I think it is the pipes and they are making strange grinding/vibrating noises which is driving us crazy!! It is hard to explain the noise but it sounds like quite an echo sound like pipes vibrating. The sound can be quite frequent but seems to stop for a while when the toilet flush is used. When the noise is happening i have lifted the toilet cistern lid and it seems to have some impact on the ball valve mechanism. Ant ideas please?
