Tap a step to watch it again.

  1. Make sure the pump is plugged into a working outlet and nothing is piled around the pit.

    Don't reach into the pit while the pump is plugged in.

  2. Slowly pour a bucket of water into the pit until the float rises.

  3. The pump should switch on, empty the pit quickly, and switch itself off.

  4. Outside, find where the discharge pipe ends. It should be clear, and point away from the house.
