Could you describe the layout in a bit more detail please. You say the soil
pipework comes in through a wooden wall (stud partition ?), but where is this
wall in relation to the WC ? I was under the impression that the soil pipe was
outside the house, is this correct ?

The house is timber framed and timber clad, i.e. entirely 'wood' - but
the internal walls seem to be constructed of a cardboard/hardboard type
material.

The soil pipe is outside the house.


In which direction does the WC face ? Does the waste outlet from the pan point
toward the outside wall and go through to the outside stack ?


The rear of the WC points straight at the outside wall, behind which is
the soil pipe, there's a junction just above the ground outside which
branches off into the bathroom to connect to the WC. So the soil pipe is
on the other side of the wall, immediately behind the WC.

More information would be most helpful please.

The existing WC fits OK for two reasons - first, its outlet is lower
than the new one. Second, whoever installed it dug into the concrete
floor to lower it an inch or two. I guess they did this because they
were faced with the same problem as me. I want to fill the hole in the
concrete and level the floor.

So I'm faced with a drop of about 90mm between the WC outlet pipe and
the CI pipe which comes through the wall from the soil stack. In other
words, the bottom of the WC outlet pipe is 140mm off the floor, and the
bottom of the pipe coming through the wall is about 50mm off the floor.
And there's only about 105mm horizontally between the ends of the pipes,
which seems to rule out the use of a flexi pan connector. I can't bring
the WC out from the wall due to lack of space.
