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 triggers a float switch.3. **Pump activation:** The float switch turns on the pump.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:** The system stops operating once the water is removed.This automatic process ensures that excess water is effectively removed from your basement, preventing flooding and protecting your home from water damage. .
