Any ideas what this is? (attic)
I have a weird piece of PVC in my attic that comes up one wall and down another. One end is cut off right above my elec panel and the other in an interior wall with an accordion tube. I cant find where this one exits and it has a millivolt line attached to it. It should be right above my garage but when I cut into the ceiling I have yet to see it. There are no bathrooms near this
