Connecting a new WC waste connection to an old ceramic collar

Dear Amy. Thank you for the MyBuilder question. Sure it is possible, take away the bulk of the pan by tapping around the bend until it breaks. Don't let any bits fall down the hole by poking a cloth into the remaining china / collar. Wearing goggles, and gloves always. Gently chip away at the old wc china and with luck you may save the waste collar. If the collar does snap off you can always tidy it up with a miltiquick connector. Note, unless coming up through concrete the collar is sometimes holding the entire below ground pipe up... be careful. Good luck, Bob.

Yes it’s possible but you will need to carefully break the ceramic outlet of the toilet and remove the toilet pan. Then with a sharp pointed chisel chip out the rest of the ceramic outlet remains from the collar. Be careful with this as you don’t want to break the collar. Once all the ceramic debris has been removed then chip away the cement until a new multikwik connector can be pushed down into the collar. Then you can fit a new toilet. It’s doable but care is needed when chipping out the ceramic from the collar.

With the current materials on offer I doubt it’s a difficult fix, it’s hard to quote for something I haven’t seen but doing a quote without seeing something is always difficult. The previous answer is correct but, in my experience it will fall apart as soon as you give it a gentle nudge. If things are installed that long the only thing consistent is the clay pipe, it’s Victorian, like our sewers and the London Underground. It’s the things installed after the clay pipe that’s seems to be a problem? If the 4inch clay pipe is correct it could be that the cement mix/installed incorrectly could be the problem. Can’t say without seeing it personally I’m afraid.

As I rae and others,its achievable,have done it many times,50,50 chance,can be got over,
