hi chrissie,
it sounds like the washer needs changing on a ball valve. its a common problem and easily solved.
firstly try and ascertain whether it comes from the ball valve in the toilet by flushing and listening for the noise also feel the cold water pipe as it enters the cistern to check for vibrations.
this is the most common cause and you can get a replacement washer for a few pence.
if its not the w/c it will be a ball valve in a cistern possibly in the loft.
hope this helps
KJ
