I am updating my bathroom and the new toilet I ideally would like to shorten my waste-pipe slightly to fit the new pan. I know some soil pipes are made out of asbestos, but not sure whether that was limited to asbestos-cement or whether there are also pipes made out of asbestos-plastic (i.e. like Bakelite Cisterns). You can see a picture of mine here: https://ibb.co/ia7GJc - my guess is that this is plastic, but I can't say for sure as limited experience with asbestos. Can anyone confirm that is definitely plastic please?
