you're ok. It's called a 'wet stack'.

Aren't wet stacks only allowed on the same floor?

Dear Readers,

I need advice on a plumbing code question. My existing 1st floor
bathroom vanity appears to use the drain from the 2nd floor toilet as
a vent stack. Appears that both 1st and 2nd floor toilets have no
other fixtures draining into their respective drains.

Question: does the plumbing code allow me to route the 1st floor
vanity drain into the same drain from the 2nd floor toilet (which is
being used as a vent for the same vanity)? Or must I continue to have
a dedicated drain for toilet?

Your comments are appreciated.
Regards,

Anthony
