when i turn off my cold water tap (any one - even the garden hose) i hear a
'bang' from somewhere in the house.
if i turn the tap off slowly it doesn't happen.
anyone know what it is and if it is harmful to my plumbing system..
it seems to have got louder since I recently change the bath toilet and sink
in my upstairs bathroom.
I have seen this cured via installing a damper or even putting a tee in the
line if it is 1/2" pipe also use a 1/2 to 3/4 reducer then on that 3/4
reducer install a 4-6" piece of 3/4 pipe with a cap mount this vertically.
This will create a dead air space that will act as a damper for the banging.
I have seen them installed and seem to work. any comments?

That design is called an air chamber and frankly they are a joke. In a very
short period of time the air is absorbed by water surging into the air space.
Unless you provide access with a valve to drain the water and restore the air
every week this design is worthless.
Anyone who would suggest such a design is a fool. Now do you feel better that
you've been insulted?
