I have made several attempts to fill my fresh water tank with no success. I am following the instructions in my Reflection owner's manual and the picture posted on the door inside the basement. Still no luck, I can't figure out what I am doing wrong. After setting the valves to match the picture, I turn the city water supply on at the hydrant and immediately water flows out the overflow behind the trailer axles on the drivers side.

Please let me know what I am doing wrong or direct me to better instructions online. Thanks
