Hi Gang, My pellet stove pipe leaks. When I fire up the stove and do the flashlight test, it leaks from several spots in my pipe. I continue to put sealant all over the seams and connection points, but I just cant get it to seal tight. I don't have very much pipe. Its 4 feet tall and then a 90 degree bend straight through the wall. Will new pipe fix the problem? Thanks All!
