[Shop-talk] Airline Piping

[Apache]

I am planning to install an airline system in my garage in a few weeks.

A while back it was suggested to run the horizontal loop of the system up in 
the roof trusses.  I like this idea because it cleans up the clutter and 
allows for easy fixturing to the trusses to get proper slopes for water 
drainage.

Does anyone have any comments on how this would work in the winter where the 
temperature will mostly / always be below freezing?  I have a drywalled 
ceiling, so it will stay cold in the roof trusses.  Since the moisture in 
the air is less in the winter is this an area of concern?

Thanks in advance,
