Replacing toilet with cemented flange ring

difficult one without seeing it, but if the old pipe comes through the floor and its brown with a gloss finish to it then its a clay pipe so dont go smashing anything off this as it will cause a crack probably under the floor!! there are numerous fittings available to connect your new 90 degree pan connecter into the existing , make a paper template of the hole size and take it to a plumbers merchant for advise rather than a diy store. good luck

Hi Richard, I am almost sure that the pipe will be clay, if you have a grey cement collar, as a seal. We cut the visible pipe with an angle grinder to separate, then we inflate a drain test bag in the hole, a little below the bottom of internal pipe, to stop pieces falling down the drain, and to support/soak up vibrations within the pipe. Then nibble away at the remaining pipe/cement with a TCT chisel, always pointing inward, and clearing regularly until we have enough exposed to fit our new pipe. You will probably only need a multi-kwick connector, maybe with an off-set (readily available in various lengths). If you set up your new toilet against another wall and measure the dimension from the outlet to the wall, and compare this to your existing measurements, it will tell you what you need. Regards Simon
