We have no water and cannot get the pump to turn on... it just quit like that!! We have no blown fuse, nothing tripped... what could it be? Is there a reset switch or could our bladder tank be low on air? HELP

Use a tester to check for power entering the motor.

Is the pump above ground or in the well?

First check to be sure you are getting power to the switch, and then check for power to the pump. You'll have a black and white going to the switch, and a black and white going to the pump from the switch. Make sure the switch points are engaged when checking for power to the pump.

Some switches do have a reset lever on the side, but I think you would have already noticed it and tried it, so I am guessing yours does not have one. Most do not.

This video is pretty good to watch. https://www.youtube.com/watch?v=_ggoyio1hWc
