    Hi All,

    I'm re-doing the downstairs toilet.

    So far I've:
    Ripped out the old toilet suite and sink.
    Re-routed the CH feed and return from upstairs to come through the garage and through the back wall of the toilet - and I'm going to bury them in the screed (boxed in access for the joints - Speedfit to copper). This used to come down in the kitchen, but I re-routed temporarily when replacing the kitchen via this new shorter route, and now making it permanent.
    Re-plastered the walls and ceiling - with 1 still to go, once I've finalised what I'm doing in the room.

    One major thing that's bugging me is that the room is 800mm wide, but the toilet waste is not centred (see centre line in photo).

    I'd like to re-centre if possible, but was wondering if there's anything better/easier I can do to save the hassle of digging up the concrete and messing around with joining to the old pipes. I'm planning on boxing in the cistern and having a back to wall toilet, with a button flush on the boxed in section. Currently the distance from the wall to the soil pipe centre is 220mm. I've not yet looked to check what's possible with his distance for boxed in cistern and back to the wall toilet - fingers crossed I can do this!

    If there are adapters, I'm also not sure how to join to the current clay waste pipe. It seems to be a little bit damaged where the current plastic toilet waste feeds into it (see photos).

    Open to all suggestions and not afraid of getting stuck in - I'd prefer to do this the 'correct' way.

    I've also attached a photo of where the toilet waste goes (just under the LHS wall) into a chamber in the garage. The sink waste is concreted in, and there is no vent at all. I've guessed that's why the sink trap used to gurgle sometimes. If someone can point me to the correct practice for this, I've seen things mentioned such as AAVs, but unsure where I would place (hopefully I wouldn't have to have this on show). Similarly not afraid of digging up in the garage if necessary.

    Since this house was built in 1969, it appears each owner has bodged whatever they have had done - I'm on a journey to put right whatever I can.

    Many thanks in advance for any responses/help.
    Mike

    @CBW thanks for the info - but I'm struggling to see what would fit where. Could you give a little bit more description please?

    I'm probably being slow!
    Thanks.

    An alternative is to use a flexi pan connector

    The drain connector into to ground connection, the 45 spigot elbow into the drain connector, a short stub of soil pipe into that 45 spigot elbow and then the 90 degree pan connector. Or you could opt for the flexi route as per kidgreen61.

    Is there a short flexi that will fit without the curve being under strain.

    Finally getting round to doing this...decided to dig it out and centre it properly. When doing so, I've found out there were already some adapters on the original clay pipe. Will post some more photos after I've got the rest of the concrete out (slow progress with my SDS chisel bit).
