lol. Well it was worth a go eh!
Where in the house is the basin? Top floor, bottom floor, both taps or just one?
Just gathering info for others to help you. My guess and it is only that is water hammer from air or pressure related, are they new taps by any chance?
Is it when you turn the taps off. If it is you water hammer which caused by pipes not clips very well if at all. Try turning the stop tap/cock down a bit to reduce the water flow usually does the trick. Or could be a loose washer in the tap.
