Smell / water in my sink from neighbour ?

[AaronUK]

Over the last few days I have noticed that when my neighbour uses their washing machine I get a little of their water in my kitchen sink. It makes a gargling noise and fills my sink with some soapy water. It's
smells of rotten eggs.

I am on the 1st floor of a 4 story flat. Why is this happening. Is it a problem in my flat? Thanks.

Where is the neighbours flat in relation to yours? Its likely a partial blockage in pipework somewhere, water cannot get away quick enough and is backing up into your sink.

There is 3 on each floor. Not sure what neighbour is using theie W.M. Do you think it is a problem with the stair drainage or my flat. It is hard to tell how it works as the building is over 100 years old.

some photos of whatever pipes you can see would help. Where I come from the 100 year old buildings have the drainpipes on the outside of the house.

Is there a maintenance or management committee.
