It was probably caused by not drying all the way... thats why you would get lines of rust inside, and as for the purge valve, very little people clean it let alone dry it off... lol
the purge valve needs to get cleaned out well too or else the BB will rust again and freeze up. remember rust is not patina, once you get a spot of rust it is basically impossible to stop it, the only real way is to remove ALL the rust, every last little molecule of it
