Water leaks from my Toilet?

The filler may be leaking, they have a rubber diaphragm which becomes worn as well as a small cone shaped bit that presses on it and shuts the water off. If you want to vhange these fine sometimes its easier just to change the whole thing, they are not expensive. Before rushing off though check whether you need one that fills from the side or the bottom and you will need to turn the water off first.

You may need to change the ballcock washer, its this that go's up against the water valve to stop the incoming water.
