I inspected a garage under a home yesterday that contained the main electrical panel. When I opened it there was water standing in the bottom of the panel. Although the water was clear, a small amount of rust had accumulated on the surface, leaving the impression the water had been there for some time. The water was approximately a half-inch deep.
There are no water sources (pipes, etc) above the panel. The service line to the panel appears dry, and there are no stains present that would indicate where the water entered. Has anyone seen anything like this?
I doubt a dangereous prank was played because the home was vacant for some time and an old woman lived there when it was occupied.
