Thanks Guys!

Since I am building a bathroom directly underneath, I have the walls framed but still open and I am going to route a PVC pipe down the wall. From that point, I am going to see how I can tap into the sewer line which is directly below this bathroom. If I can't tap in, I will run the line to a vent under the house.

The original A/C condensate was plumbed directly to the sewer line but I have now replaced the old cast iron with ABS. I feel like I can drill into the ABS and add a pvc fitting to it.

And, thanks for the heads up on 3/4 size. I think I will go with 1"

The A/C installer installed two pvc outputs: 1) condensate line, and 2) drip pan under the A/C. I will leave the drip pan line exiting the house where I can see it. If anything coming out, it means a leak.
