My low-level cistern has a button to press to flush the loo. If I
simply press the button I get water hammer noise. If I press it
initially very gently, so as to release some water into the bowl, and
then press fully down, I DON'T get water hammer.
So where is the *actual* water hammer noise emanating from? I've read
before that water hammer is something to do with high pressure and
valves, but I don't get how this only started recently (over the past
couple of months).
This is the cistern internal 'gubbins':

Its nothing to do with the bit you photographed - thats the flush valve.
Its the other bit with the blue float.
Is the water inlet plumbed in copper or is there a SS braided flexible?
