The toilet cistern started humming two weeks ago. We lived with it for a while, but it got louder and louder. I discovered that it sometimes stopped if we ran all the taps in the bathroom at once. It seemed a little wasteful, but then again it does rain a lot in Lancashire.

Malcolm mentioned that in his old house he had a Humming Cistern Problem, and he had a plumber in for something else, and told him about the hum. The plumber fiddled with it and the hum went away. I fiddled with the mechanism inside the cistern, and it did seem to go away,
