water hammer

[newby3]

Hi

I got this water hammer problem (banging noise when turning off the cold tap or washing machine inlet valve closed) recently. I think it started after I turned off and on the stopcock to repair a toilet overflow leaking. My quesion is, shall I leave the stopcock fully open or turn it down a bit to get rid of this water hammer? I have seen contradictary suggestions on the web: some suggest turn down the stopcock, some say to open it fully. Many thanks.

Try closing it and then opening it half way and see what effect that has on the flow and the noise.

Its just trial and error!
