I don't remember what brand it was but I got it from Chimney Liner Depot about 6 years ago. They said only use a plastic brush on it which I did but it is coming apart inside. I snapped some pics. Think this thing is ok ?
If not do I need a flex liner ? Why can't I just use Black Pipe ? My chimney is about 20 ft and most of it is inside the house. Only last 3-4 ft is exposed so I never insulated it. It always worked fine .
