Anybody come across a concealed cistern with a handle flush that is connected by a bar to the flush valve. The panel that the handle goes through is removable but the handle seems fixed to this bar so although I can loosed the panel it will not come off until the handle is removed. Does the handle normally push on after the panel is fitted? I have only come across concealed cisterns with cable connections before. I do not want to try and prise off the handle unless I am sure it will come off.
