Pawlowski is, again, correct.
The water on the pipe surface comes from the air.

How well sealed is "well sealed"?
Is it enough to buy the Home Chepot middle-grade stuff that comes with
taped edges that you push together?

My sense is that the adhesive tape is enough to keep it on the pipe but not
enough to make a real seal.
Is there stuff that is better to buy or should I cover the seam with
something like duct tape?

Thanks
