Simple Pump Controller and Circuit

A recent project at work required that I drain water from two tanks periodically. Since both of the tank drains are located below the level of all the drains in the room, I would fill up buckets and transfer the water to the drains manually. Soon I realized that I could simply put a pump in the bucket to automatically pump the water to the drain whenever the tanks were drained. This is the story of how my brother and I accomplished this task.”
