Thank you, Esshup!
Being overly inquisitive I asked the same questions (except for the amount of air in the tank?) and it was just a guess as to it's exact location but Matt knew it's (or should be) within 5' of the well.
Jim's (trustee) comment: "if it's working, leave it alone!"
He also thinks everything I do out there is overkill, such as replacing the 12/2 romex tapped into the overhead triplex at the pond AND at the shop with 4g wiring (230v going to each), and also correcting the over-fused fuse box in the house, etc..
I'm thankful he lives out of town
