The most common reason a sump pump fails is a stuck or jammed float switch, often caused by debris or simple wear over time. When the float can't move freely, the pump won't activate or deactivate properly, leading to flooding or motor burnout. Regular cleaning and occasional replacement of the switch can prevent this issue.
