I called the homeowner asked them to look at the plastic pipe in basement out of furnace they said it had letters on it PVC.
thats why i deleted the post after they looked.
i was not shore had a few calls today just had that one stuck in my head cause of the fisco in the top compartment with nothing going into it and it just sucking in the basement air thought it should be piped to outside but did not know, cause thats how it was installed.
Like everybody else is saying the PVC has to go.
It could not have lasted this long if it hasn't been replaced previously.

Luck
