OK so now I have solved the complete mystery. At least why the valve was leaking. The fitting that connects the hose to the pump seemd like it was very wobbly and it was bottomed out as far as tightness goes, Almost like something was missing. The dealer is the only one who has done anything to this TT. They winterized it last year as well. I noticed one of those washers on the other side of the pump. Its one of those washers that is flat on one side and mounded on the other. So now things are adding up. Why that was there I have no idea, but I know it was there since I started the whole process. Otherwise I would not have had this issue. So my thought is the dealer removed this washer for some strange reason, perhaps in the event I didnt bring it to them to winterize I would have issues. IDK. However I wont be going back to that dealer again.
Not related to this I had it in there for some warranty work when they winterized it. The hot water heater would make a banging sound when it ignited, one of the speakers never worked from day one and my black water flush valve would not accept water. I assume the hot water heater and black water are fixed, but they never did fix the speaker. I couldnt try any of this when I left because it was all closed up and winterized. Hopefully those main issues did get repaired.
I know this is a long winded story, but it felt good venting.
Thanks again to all for the insight, it is very much appreciated.
