As I understand it, code allows soft copper to be run inside a wall cavity for water lines. I am installing a long a 24' run of 3/4" hot and cold lines to a bathroom remodel. The lines need to travel from a crawl space, then inside a preexisting exterior wall and finally through a brick wall into the bathroom space. The lines need to make one 90º bend inside the preexisting wall. I would rather not notch an entire wall of studs and instead prefer to auger holes for the pipe. Rigid pipe will be difficult to maneuver (but maybe not impossible in a couple of 10' joints). While the soft copper won't be as pretty, I feel like there is less of a structural compromise since the exterior wall is 2x4 sheathed with OSB behind brick. Are there arguments against soft copper? Thanks in advance.
