My old Dorf shower mixer is no longer mixing. It now only produces hot water. I've removed the screw from the centre of the handle but it still refuses to come off. I can't see anything else that would be holding it on and am thinkining that someone might have glued it on. Any suggestions?
1st make sure water is off, under neath the circlar body ther should be an alan key grub screw that holds the shower on,remove shower,then unscrew the keep plate,
