While connected to city water we are still running off the fresh water tank, almost ran empty. Was not told of a valve to change over am I missing something? This is our first rv and first trip!
Make and model will help get answers. I would say most, if not all, motorhomes will have valves in the wet compartment to control flow of fresh water. Typically, one would close valve to onboard water tank and this now opens city water connection to flow water into camper.
