Why does my shower make a knocking sound?
A loud knock when you turn on the valve is a symptom of water hammer, which is caused by excessive pressure in the pipes. You can quiet some noises by servicing the valve, but to dampen others, you may need access to the pipes.

Tapping in walls could be attributed to the presence of pests such as mice, rats, termites, and wasps, to mention a few. Expansion and contraction of pipes could cause tapping or clicking sounds that may be heard through the walls. Heating ducts may also emit tapping sounds as the heating system turns on.

If you have a radiacal difference in pressure between the hot and cold, that could give you some grief. This could be caused by a restricted flow from the water heater, or somewhere in-line, especially if you used any galvanized iron piping – that can often end up nearly full of rust scale.
Why do my plumbing pipes make a knocking noise?
