Hello

Please see picture. I am getting water leaking from where the pvc exhaust exits the top of the furnace - pools along flange and leaks to floor.

The inside of the unit is dry. The exhaust fan pipe drain is not clogged. Is this as simple as maybe a critter or some junk is in my exhaust pipe causing it to accumulate excessive moisture.?

Also, how do I disconnect the pipe flange? Is that done from the inside of the unit?

thanks to all!

A blockage in the venting causes that to occur with dryers, the humid air condensing when it cools and then pooling at the lowest point. It can also happen when a vent is just too long.

I would suggest checking and/or cleaning the vent all the way to the outdoors.

I'm afraid I do not know that.

Yeah, that’s the one trick I need to figure out. I don’t want to cyst the pvc and re-glue it with a connecting piece ...

Anyone else know how to disconnect the vertical exhaust PVC vent tube from the top of the furnace?

Thanks!
