have a Nabis single lever tap in my bathroom hand basin but it is getting very difficult to move it either to hot and cold or up and down. I took the small screw cover off which is in the tap pillar but could not see a screw there to remove - I was then going to take the top of the tap off to see what was causing this stiffness. Should there be a screw there or does anyone think it could be an allen key which is needed? Any help gratefully received thanks.
