Victorian toilet waste issue

[cyclog]

Hi, I have a Victorian toilet (house c.1890) that I'm looking to replace, mainly so I can fit a sink waste like this into the soil pipe as no easy way to exit the sink waste: https://mcalpineplumbing.com/wc-con...deg-flexible-wc-connector-universal-vent-boss

However the soil pipe seems to be concreted in and I'm a bit reluctant to have a go gently uncovering it.

Does anyone have any thoughts on:
1) if i could somehow tap a 32mm waste into the existing soil pipe (to not have to replace the toilet)?
2) what i'm likely to find underneath the concrete? I assume a clay soil pipe hopefully in a good state!

Many thanks!

Sadly, not a chance!

2) what i'm likely to find underneath the concrete? I assume a clay soil pipe hopefully in a good state!

That's the most likely - clay 4" probably with a collar.

The easiest route to break out the existing pan spigot is to break the pan to the point where you can stuff a rubble sack or two inside the spigot and then gently break the spigot up to the point where you can clear the clay pipe spigot - the rubble sacks are to stop chunks of the pan/mortar falling down the clay.

Victorian drain - 60's toilet, 60's bodge. As Notso says + wear thick gloves - ceramic will cut like a razor
