Hello Tony, If the rings were in the up position I would imagine that the water would drain out. I have never tried to pull up real hard because I felt that if I did I would be having to replace them if I broke them. Anyway's I winterize with the attachment that goes on the water pump that siphons the antifreeze right out of the bottle. Neat little contraception for only around $15.00. No need to contaminate your fresh water tank with the pink stuff.
How have you been? So you store the RV in the winter. I keep mine going all year and just keep it off of the roads if its snowing. I just make sure that I keep the bottom real clean .Just turned 20,000 and its running like a top.
