Just a few thing you should know about well and the type of wells. You can push water further than you can pump it.
A shallow well will only draw water for about 26 feet. A jet pump puts half the water back down the well to push the water up. You cannot compress water. The air in the take is what give you the differential in water pressure in the tank using pressure switch, on-off Hi-low. I hope this helps.

Just remembered this. Did you ever find the issue, and do I need to concede the win to Savell? G.

seems to have healed itself.
