I have a covered back porch and am planning an outdoor kitchen to be installed there. As luck would have it, my current washer hook up is right on the inside of the wall where I want the outdoor sink to be. I am trying to figure out how to hook up the sink so I can disconnect it in the winter and drain the lines for freezing protection but I don't want to pull the washer out twice a year (disconnecting in fall and reconnecting in spring). Has anyone brought indoor plumbing through a wall for their outdoor kitchen? Any ideas?
