    Hi chaps, I have a 4 inch cast iron toilet waste pipe I need to extend. unfortunately now I have cut the collar off the pipe and can now measure the bore of the pipe, I have discovered the inside diameter is 97mm. The multikwik extension pipe I have is only suitable for a pipe diameter of 99mm to 105mm therefor too large for my CI pipe. When I try to fit this, the extension pipe buckles and will not provide a watertight seal. I have checked the multikwik website and I notice they do not make an extension pipe for a 97mm pipe.

    Any thoughts on what I can try to do next. Perhaps there is a sleave available that I can 'jubilee clip' to the outside of the CI pipe (OD 110mm).

    many thanks

    Multikwik do them in different sizes. I have always managed to get by with them but as you say this size isn't listed so try McAlpine or Hepworth.
    As a worst case scenario you could always go back to the next joint in the soil pipe and fit a caulking bush
