I have an 07 Sedona. Does anyone know how to set the valves to make the fill hose go directly to the water lines instead of to the tank first? I can get it to fill the tank but I want to be able to draw from the gallon of antifreeze directly into the system. Last year I didn't get it well enough and now have a broken valve on the toilet. Hoping someone here knows or has an e-mail to G-Stream. Thanks in advance.
