A pump that runs constantly, one that will not run at all, or one that is simply old enough to be the suspect.
Most homes on a private well run a submersible pump sitting down in the casing, though some shallower or older setups use a jet pump at the surface instead. Either way, when the water stops or the pressure goes wrong, the pump is the first thing everyone suspects, and it is frequently the last thing that actually needs replacing.
Before a submersible pump comes out of the ground, the fault gets narrowed down from the surface: pressure at the tank, behavior of the switch, the wiring and the breaker, and whether the symptom is a slow decline or a sudden stop. A pump that has genuinely failed gets replaced properly, sized to the well and the household. A pump that has been blamed for someone else's failure gets left alone.
Describe the symptom and we will get you matched with a well or pump contractor who can actually look at it.
