    Looking for a bit of advice on the best way to do things with a new soil pipe, apologies if its not complexity clear what im trying to do but i'll do my best to explain. The current layout is this:


    I need to move the soil pipe to the side of the house for the new bathroom and for the new downstairs toilet. However to save cost I would like to reuse the existing sewer pipe. The issue is how best to connect the vertical soil pipe to the horizontal underground pipe, as i see it there are two options:

    Option 2.PNG

    My concern is clogging where the vertical pipe meets the horizontal pipe from the downstairs toilet. What would people recommend?

    Get building control involved early as it will be down to them, no matter what anybody else recommends.

    I just ask them now how they want it and follow there advise. Puts you in a good position as works progress.

    The top one will be better keep away from the house to avoid the footings and any other services as above building control will need to pay you a visit . Cheers Kop
