real easy, I just did mine yesterday. You basically have 2 splices. One into the cold water line, one into a drain. Nice thing about RO systems. They use small, cheap 1/4" poly tubing. You can pretty much mount your unit where you want, and then just run 2 of the small lines to wherever the closest/easiest water line is. Any plumbing store will be able to help you further on selection of fittings etc to work with your existing plumbing
