If there is a PRV on the system you must have an expansion tank.

pressure

The pressure should build up in the entire system, not just the hot water, unless there is also a check valve on the line to the water heater.

You are a plumber and you dont know you need an expansion tank after a PRV?

I'm sure you could have done some more trouble shooting before asking here!
