Hi my name is Brian. I read your question and I am not quite sure whats come away in your hand. do you mean the whole assembly has come off the wall or the handle. there are no details regarding the diverter in any manuals I have, but going from the mixer valve you will need to take the end dome off as this should be a cap that is covering a screw.
