Rapid cycling from a failing pressure tank
When the bladder tank loses its charge, the pump snaps on and off every few seconds instead of resting between draws. That rapid cycling is what actually destroys submersible systems here. It burns the control-box contacts first, then works its way into the motor windings. The pump gets blamed, but the tank started it. This is why we always check the tank and switch before we ever talk about pulling a pump.
