Yes your Check valve on the exit or TOP out let of the water tank is bad. I changed mine in November for the same thing It take a 1" wrench and a long arm to get to it. You will have to take a few furnace heater hoses off to get to it. The upper hose connection is for winterizing along with the upper and middle valves. City water is for using the city water at a camp ground the same valve also fill the fresh water tank when using the lower valve.
