Thanks, Cheryl. Yes, that manual in progress is a good one. I think the confusion began when our dealer re winterized for us when we told him we weren't planning on going out immediately (only had a week). He replied that he put RV anti-freeze in the lines to the Alde. Perhaps, he didn't know that the valve would have shut that off. Well, we think the black valve will do that. Secondly, the manual sent to is was for the wrong system! I think we just need to nip it and use it, come what may. Have you winterized?
