Connect the city water to it and see what happens.

5) you have a stuck or clogged check valve near the water heater.
How many water heater winterize valves do you have?
IF you have 3 valves, you probably don't have a check valve.
If you have only 1 or 2 valves you most likely do have a check valve.
We had a poster here recently who found a broken check valve and
he was also getting no hot water.
