Rigid is not approved for underground as far as I know. Could be wrong
- but I'd be wanting the flexible myself.

Me too, our water supplier only accepts type K soft tubing.



Any ground shift will be accepted by the soft tubing, while hard drawn
"copper pipe" will be compromized. flexible copper pipe, and NOT in a
perfectly straight line, is best. Absorbs expansion and contraction
from temp changes without "growing" into the house or "shrinking"
away.
