position as shown below:
Fig 2. Float positions for a Fill application
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 Pumps-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 Pumps-Off float closes.
