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 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:** The discharge pipe carries the water away from your home's foundation, usually to a designated drainage area like a dry well, storm drain, or a safe distance from your property. .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. .
