The rotary flush knob on our C4 was not delivering a full dose of water, took it apart yesterday, seems the plastic bellows (see pic below) had collapsed over time and was not expanding to its full size, took it out and placed it in a jug of very hot water, this softened it, blew into the hose to expand it, then ran cold water over it, its now back to full height and working as it should.
Will be interesting to see how long it holds up, certainly a good emergency fix.

Santa, I just love those sort of DIY projects. Some of the time you have to eventually get the new part, BUT it is fun trying. It is easier to just buy the new bits, BUT not as much fun eh?

Very handy to know, Santa
So thanks for that information
We all know that it is sometimes hard to get parts, when travelling away from the populated places.
The old water in a cup trick, will help while waiting for new parts
A cup of water poured around the bowl, will do (more or less) the same job, as the water pump

It really is a simple fix, the most difficult part of the job is taking the mechanism apart and reassembling it, no tools needed, it all snaps together.
New bellows don't seem to be available at the moment.
Fortunately our bathroom/toilet cubicle are combined, in event of the bellows failing completely we can us our shower hose/tap to flush with.
