    Hi all,
    have got a copper stack in a building, cant take it out and replace.
    Any ideas of the best way to connect? I believe it is 3". Toilet is too far out to connect straight in anyhow.

    Was thinking
    McAlpine Straight Extension Macfit - 3in | City Plumbing Supplies

    would it make a good seal to the copper?

    Flexible Connector 112 - 112mm

    but this will need to be tightened up a fair amount to take up the extra inch, also might deform the plastic when doing up?

    Advice appreciated.

    Depends on the internal size of the copper first link would be better if it's the right size

    Measure internal diameter 1st as Shaun says. Remove any 'raggy' edges with half-round file on inside (if misshapen use 2 hammers and tap back into shape).
