Cardinal 34QS winterizing

Hi Everyone, new fifthwheel to me, 2008. we've owned a fifthwheel for many years and done the winterizing myself. but this camper is new to us this year and winterizing for the first time. just have a question about the fresh water tank. if i run the pump to push all the water out of that holding tank, then use the pump to draw in the Anti freeze, would the AF make its way to the holding tank? doesnt seem like it would, but need to be sure. thanks -- Brian

Use the fresh water drain to drain it, not the water pump. There is probably a valve in the line between the fresh water tank and the pump. This line is the suction side of the pump. Turn that valve so the pump no longer sucks from the fresh water tank. It should then suck from a short hose that you can insert into a jug of antifreeze.
