Stan: I seem to recall "stainless" not being very magnetic.....some water
well pumps have plastic housings tho.......I had the pump out three or four
years ago for an overhaul so I am aware of what is in the ground in my
circumstance....
I have plastic pipe to the pump and a fiberglass tank, but my house plumbing
is copper, so I would likely have to drain the lines to prevent ionic
conduction interaction......
I know it sounds a bit whacky, hi....
Perhaps safer to just lower a separate transducer down the hole, but that
brings up potential bio contamination issues....
