Jeff...if there is a check valve between the water heater and the pressure tank the problem would not be the pressure tank would it? Researching the internet I found a couple articles on installing water heaters on boats and two of them recommend the check valve just before the cold water input to the tank to prevent hot water migration back to the pump but not sure that is a problem.
