furnace drain leaking
I have a lennox elite high eff. furnace that has a drain coming from inside the furnace (it is a sealed 1in plastic pipe) . the drain starts up by the condensor for the air conditioner comes down and around the furnace and picks up the drain coming out of the furnace wraps around the furnace and picks up the drain coming from the humidifier. (there is a clear flexable drain coming from the furnace that slides into the drain, this drain line is right next to the sealed drain). The drain is leaking and bubbling up and over onto the floor. The drain is on the outside wall. the room is warm and I don't think the drain is frozen. before i cut the drain and try to find the clog is there any thing else for me to check? Where is the water coming from inside the furnace?
Is there a way for me to turn the water off? should there be that much water coming from the furnace?
Thanks for the help

It's a condensing furnace and it's possible to get alot out of it. Can you pull the flexible hose out and blow down the drain? If not go to the outlet and suck it out with a shop-vac.

All 90+ furnaces have to drain water away. If it were an 80% furnace the water vapor would go up the flue.
They sell compressed air in a can that is used to clear clogged drains you could try that. Find the other end if possible, because freezing is a common problem when they drain to the outside. If frozen then you would need electric pipe wrap to prevent it.
