Make sure that the rotation of the pump/motor is correct. In my area, nobody would use a well where the normal water level in the well with the pump off is 8 feet below grade. Usually the water is not good and may have a lot of ground water and possible bacteria in it. Looking at the motor in the picture, take a flash light and look into the motor at those slots at the front of the motor. start and stop the motor and as it slows down you can see the rotating armature inside. It should turn CW. If it is turning the wrong way it usually can be changed by removing the wiring cover and changing some wires. Check the instructions that came with the pump.
