Could it be your neighbours' stop tap that is making the noise? When
we had a similar problem recently it ended up being their problem.
But this was extremely hard to believe from the noise (and vibration)
in our own pipework. We did turn everything off and the noise
continued. Went round and found that they were suffering much worse
than we were.

Thanks, Rod. I'll finish my cup of tea and pop round. I'd rather it was
someone else's problem.

They'll "get a man out" if it is.

Cheers,
