Hi guys. I want to replace my toilet pan and at the mo, it is cemented up to the soil pipe with a sort of lip. I do not fancy to chip away the cement between the soil lip and the pan outlet and i think it will take ages to saw through the soil pipe which is not made of plastic but looks like very heavy metal.....could any of you give me any tips on how to disconnect it please?? Also i would like to tile the floor and therefore the pan outlet will no longer line up with the soil pipe, can i use some sort of flexible trap and what diameter should that be? Apologies for those many questions. Thank you for answering.
