Marty - thanks for the advice. One follow up question though. If the by product of the gasses condenses and flows back into the black tube, shouldn't the water flows through the skinny black hose into the outside box trap? There's water in the box, even after I drained it last time.

Also, should I be concerned about the water seeping through the black plate where the black hose is connected to the 2" PVC? Any repairs there needed?

I'll get new PVCs and run the pipes again rather than trying to clean them out. Seems easier.

Thanks for all the help. It might take me a while to actually do this, but I'll report back.

Most of the water drains back from the 2" pvc and into the bigger black rubber hose. Some ,but not much, will come from the smaller hose. If you still have a leak where the 2" pvc glues into the black plastic on the furnace you'll need to replace it. All that hard black plastic and the flange is one piece. There's no way to take the pvc out once it's glued in so the whole assembly will need to be ordered. Don't panic it's an easy job. Running new 3/4" for the coil and humidifier will take you 20 minutes and cost and it's cheap. The other costs a bit more but will be even faster. Took me longer to peck this responce out then the whole job will be

It appears that this is a common problem... Here's what I found today.

I'm happy to report the issue was solved a few months back. The curved PVC on the left side was the culprit. It was completed blocked with minerals.
