I have watched the videos that Delta has made, but none of the models shown look like mine once I take it apart. It has a brass part that looks like a RLS adjustor (ie. there are teeth inside it, like it could be adjusted right or left), but the stop piece is plastic and seems to be attached to the rest of the fixture in the wall so I cannot turn it. The brass piece cannot be adjusted because the plastic piece won't move. Maybe this is an old model or something, I am not sure as we just moved into our house and we're not sure when the bathroom was updated last.
