I know it sound like water hammering, but why just this toilet and not
the other ones in the house? Read all my post.

Different fill valves operate differently. You may have one that uses
the water pressure to help close the valve quickly. The ones that
slowly come to a stop won't cause the water hammer, but they too can
have their own problems.

I installed the American Standard dual flush 6/3 liter 4035 toilet just
over a year ago. Ever since day one it hammers when the bowl is filled
and it also sounds like another hammer when just after the small flush
button is released not the large flush? Is this a case of design as no
other toilets in the house makes such noise. Ps American Standard won't
return my email.

Thanks
Sounds like a plumbing problem in the water supply. it's called Water
Hammer. Google it.
