    Just spent some time reading the installation manual for my furnace model, it does appear it's not installed properly in terms of vent/exhaust pipe sloping. The intake pipe has a slight slope into the furnace, I couldn't measure the slope since there were so many things installed there but definitely does not look like the picture in the installation manual. But the exhaust pipe is totally level with a large sag in the middle because of no support across 6.x feet distance. This could totally resolve the issue if addressed. Now it's time to find the right contractor.

    Yeah, that looks like it passed inspection! I'd imagine that sag in the flue pipe is from about 5 gallons of water sitting in the pipe, can you take more photos of the install? As far as the home warranty, I believe if it's done wrong the contractors on the hook even if it took you 20 years to find it

    What is hooked up to the top of the drain T going into the furnace.

    The furnace drain T is supposed to be open at the top with noting else hooked up to it, to act as a vent. Also I hate vinyl tubing for drain lines, they tend to clog easily.

    Wow your install just keeps getting better.

    Looks like u have room to push up the dip in the pipe and see id water come out of the drain, usually on a problem like that i could hear the sloshing or the change in flow from the outside when units running, not always though.

    Here are some more pictures, I think tomorrow I will contact the builder. They have top notch customer service, will see what they say. I'll ask about inspection. Also I'm going to get a snake camera and see if there is anything in that exhaust pipe sag. The central humidifier was installed by another local HVAC contractor, not the builder.

    Wow just keeps getting better.

    Does anyone in your area take pride in their work.

    Ok your humidifier drain must not be T d into the furnace drain.
    Your humidistat is too close to the humidifier- I believe it is supposed to be installed atleast 12 inches above/before the humidifier itself.

    Did I mention how much I hate vinyl tubing for drains. All drains should be run in 3/4 inch schedule 40 pvc.

    Did the person installing the humidifier not have a tubing cutter, looks like 20ft of coiled -/4 inch plastic tubing going to the humidifier, hope the tubing holds up, I only use copper to humidifiers. Wow I have seen kids do better installs.

    Whats the tan box on the wall with the drain on it, hopefully a trap primer for the floor drain. Maybe put a water sensor alarm by the drain if that is the low spot in house.
