I have a valve to turn water heater to bypass or normal operation. A second balve that I turn to winterization that allows the antifreeze to flow from the bottle. They are both in a back compartmnet and clearly marked. Are there other valves I should turn. I have done this before and never had a problem. It is only two years old. Winterized twice as I got in the fall two years ago. So this would be number three. The settings for city or tank shouldn’t matter and all other settings are drains. They have made it seem pretty simple with all marked clearly or at least I thought.
Sounds like you have the 1-valve system, and the only cause I can think of is a stuck check valve at the output of the water heater. You could try tapping on it or just replace it.
