollars in flood damage. They are ideal for parts of the country that experience heavy rain and for houses built on flat or low-lying areas.
Tip: Choose corrosion-free housing materials, consider water capacity and know the height water has to be lifted for removal.
A sump pump consists of six main components:
- Ground Water Collection System: This routes excessive groundwater to a sump basin.
- Sump Basin: This collects liquid for removal.
- Primary Sump Pump: 1/4-horsepower to 1-horsepower, submersible or pedestal variety.
- Discharge Pipe/Hose: The open valve or pipe run carries discharge water away from home.
- Check Valve: This prevents backflow through discharge outlet.
- Backup Sump Pump System (Optional): This provides added protection in case of a power failure or if primary pump fails.
Consult the chart below for information regarding the two types of primary sump pumps.
If your home has been affected by flooding or other water damage, you can find remediation and restoration tools and equipment at The Home Depot Tool Rental Center. Rent submersible pumps, dehumidifiers and other equipment to help get your home back to normal.
pedestal or column pumps

battery back-up sump systems
|Feature/Benefits||Motor is mounted on shaft and is outside of the sump basin. The vertical float design is adjustable for specified on/off points. Ideal for smaller sump pits (10" or less).||Motor is sealed within the sump basin and unit is installed below water level.||Automatically begins pumping during power outages, when the main pump fails or when water flow exceeds the capacity of the main pump.|
|Other Considerations||Economical. Should be positioned where motor cannot be submerged. Exposed motor can make repairs easier.||Quiet and less obtrusive. Safer if children are in the house as motor is not above basin. Ideal for finished basement. Provides a cleaner and less obtrusive look.||Easily installed in either a normal sized or narrow sump pit.|
Switches turn the pump on and off and there are many different types:
- Capacitive switches use a microprocessor to measure water level and engage the pump when the water level reaches a preset point in the sump basin.
- Vertical switches are a mechanical device that automatically turns a pump on and off when water reaches a preset level.
- Diaphragm switches are a mechanical device that uses water pressure levels to turn a pump on and off.
- Always read owner’s manual before installing.
- Consult an electrician for rewiring.
- Research local code requirements for water discharge.
- Always disconnect power prior to working on sump pump.
- Install on a dedicated GFCI protected outlet.
- Never use extension cords with pump.
- SSPMA Standards. Look for a pump that conforms to the standards of The Sump and Sewage Pump Manufacturers Association.
- Water-Powered Pumps. Uses city water pressure to pump water. Not designed to handle large quantities of water.
- Corrosion-Resistant Construction. Enables pumps to withstand the rigors of long-term use.
