Witching rods... don’t ask me, but they do work. Metal detectors as electrically piped wells are often piped or will contain a collar for the hose at the top. Look for a flat piece of ground that might have contained the original home or barn. They often dug the well first back in the day before they built the house next to it.
Best of luck. A well is a wonderful thing!
“Witching” or “divining” rods do work - for some people.
And the funny thing is, in my experience, only those who can do it believe that it works.
Anecdotally I believe it’s a genetic thing, having to do with our “conductivity”.
My dad could do it, my mom could not.
I can do it, my kids can do it, my wife cannot.
My sister can, her husband can’t, her kids can.
