Sounds like your ABS furnace vent pipe/fitting is cracked. Could be allowing CO into living space. Cut out the bad section and replace using ABS pipe, fittings and glue.

Can you post a picture?

I should also add that if it is the vent pipe that is cracked the reason you have water leaking is because water is a byproduct of the combustion of natural gas.
Normally that water would drain back to the condensate drain, but it sounds like in your case the cracked vent pipe is letting some of the condensate escape before it can make it back to the drain hose.

In a way it's a good thing because it alerted you to a dangerous condition.

Is there a crack in the flexible rubber cap or is it a crack in the ABS? If that flexible rubber cap is cracked it should replaced.
If the ABS is cracked it may be from over-tightening the worm clamp and it may be possible to repair it with ABS cement.
Also, are you getting any condensate from the drain pipe...I just want you to make sure the condensate hose isn't plugged.

Thanks again for being so helpful,fabrk8r! I have tried "pvc cement"---tomorrow morning i'll go get some "ABS glue", and try that. As far as cutting out a section and replacing it, the moulded "Y" is right where the water.................... ,well.......... just below that point, and above the rubber cup, is always wet.I wish i knew where i could get that "black section" and replace it.Calling all over is on my agenda for this also tomorrow....should the ABS glue not take care of it... BTW -this thing has leaked abit for 15 years.I had no idea it could be dangerous..so thanks for the heads-up on that too. bob s

If you have been trying to stop the leak for 15 years on the same unit, it is time to replace with a more efficient one. 15 years is past the prime & operating efficiency, that with cost effectiveness to maintain.

Good point gregzoll well taken...........but....-----------This air-ease hasn't give me a headache at all in those past years..i have a professional, come check out the burner and the flame. then i oil it up and clean out the fan area and humidifier on a regular basis ,change filters regularly. I won't send her to the boneyard yet. she runs quiet.actually this is the only complaint other than the ..pvc..outside.. getting plugged up by a "hornets nest occasionally ,each year"

In that case, just pull the PVC and replace with new piping. 15 years is a long time for allowing the acid from the flue gases to eat at the piping. If it was me though, as stated before, I would update to a newer more efficient system.
