A sump pump is a relatively simple device that operates on a basic principle: : 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 triggers a float 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:** 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. .
