There was no sewer gas smell to it. I put my nose right up to it. A passive radon system sounds right. I would have never thought of that. Thanks a lot for your replies!!

Hello everyone, I did an inspection today on a 2005 house. In the basement, toward the front of the house I found this pipe sticking up from the floor. It is PVC and it is tee'd into another pipe running under the floor. I have no idea why it is there. There is wet fiberglass sitting at the bottom so I know water is flowing through it. Any help would be appreciated. I feel like a dummy posting this but I just can't seem to connect the dots. Click to Enlarge 28.65 KB

I have a question. I inspected a new house for the home owner that had the grounds and neutrals double tapped. As I was pointing this out he mentioned to me that he has had issues with certain breakers that would trip. He said that one of them would trip at 9:15 PM every night. He had the builder send over his electrician who didn’t find anything wrong. He also had two other electricians come. One of them told him that it was the AFCI and that they are sensitive but tends to act normal after a few months. The electrician changed the breaker and after a while the homeowner said it has not happened for a couple of months. This is a Siemens panel. As I noted earlier, the grounds and neutrals are tapped together within the same lug hole. Would this cause the problem he is having? I did do some research but I am unable to find an actual wiring schematic or any info about this particular situation. The AFCI's neutral were in their own lug hole. I am just wondering if the other ground and neutral double taps could affect this.
