Tee into a 3.5 inch Copper soil pipe

[ksareen]

Hi,

I am installing an additional loo downstairs that needs to be connected to an existing 90mm/ 3.5 inch soil pipe (copper) running to the toilet upstairs.

Found something like this but could not find not a Tee:

WC Extension Connector for 3 1/2in MKEB - Multikwik - Guttering & Drainage -Building Materials - Wickes

Can someone post an idea or send me a link for a connecting a 110mm pipe via Tee into a 90mm soil pipe?

Thanks.
