Three years ago I ran some plastic tubing (which I believe was
polypropylene) from my water softener in the garage, through the brick

some advice if polypropylene is the best material to use for this

UV rays destroy it paint it next time . As for what type of paint you
can even use latex. I would just use PVC it’s used quiet often for
chemical piping
