Reverse osmosis tubing code

[rural_engineer]

Are there any rules governing how you can run tubing from a reverse osmosis system that I should be aware of? In particular, rules about running it overhead in a heated crawlspace?

Thanks!

Don't think there is any code issue, but do pay attention to the type of tubing you use. RO sourced water can leech metals from the wrong tubing.
