Besides cutting out a section, is there an "easy" way to tie a 2" PVC vent into a verticle 4" cast iron pipe? I say easy and without cutting because there is no way easy way, without gutting a bathroom above, to support the cast iron pipe above where I'd have to cut it.
I also doubt this would work, because it would be for a vent for a 1st floor pedestal sink, which would create a wet-vent for the sink as the toilet and shower from the 2nd floor bath drain into the 4" cast iron pipe.
