The operation of a sump pump is straightforward : 1. **Water collection:** Water seeps into your basement or crawlspace through the foundation walls or floor. .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 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.
