hi it will be the ball cock thats at foult you need to take off the ball cock and clean it out or even have to replace it very easy job if you were/are very handy with spanners after turning the water off,my advice is get some one you can trust to check this out, it is quite easy to do even to fit a new ball cock and they are very cheap to buy about £4. 00 in stockport/ manchester areas. bob
