Thanks Grandpa.

So, what is the difference in hooking up a sink to the side of the
sewer vent than hooking up a piece of flex hosing that goes down.

Maybe the trap? Is it b/c there is always water/gunk in the trap not
allowing the gases to go up through the sink?

Precisely. That's *exactly* what the trap is for. Many people believe,
mistakenly, that the trap is there to catch objects and stop them from going
down the drain. Nope. It's there for one reason: to keep sewer gas from coming
*up*. And that's why it's important for there to be water in the trap all the
time.

My exhaust fan hose is always going to be dry so that would be a
problem. Hmm....maybe not such a good idea?

How many times do you need to be told it's not a good idea, before that
finally sinks in?
