 If you've got a leak around that stack pipe, I'm 99% sure. She was asking about she had some flex tape or flex seal put around it and how to remove it so they can fix it. Oh, okay. Sharp knife, sharp putty knife, something along those lines. You know, maybe a little heat, but I would try a knife first. But those donuts might go over your flex seal also, so that's what I'd check first.
