    Hi all.

    Need to cut out a section of cast iron soil pipe which is outside the house. I need to cut just above ground level to fit a new plastic section for a toilet waste on a stack that is 3 stories high!!!!
    I know I can get adaptors for the job but I am worried about supporting the pipe above. Replacing the whole thing is not an option. Can I do this, which is the preferable option, or will I need to
    fit a macarator in the new loo and run 40mm pipework into the cast iron vai a boss? Hope you can help.  Spiked
     
  2. The soil stack should be in 3 or 4 sections, each section should have a large collar at the top ends with a large fixing either side, usually a large dome headed nail, if you cut below these the rest of the stack will stay in situ.
    You will then have to use a slip collar when you connect back, from cast to plastic.
