you need to free the sliding mechanism inside the outlet orifice it gets clogged up with muck and needs some persuasion to slide - moving the normal hand held slide entitled blow and vacuum often isnt enough and at times it seems to slide indepenantly of the mechanism in the outlet. a sharp stick or large screwdriver sometimes has the desired effect.
