That could be true but around here you never take the condensate from the furnace directly to the outside but to a regular drain line inside to prevent that type thing and if that drain freezes you will know because the entire homes plumbing system will back up. LOL

Some city codes will not let you tie in with sewer lines and remember city code rules.

Do not live in the city if you know what's good for you.

Hi Folks:
Just got back to see all these discusion,Thanks for the help. I will check all these, living our condensate drain in side the basement sump pump well. And sump pump never need to work because remain dry because nothing to pump out.

But I noticed there are some green (like copper sediment) liquid dried out in a drain spout of natural gas line, do you folks know what is it? IF this has anything to do with the Furnace running its own schedule not following thermostat?

We appreciate very much for these helpful suggestion, and look forward to your valuable suggestions.
Thanks,

Folks, just I want follow through the things I have done since my last post.
1. Take Jump off the R & W and put back the orginila red amnd white wire back in the connection spots.
2. Try clean up although there very little clean.

3. Squeeze the condenstae drain pipe and raise a little, and suddenly gush of water starts draing in the drain pipe going into drain hole. I thing about a gallon of water darined.

4. Close the panels.
5. Turn on the power to the furnace and heat came out and house is in comfortable level now.

5. I think this has fixed the problem. Thanks God.

Thanks so mcuh! Have awonderful weekend.
