Replace soil pipe

[Doddy33]

Hi there, I'm installing a new toilet in upstairs bathroom, trying to connect the pan to the soil pipe and it looks like the soil pipe is cracking (it's probably 30+ years old at least). It's solvent welded in place, how best can I remove and replace? Thanks

You'll probably have to remove a section of the vertical soil pipe on the outside wall and replace complete with the new tee fitted ready for the toilet. It might be worth trying to fit the new toilet on the existing waste, nothing will be lost if it works, if it does crack just tape a plastic bag over the end to keep out the sewer gases, and get a plumber in.

I'll give it a go its still the cast iron external soil pipe so don't fancy getting that changed!

That cracked part is a pan connector extension going into the cast iron that's level with the tiles. The sheds have them

Yep, as per @Nige F - it’s an extension piece, Center brand to be precise. It’s not solvent welded, might be tight with silicone/tiles, should pull out and can be replaced.
