The Final Chapter
As per suggestion here, I called Delta at the number listed on my water purifier manual. Talked to a nice young man who seemed to understand my problem of the missing "washer" and said, "we'll send you a new hose." Well, I'll be. Today I received the new hose and on looking inside I can see all the parts where they belong.
I had previously called a large Airstream parts dealer who said they had the hose, but the price with shipping was about $95.00. I will say when I later informed them that I was getting one from Delta for nothing, that they said that was wonderful. (I think so too).
To all of you who helped out and provided input, thank you very much!! We beat around the problem a little, but solved it in the end and that's what the forums are about.
Keep the shiny side up. Travel safe.
