i haven't plumbed my garage yet but my local flaps that deals mostly in paint also told me of the 25' thing for moisture. can a person just run a 25' coil of copper or does it have to be a straight line pipe. i am a believer of copper my self but a buddy of mine is using truck airbrake line and seems to be working great for him.
