I was looking at running copper in my garage a while back and couldn't remember why I didn't... Maybe work hardening - from the vibration in the compressor or something... not sure. Ended up using black pipe instead.
no just reg old pex water line from hardware store . . . no fancy kits.
I couldn't believe it my self and it showed 150psi max on the line he was using .
