I recently bought a dehumidifier with built in pump for my attic. There is an HVAC unit in the attic with a condensate drain pan and drainage pipe. There is (what I think is) an open access point in the pipe, and I'd like to run the dehumidifier's pump tube into this access point. Is this kosher? Is there a better way to do this? Thanks.

Sure, but the risk is that if the condensate drain gets clogged then you're pumping water into your air handler. The vent is there for a reason, so don't hard-connect to it, it needs to be functional. Just run a smaller diameter tube to it.
