The most common reason a sump pump fails is a stuck or jammed float switch, which prevents the pump from turning on when water rises. Over time, debris, mud, or mineral buildup can immobilize the float, leaving the pump inactive during heavy rain. Regular cleaning and testing can catch this easily, but many homeowners overlook it until water starts pooling in the basement.
