I've had most of the plumbing in the house exposed at some time or other
but have never been able to find the source of the problem. Only a
couple of 3M or 4M stretches have never been able to be checked so I
fitted it in a section as close to what I presumed to be the source of
the hammer as possible.

It's not worked. Nothing has changed.

I fitted one of these recently to cure a problem with a noisy toilet
cistern; I fitted it at a convenient location in the cold water pipework
(several meters away from the loo) but it did absolutely nothing; I then
demounted it and repositioned it immediately below the cistern where
it's unsightly but reasonably effective. Certainly not perfect though.
