soil pipe / sewer connections.

Fitting drainage soon. Above the rest bend I will need a short length of pipe to pass up through the solid floor. In this situation would the brown pipe rising through the floor usually end in a socket somehow, or just a cut off brown 110mm pipe ? Is it OK to have a short length of brown above ground before the black soil pipe begins (so I don't have to fuss too much about the finished floor level) ? Thanks, Simon.

I think the brown pipe doesn't have uv protection that is why it is not normally suitable for above ground use. If it is internal, I personally wouldn't worry about a short riser in brown.
