A sump pump is a relatively simple device that operates on a basic principle: : 1. **Water collection:** Water enters the sump basin.2. **Level detection:** As the water level rises in the pit, it lifts a float attached to a switch.3. **Pump activation:** When the water level reaches a certain point, the float switch activates, turning on the sump pump's motor. .4. **Water removal:** The pump's motor drives an impeller, which creates suction, drawing water into the pump and pushing it out through the discharge pipe. .5. **Water discharge:** Water is diverted away.6. **Pump deactivation:** Once the water level in the sump basin drops below a certain level, the float switch deactivates, turning off the pump.This automatic process ensures that excess water is effectively removed from your basement, preventing flooding and protecting your home from water damage. .
