Connecting a toilet on groundfloor

[mutley racers]

Hi all. I don't do much drainage so after some advice. Is it possible to cut a tee into the top of a long radius bend at the bottom of the soil stack for a downstairs cloakroom?

Sre images attached.

Thanks

I would say no, but maybe a little higher than you propose. See attache, 1.11

Yes, was looking at that picture as well. The building control guy actually has said it is OK?

If they say it’s ok, then roll with it, they’re the one‘s “in the know” as they’ll be signing it off?
