I'm in need of some inspiration, show or tell me how you have plumbed through walls(I love pictures). I'm about to install a water mixing station in my garage with an auto water change system that I need to plumb through one wall to my tank. I'm looking for clean installs that won't be too much of an eye sore to keep my wife happy. I am thinking about using 1/2 ro tubing on the inside and plain pvc in the garage. I will need a total of 4 lines to pass through.
