Why Submersible Pumps Work Well in Flooded Basements

Step-by-Step: How to Use a Submersible Pump in a Flooded Basement

- Turn off electricity to the basement: Never enter a flooded area if power is still on. Switch off the circuit breaker connected to the basement to avoid electrocution.
- Assess the Water Depth and Damage: If the water is deeper than 2 inches, a submersible pump is the right tool. Also check for signs of contaminated water, structural cracks, or damaged insulation.
- Choose the Right Submersible Pump: Use a utility submersible pump that can handle debris and continuous operation. For heavy-duty flooding, look for pumps with a high gallons-per-hour (GPH) rating.
- Place the pump in the basement: Lower the pump into the deepest section of the basement floor. Make sure it’s fully submerged to prevent dry running. Use bricks or a sandbag base to keep it stable and prevent it from tipping.
- Attach the Discharge Hose: Connect a hose to the pump outlet and lead it outdoors – preferably downhill or into a storm drain. Avoid draining water near your foundation.
- Start Pumping: Plug the pump into a GFCI-protected outlet, or use a generator if the power is out. As the pump starts working, monitor the discharge hose to check that water is flowing freely.
- Monitor Water Levels: Keep an eye on the pump and adjust the hose or reposition the pump as water levels drop. For basements with multiple low spots, you may need to move the unit.
- Shut Down and Clean the Equipment: Once water is fully drained, unplug the pump, detach the hose, and wipe the pump clean. Allow it to dry thoroughly before storing.
- Begin Drying and Cleanup: Remove wet materials, sanitize the area, and run a LGR dehumidifier for several days to prevent mold. If insulation or drywall was soaked, begin structural drying and cleanup.
