The first pic shows a piece of 3/4 rigid. If you look closely you'll see a white wire on one end that I was trying to get out of the pipe. I wanted to use the pipe again so I sawed it off right in the middle of a coupling. Imagine my surprise when I still couldn't pull it out. The 2nd picture shows why, ice had pushed the neutral wire thru the crack in the pipe. No one ever noticed it as you can see by the paint on the wire. I think its quite likely the conduit was carrying the current for the device the neutral was hooked to. It happened to be a 2" solenoid valve on a gas tank. oops
