My guess would be that there was a whole house filter there due to the bonding wire… In any case there is a problrm there. Black pipe should never be used on water lines, they should only be used on gas lines. If that pipe had ever been used as a gas pipe it would be contaminated with gas which is not something that people should be consuming.

Jason is quite correct that black pipe should not be used for potable water for the reason stated.
Perhaps this was a DO-IT-YOURSELF MAGNETIC WATER TREATMENT. The black pipe gives you an iron core. Now you just have to put some windings around it. It won't do much in the way of removing iron from the water but it is a popular beleif.
