Water Leaking Furnace Heat On
Hello everyone, I recently notice that water was starting to form around my Furnace in the basement and this is when I have the heat on. I'm not sure how old the furnace is but I think it's pretty new. During the summer when we had the air conditioning on it never leaked any water and for the most of this winter It has not leaked until recently. I did a visual inspection of the drain pipes but I do not think it is leaking from a cracked pipe. Any ideas of what maybe going on and I thank you in advance.:)

Furnace Leaking

The roof is new. I think it's where the water drains out of the pipes. And I am not sure what a 90plus furnace is. Here is some pics of the furnace leaking downstairs.

90 plus furnace uses pvc pipe instead of metal flue pipe :thumbsup:

Looks like the condensate line has a leaking fitting. Make sure they glued the fittings, sometimes the installers get sloppy. Other than that it could be an improperly pitched flue pipe or the furnace is not level and the condensate is running out the exchanger instead of out the drain.

Furnace Leaking
Yes it is a 90 plus furnace. I will check out the drain lines to see if the fittings are good and glued. Do you think it is a good idea to open the furnace up and see If I can see in to see if the exchanger is the source? Again thank you in advance.

sure you can open the front cover of furnace to make sure controls and board are not getting wet,you wont be able to check heat exchanger just the drains from it and inducer motor and maybe bottem of flue pipe depending on plumbing :thumbsup:

We had the same problemm on our high efficiency furnace. The furnace company came out and opened the front door of furnace. The leak occurred at the joint between the furnace and the small plastic drain pipe. He just tightened it up and all was good.

It would have been an easy DIY thing, but the furnace was still under the installation warranty so it didn't cost me anything for 3 minutes of this person's time.
