In this case, the pumps are attempting to keep the well full. When the well is full, all three floats are closed. If the level drops below the Lead float, then the first pump will turn on. If the level rises above the All-Off float then the pump will turn off. If the level continues to fall below the Lag float, then the 2nd pump will turn on. Both pumps will remain on until the All-Off float closes.
