Toilet horizontal soil pan connector with multiple bends

[Rybo_1]

Any chance of cutting pipe flush with floor and using a Mcalpine DC1 fittings which fits inside pipe and and then a branch in to that? You'll be 120mm off the floor so roughly 60mm and you can go direct to pan and a 90 pan con

I unfortunately cannot modify the vertical soil pipe, its shared with the upstairs neighbour, and it is made of metal or ceramics I believe, so I cannot modify that part. The floor is concrete.

If I raise the toilet pan somehow, how much gradient should I have at least with all these bends?

Thanks

Adam you are misunderstanding I think. you should be able to cut the part fixed in the floor flush with the floor and do as several members have mentioned above. if you can post pics it would be a great help.

If you're ground level or first floor, is the loo backing onto an exterior wall?
If so, is there an exterior soil you can tap into?

Modifying the vertical soil pipe is not an option, and using a different one (or new one) inside or outside the building is not an option either.

If I raise the toilet pan around 8 cm, would that be enough with all the bends?

Thanks
