.... and you hear water gurgling there also?
Yes I can hear it.
I don't know if it is really a problem as long as it is not freezing weather. In freezing weather the line could freeze shut.
That is a major issue for my location. I want to run one of them through the winter and a frozen line will definitely be an issue.
Why not put a tee into the lowest point on your 1" line and add a ball valve which you can open to bleed off accumulated moisture whenever you want?
I thought of this and it's easy enough to do now but it isn't going to help in the winter when the drain freezes.
