Isn't that taking forced air and venting it directly to the
outside through the DWV?
Seems like a big leak.
For every Cu. Ft. of air that is pumped to the outside,
another ft. of unconditioned air is trying to come in and replace it.
LOL reminds me of what my dad used to ask:
"are you trying to air condition the whole neighborhood?"
My condensate drain line is only 1/2" diameter and drains
to the flower bed outside and I've experienced a
clogged drain line once in several decades.
After that I started taking a shop vac to the outside end of
the line every spring with no problems since.
it's probably fine to do so but I'd be a little nervous tying
directly into a drain (waste) pipe.
If get it that it's on the vent side but seems like it
could still get odors over time.
