    The waste pipe that's been concreted into the building wall, and runs out into a cast iron soil stack has a crack in it. It is a part of the soil stack and will have to be cut out/or smashed out. If I was to cut the cast iron below this point, put a pvc branch in with a pvc to cast iron soil pipe adaptor, replace waste pipe from the pan to the new pvc branch and replacing the cast iron pipe, above the cut with pvc soil pipe. Is that acceptable practice? Or should I just replace all the cast iron with new pvc soil pipe? What is best?
    I found it difficult not ramble as there are lots of little bits that make up my first plan.

    Either either is acceptable just need to get the right joint as you say for the cast to plastic transition

    My first plan worked in my head but I just wanted to make sure it wouldn't be work frowned upon my others. Cheers for the rapid reply.

    How much would you say is the usual cost of such a job?

    Take the opportunity to replace the whole stack i have had them rot out form inside out allow 5 days work to replace and making good plus materials and scaffold for safe access you will also need to dispose of the old stuff most scrap yards will take metal but dont expect to get paid anything for it . cheers kop
