    Nick. Years ago I found by accident that valve bounce was the single most cause of “hammer”.
    I was on a job that a Hammerchewer or DIY had done & had run all the copper pipes hanging from the bearers with no clips. There was a horrible Hammer, so I solidly clipped the pipes by hanging 4×2 timber down to the pipes & clipped them. The hammer continued & after checking all open controll cocks found that by turning off the cistern cock the hammer vanished. hence We now use Ball Control valves & never have a problem except for jumper type taps – ceramic disc taps fix that problem.
    Vibrations are a different thing though & clipping & Silicon will fix that.
