So, I believe when the dealership did my winterization, they screwed up my coach (i.e. my icemaker is leaking water onto the floor and seeping out). Also, when I did my season shake down, I hooked up to city water and water poured out my low point drain points. Which ones are supposed to have drain plugs on them? Obviously, as covered before in another thread, the screened one doesn't. That leaves four others. As seen in the pics, I have two blue ones clustered together and then a red and a blue with the screened one. Which are which and are they all supposed to have drain plugs? I'm just trying to figure out in my head (which is part of the problem) that there's tank drains and city drains? I'm confused.. :-)
