The water heater is either normal, or bypassed for winterizing. It works regardless of city water or internal tanks. From your picture it looks like you have the water fill (the internal tanks) on thus causing the eventual overflow, and I can't tell for sure but it looks like maybe the water heater anode is not installed. If the previous owner had winterized, he may have forgot to install a new anode. Get one, teflon, 1.25" socket, done.
