Hmm that is weird. Only time I had the tubing slide off like you are saying is after months and months or when I tried to move tubing when switching dome sizes. It could be A. the end of the tubing is stretched to where it doesn't grip onto the dome well enough, in that case cut a little off then put it on again to ensure it has a nice tight grip on there. B. the part on the dome that the tubing goes onto may not be shaped right? Look at it to see if it's different from your other dome if you have a 2nd one. In that case it was just a manufacturing mistake, then contact Lucy and tell her the issue.
