Was following the video to winterize my Elite II. Followed all the steps, drained water tanks, turned off the gas, turned off water heater, adjusted by-pass valve, set the ball valves for winterization mode, cleared water out of faucets, everything up to attaching the hose to the inlet to pull in the antifreeze. I turned on the water pump and turned on the cold water in the kitchen sink. The hose pulled some of the antifreeze out of the container then no more movement. Some water was spurting out of the faucet but that was it. I finally turned off the pump because I didn't want to ruin it. Not sure what I am doing wrong but I am sure it was something I overlooked. How should the ball valve be oriented on the fresh water tank? Does it have anything to do with winterizing? Should there be a water source? I feel dumb for asking, it seemed pretty simple on the video. Any help is appreciated. Last thing, after winterizing I was planning on leaving the camper plugged. Should I turn off the inverter. I am planning on leaving the batteries (lithium) in the compartment in the camper and not doing anything with them. I live in North Alabama, temps dip to 19 or 20 degrees some nights. My camper is stored in a garage. Just adding that info in case it is helpful. Thanks for any assistance--Happy New Year!
