The operation of a sump pump is straightforward : 1. **Water collection:** Water enters the sump basin.2. **Level detection:** As the water level rises in the sump basin , it lifts a float attached to a switch.3. **Pump activation:** The float switch turns on the pump.4. **Water removal:** The impeller draws water and expels it.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 cycle repeats as needed, ensuring your basement stays dry.
