It is called "water hammer" when the water resonates (sloshes backwards and
forwards) in the pipes sometimes one can hear it, and sounds quite
alarming. I would not worry about it if it were mine. If you put your
hand on the pipes, you should be able to feel the pipe moving slightly.
Put a lot more plastic clips on anything which moves.
