I still can't get hot water pressure when running shore water on my 2009 FDS. Starts off OK for 10 or 15 secs then reduces to a dribble. Both the cold in and hot out valves are open. The by pass connecting the hot with the cold lines is closed. Tank has been flushed out and is free of crud and deposits. Tank also fills. If there is some sort of blockage must be at some point where the water leaves the tank, because when I open the by pass, there is pressure, (but no actual hot water). Any one else experience this?
