I'm in an old (1860) semi-detached cottage and hear when the neighbour
has water running in the bathroom - I think it is when the cistern is
refilling. It is quite annoying at 2am.

The water pipe from the mains is shared but I'm not conscious of
similar sounds during the day when I guess the kitchen taps must be in
use.

Anything to be done? Is it likely that I'm hearing the sound direct
or through our water pipes? How do I ascertain?

IME (we have two mains incomers, separated by maybe10-15 m of
underground pipe). We get noise in the pipe of one, when the is draw on
the other one (but not the other way round)

If it coming through the pipe it's more a hissing/water in pipes kind of
noise as opposed to actually hearing water trickling if you are hearing
the sound directly.

If is a tricking/running water sound it is maybe coiming through the
rood space - or some sort of gap in the wall?
