Honestly, I don't know, I'm not a plumber. There are a couple possibilities, including that it was built into the water heater or the relief valve did it's thing. Some water heaters don't need expansion tanks at all, either. It's generally a "just in case" thing, since the right failures in the wrong way could lead to a hot water bomb going off in your house.
