Here are a number of prior responses to similar questions about PRV's, water heaters, and expansion tanks - and yes, by code and common sense you need an expansion tank in the cold water line between the water heater and the first possible flow control device in the line - backflow preventer or pressure reducing valve, because without that when the water (and especially any air in the water heater) heats up and expands, without the expansion tank to take up the expansion you can overpressure the lines in the house and the tank - and the weakest point will fail eventually.

There are more links to the same issue beneath each of those, at least if you are logged in as a registered user (not necessary to be a member to see those).
