I am in the middle of replacing the suite in the downstairs cloaks and have removed toilet etc. I need to raise the floor with levelling compound by circa 20mm and have a vertical waste outlet through the concrete floor.
The 103mm clay pipe seems to have some form of collar (internal dia of 160mm) embedded in the concrete as a termination as the photo below shows.
I want to make a neat job and use a swan neck connector to the p trap toilet i will be fitting (I know I will have to box behind toilet cistern as is the norm). What should I do, I was thinking of chipping away at the collar so that I can level up and tile right up to the plastic outlet pipe inserted into the 103mm pipe. Is this sensible or should I just leave well alone due to risk of damaging clay pipe and just fill collar with mortar and paint l;ike was done previous.

Any experience / help most appreciated.
