For year-round use, a lot of well houses in this area are actually well pits, with concrete block walls going down about 4-5 feet, and a removable roof on top.

Submersible pumps and bladder tanks in the basement/crawlspace have done away with a lot of well houses.

Like the construction detail....very nice!

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
