I was searching for explanation for my high electric use and found that my well is likely running more than it should. I pulled the cap to see if I could see the pitless adapter leaking. This well has a vented cap but the PO had it sealed and some bubble wrap shoved in the 1st few feet of the casing. I removed the bubble wrap and put the cap back on and the well blows air just like this: I shut the well off last night and this morning the gauge was 0. So this well is a weird setup where the pressure tank (spun fiberglass) is buried outside. I'm thinking this was done because the PO had the well drilled about 5 years before he built the house. Maybe an alternative to building a well house? So at some point they ran the switch and gauge (with 3/8") hose under the house. Here is a diagram of my set up My thoughts are to dig the pressure tank and pitless adapter up today and see how all this is ran and see if there's a leak in this hose system which I think there might be as the hose and switch power are ran inside a 2" pic and there is water in the pvc.
