Thanks for the replies...especially Solo for taking the time. I am also referring to a 2011 Itasca Ellipse 42QD. Yes I am referring to the lines behind the exterior access panel. I've reread the instructions again and I don't see where it says to disconnect the line from the icemaker to the valve. Step 1 says shut off water supply in the galley...I get that. Then it says to disconnect the water supply. If you have already shut off the supply line why do you need to disconnect it at the Winterization valve? How can you flush the supply line with antifreeze if you shut off the supply line back in step #1? Could you explain the valve positions? Which lines are active or open when valve is ON and which are active or open when valve is CLOSED? I appreciate your patience, experience and knowledge.
