I am trying to remove the siphon system in my toilet so I can replace the diaphragm to make it flush properly again.
I have got through the disconnecting the flush system, emptying the tank etc, but have got stuck.
The toilet has a "Shires Twinflow Syphon" but the cistern sits directly on top of the pan unit, and I can't seem to undo the siphon unit from the inside of the cistern.
There is no space between the pan unit and the cistern for me to get in and undo any retaining nuts.
Am I going to have to take the cistern off the pan to be able to change the unit ( seems a bit much to me) or is there another way???
Any help would be great.
