    Our outside downstairs sink drain (gulley?) fills up with sewage (in the form of nappies) every time we have a shower/empty bath. This has happened before with our neighbours on our left (I think the nappies are coming from the house on our right, but they deny it).

    Our bath/shower pipe is on a different run to our downstairs sink so cannot understand why the sweage is coming up there - some kind of back pressure? Where would the blockage be - somewhere between us and our neigbours to our left I guess?

    Need a sketch really. Look in every available manhole.

    Are nappies really supposed to be flushable?

    Of course nappies aren't flushable, that's what's caused the blockage?!

    I'm puzzled why I am getting crud coming up through a drain that is not directly connected to my/my neighbours soil stack. They connect somewhere - probably 15 feet away in the garden but that is some back pressure to force it out through a different pipe.

    have you tried rodding the pipe with the flat disc atacment, may be something else causing the nappies to come back up your way

    Have a chat with water company/council - they may be able to help with the source of the nappies. They can only be coming from one of your nieghbours.

    Perhaps a camera survey would be of help/

    Have managed to cure this with a plunger after letting bath water out, thanks for all your advice.
