Unplug the sump pump from the power outlet.
Plug the sump pump power cord into an available outlet on the backup generator.
Position the generator in an area where it is away from water or off the ground. Use an extension cord, if needed, to run from the sump pump to the generator, making sure the cord is not submerged in water.
Turn on the generator. As the water level rises in the sump pump pit, the sump pump should draw power from the generator.
Verify the pump switch is in the "On" position.
Things You Will Need
- Back up generator (with 500 to 1200 wattage power)
