Hi I have Freedom Elite 22FE, same floorplan. Next time you are in the coach. Below the pantry is a panel with 4 or 6 screws. Remove that panel and you should find the water tank, pump, tank drain, and low point drains. The low point drains might be covered by foam that is oversprayed from Thor trying to make the water pump quieter. I found this by looking under the coach on the right side and finding the large white pipe that drains the water tank.
My water fill is located to the right of the dinette window if yours is there also then this should help. They do change these coaches all the time, but I am betting it is there.
My coach does not have the outside spigot near the wheel well. If you have that you can drain that way, but behind the panel will be the water pump and low point drains.
