2016 Flagstaff 21FBRS Water Heater Bypass Valve

After searching for clear instructions to locate the water heater bypass valve to dewinterize my travel trailer, I didn't anything definitive and thought I'd post a few pictures to help the next person looking for the info.

The water heater tank is behind the black access panel you see on the outside of the camper. To access the tank, simply remove the two screws holding the protective panel to your right inside the storage compartment door.

The first picture shows the location of the water heater tank and bypass valves. The second photo show the valves in the bypass (winter) position. The last photo has the valves in the fill (summer) position so that water can enter the tank after the antifreeze has been flushed from the lines.
