Constant humming noise

Crumble2018

We moved into our flat in December. I noticed that I could hear a faint low frequency humming noise in the bedroom at night, and just figured it was something from the neighbour below. However it has got worse over the last week and we can now hear it in other rooms too. We have ruled out the neighbour noise and turned off the electricity and the noise is still there.  We now suspect that it could be coming from the pipes as the sound is quite prominent in the cupboard where the stopcock is. Any ideas? It’s driving me insane!!

Ha ha - I already did! This is definitely coming from inside though - nothing outside at all!

If you put a glass to one of the pipes, does it sound louder?

If you can't get your ear to the glass, because it's inaccessible, use a batten of wood to touch the pipe and place the base of a suitable cup or mug against the end of the batten.
