This is long overdue, but I got some time to really address this leak problem today.

I cleaned the area around the fitting on the bottom of the tank. Got most of the old solder off of it with a wire wheel on my drill motor. Then, I resoldered the fitting with a propane torch. Got a really nice seal around the fitting.

I think I found the real culprit: a really fine, hairline crack in the tank coming from the area around the fitting.

I will try coating the inside of the tank as suggested before.

Think that will do the trick?
