Water is collecting and the runnung out of the bottom of the unit when it operates. Do not see water coming out the drain tube on the side of the unit. Unit is at least 12 yrs old. A premier 90.

I turned off the water to the humidifier.

Could be a few things (condensation finding its way out of the furnace, secondary heat exchanger, humidifier, etc.), but you can learn more here: http://answers.yahoo.com/question/index?qid=20061003161523AAHsuMD.

And there is a lot of good information here: http://www.angieslist.com/articles/furnace-water-leak-explained.htm.

In any event, this could be a sign of a larger problem either occurring or about to occur and could lead to larger leak or more substantial damage to the furnace. I didn't recognize a problem in a furnace in a rental unit I had and when it let go there was water all over the place. This raised issues with mold and all kinds of things.

The water is leaking out the bottom of a brand new high efficiency Rheem 2-stage furnace. All of the drain hoses were hooked up to the main drain tube, but this water seems to be coming out on the opposite sided of the furnace below the blower. There is no collection in the blower compartment, so it must be coming from the burner compartments. In order to access the burners I would have to remove a lot of components. Without getting into the burner compartments it is impossible to tell where the water leak originates. The furnace is a 75,000 BTU Rheem high efficiency manufactured in March of 2013

Check the slope of furnace..... Very important on condensing furnace to slope towards collector or drain... If you don't heat exchanger will be compromised
