Found Well in Backyard -- How to install pump?
I would recommend that you call a local &quot;well guy&quot; and ask him the same questions. They have the expertise to do everything &quot;well&quot; related including determining if that pipe or casing is really for an old well. If it is a well, he may have even been the guy that drilled the original well or knows who drilled it to get the specs of that hole in the ground.
