I was winterizing (in Texas no less) and noticed a white plastic valve attached to a black housing. The housing is about 2" down, 6" deep and 3" wide. There is no marking on it, nothing to tell where is open, and when I move it, nothing comes out.
Can anyone please let me know what this is for and if it needs to be winterized.
We have a 2011 3001W Windjammer.
PS for some reason I cannot get a picture to attach. Try this link. I put the a couple of pictures there you can click on. Thanks again.
