I have an Ideal Standard Concept Cube Toilet with a dual flush. The short flush works fine but when using the long flush the button sticks in the down position and the water keeps running. Touching the button again stops it. I have been trying to find online instructions as to how to adjust the mechanism but seem to keep going round in circles. Any suggestions?

It may work for you and has worked for me good auld vaseline/petrolium jelly and grease all moving parts relating to and including the buttons its a clean harmless grease.
Also a short quick squirt of WD40 for parts that you cannot get at with the vaselene.

Another tip using vaseline/petrolium jelly

I use vaseline on my car battery terminals to stop/reduce the corrosive build up seen on many positive teminals also. To clean a corroded terminal without disconnecting bicard in water mix usually does the trick. Then clean it and vaseline it
