disconnecting old toilet waste pipe from soil pipe Drainage and wastage systems and plumbing help, advice and answers

[nortig]

Hi I hope to replace the old wc and fit a close coupled wc in a downstairs cloakroom but need to disconnect the old toilet waste pipe from the soil stack. Both pipes are plastic but do not pull apart. Could someone advise how to seperate them or can i cut the old waste pipe prior to the join and fit an adaptor of some sort?

Something like 8 out of ten soil pipes use push fit fittings. After years of use the connections can become very tight and you have to use unexpected force to move them. The other three stacks use solvent weld joints which means using a saw to alter the pipe work.
