Sump pumps usually fail because of clogged intake screens, jammed float switches, or burnt-out motors from constant cycling. Debris like gravel or lint blocks water entry, while a stuck float leaves the pump running dry, overheating and destroying the impeller. Power outages during storms also leave basements flooded. Regular cleaning and testing can catch these issues early, but neglect turns a minor problem into a soaked mess.
