Need new water inlet like this!
I believe that you are likely looking for a plumbing fitting referred to as a drop elbow
I had been considering what would be needed to re-plumb the water inlet on my Minuet -- had no idea what fitting was needed -- then discovered that it looks just like this fitting that was used in plumbing the shower in my newly remodeled home bathroom.
