Got to break free.
Okay, so your pipes are doing Freddy Mecury's version of, "I've got to break free."The Cause. What's happening is water is rushing past an object that begins vibrating. This object, can be the washer on a tap. Washer on a ballcock/float valve or closing flap on a gate valve. As the water rushes over the washer, it starts vibrating.This in turn, causes you tap washer to start jumping up and down.Your tap starts turning off then on, 100 times a second. The water stops then starts, over and over, bashing into every change of direction you have in your plumbing system. Depending on how well your pipes are clipped, determines the kind of noise you hear. (Pipes that have little or no clipping, don't need any thing to trigger the water hammer, but this is usually quite rare.)
Clipping
Your know when little or no clipping of pipes has occured by the different sound of the water hammer.Instead of a continued banging while a tap is run, you experience nothing until you turn your tap off. In this instance you will hear one big thud somethimes followed by a shudder of pipe work. (lasts 1 or 2 seconds.) Decision time: Determine which of the following, best decribes your problem. If your sound is a continual banging only when 1 paticular tap is used then try my

For a water hammer that occurs only after tap is turned off continue learning. To solve the clipping problem try this. Find out wether your pipes run in your ceiling or underneath your floorboard. Purchase some pipe clips (very tight fitting).If need be, measure the diameter of the pipe, by holding your tape measure above the pipe and looking down on it. Note down if pipes are copper, galvinised or plastic. Better still, if you have a digital camera, take a photo to your plumbing supplier. If the clips are not really tight you can pack with small bits of material. Clip at about 1m/3ft intervals. The hard part about this is, the main culprit can be in a wall. To solve this......
Water Hammer arrestor
The water hammer arrestor works by introducing a cushion of air.This takes up the impact of the water moving at a great speed that stopping suddenly. ie a tap slammed shut.I like to visualise it, as someone jumping off their house onto concrete, compared to jumping onto a trampoline. The concrete is hard, unforgiving and jarring.While the trampoline is soft, cushioning and best of all, quiet.
Where to install?
You need to install it as close as possible to the source of the banging.Tee into a line, screwing the water hammer arrestor as close to the tee as possible.
