why sump pumps fail 10

https://wiki-byte.win/index.php/Why_Sump_Pumps_Fail:_The_Most_Common_Causes_Homeowners_Overlook

Sump pumps often fail because of a stuck float switch, which can get tangled in debris or jammed against the pit wall. A power outage or tripped GFCI outlet is another common culprit, leaving the pump dead when you need it most. Clogged intake screens or discharge lines from mud, gravel, or roots force the motor to overwork until it burns out. Sometimes the pump simply cycles too frequently due to a high water table, wearing out the internal switch prematurely.
