Well, no I didn't. There are no visible or operational signs that things aren't working as expected, but I just looked it up and it's pretty easy to do. I'll check it out soon. Thanks for the reminder!
around here generally city water systems do not have an expansion tank. On a well system the tank is an "accumulator" to hold water pressure so the pump doesn't come on every time you get a cup of water

If it has a pressure regulator...... Some places require check valves to prevent contaminated water supply pipes when the supply has to be shut down.

The expansion tank was required when I replaced my water heater several years ago. There wasn't one on the previous system, so I guess it was added to the code more recently.
Must have an anti-syphon or backflow prevention valve in the waterline if it needs an expansion tank
Possible disguised as a pressure regulator.
