The toilet in my downstairs bathroom has the soil pipe coming up
through the concrete floor. I would like to change this to a hole in
the wall version and my initial idea was to just cut the soil pipe
outside (Clay) and join to plastic pipe and take through the outside
wall. However because the inspection chamber is only 600mm from house
the pipe is surrounded by concrete make joining to it impossible. If I
were to remove the old pipe can I cement in the plastic soil pipe
directly into inspection chamber and do I need any special fittings.
Its a brick type chamber with the pipe cemented in place?
