Hi everyone I'm new here I'm renovating a small portable building turning it into a camp and I'm having open cell spray foam insulation installed and don't want to undo the sound damping of the foam with a alot of holes. I'm trying to find out if code friendly to install water lines and drain lines on the walls instead of in them?
These are all interior walls freezing isn't really an issue but all pipes will be easily accessible from inside. Where all plumbing and water connection to main lines and septic tank shall be insulated and protected. I'm trying to avoid corrupting the spray foam due to extreme loud neighbors,
