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?

Thanks

The sound is probably going straight up through their ceiling,
reflecting off the roof and down into your bedroom. Made worse by the
night quiet.

Is there a solid dividing wall in the roof space, or is it open as was
popular at the time of building?

(Assuming all are on the upper floor)

The roof space (tiles) was open but the last owner got it bricked up
though I wouldn't say to sound proofing standards. Both bathrooms are
upstairs though mine is on the outer wall and hers is on the inner
wall adjacent to the spare bedroom.

I'm not too sure of their exact plumbing - I know the last neighbour
put in a header tank for the shower, mine is mains fed, but there has
always been some noise even before that which I'm fairly sure arises
after the toilet has been flushed.
