Step-by-Step Guide to Installation

By now, you’re probably eager to learn how to install a sump pump in the basement. We’ve got you covered with a step-by-step breakdown.

Digging the Sump Pit

Dig a hole where your sump basin will sit. This pit must usually be around 24 to 30 inches deep and about 18 inches long. The dimensions may vary depending on your pump’s specifications, so read the manual carefully.

Installing the Sump Liner

Next, place your sump basin in the hole and surround it with gravel for better drainage. Once firmly in place, pour some cement around the rim to lock it in position. 

Assembling the Sump Pump

Follow the manufacturer’s guide to assemble your sump pump. Although most come pre-assembled, you may need to attach some components like the float switch, impeller, or even the check valve.

Connecting the Discharge Pipe

Fit a PVC pipe into the pump’s discharge outlet. Use Teflon tape to make a watertight connection. Ensure the pipe directs water well away from your home’s foundation—about 20 to 30 feet is a good rule of thumb.

Electrical Wiring

Wire the sump pump to a GFCI outlet. This is critical for safety. If you’re uncomfortable dealing with electrical components, consult an electrician.


Before declaring victory, test your installation. Fill the sump pit with water and check if the pump activates and effectively discharges the water away from the basement.

Common Mistakes and How to Avoid Them

  • Wrong Size: Ensure the sump pump is appropriately sized for your basement’s dimensions and water issues.
  • Poor Location: Avoid areas near electrical outlets or flammable materials.
  • Incorrect Slope: The discharge pipe should slope away from the house for effective water removal.

Maintenance Tips

Sump pumps aren’t “set and forget” devices. Regular checks can save you a lot of headaches down the line.

  • Run a quick check every month.
  • Remove any debris from the pump’s screen or inlet opening.
  • Inspect the outlet and discharge pipe for blockages.
  • Replace the backup battery every 2-3 years.
  • Perform a full system test before the rainy season.
