Cliff - I just reread the link you provided on the drain hose and the 100 page Service Manual and the Owners Manual on the Norcold 1210 and while it was a quick read - I didn't see any manufacturers reference or instruction on water being necessary in the cup.
On the linked thread - RV Wizard indicted..
"The weight of the water in the drip tray will push water out through the end of the drain tube which should be placed in a collection tray mounted top left of the burner area. Once the water is drained out, a small amount of water should remain in the tube to create a vapor barrier and not allow warm air back into the fresh food section. Good luck and keep us posted."
This seems to suggest the moisture on the end of my tube is sufficient to create the vapor lock. Wizards wording is a little confusing to me as I don't know how to interpret which way the water is flowing from water pressure in the cup. I'm thinking back into the fridge. I didn't see a pump inline with the drip tube - so if gravity only - water has to overcome the water pressure in the cup.
I'm thinking the snorkel has no effect on the cooling or water in the box - and that a plugged line is the real culprit. If it can't get out of the tube - for any reason - it has to go somewhere.
If you have manufacturers info please share. I'd like to read the actual theory.
I went down this road before a tech actually said - here - slip this over the drip tube and out the side vent. And we looked around and saw them everywhere...
Edit - I'm so confused... two posts - similar topic - and I thought this one was lost on the eithernet... so I rewrote it on another thread.. oh well - snorkel works for me. The other post is more accurate...
