I have an "06" 3055 and the water heater by pass valves are behind the panel in the storage bay next to the docking station. I took my screws out of the panel and it fits snug enough with out them so I now have fast easy entry. There you will find (3) 1/4 valves hooked to the water heater tank plumbing. To bypass the heater turn the center valve 1/4 turn to open that line. Turn the top and bottom valves 1/4 turn to close those valve. Now the hot water will circulate and bypass the heater tank. Hope thats clear. It will become second nature soon. Of course your tank could be in another location, if so you will just have to look around for it.
