“Not real happy with these pipes. Second pellet stove I install no problems 4 years ago with 3 “ galvanized. I stepped up to 4 inch black smoke out of lots of joints. I had to place ugly black foil tape on each seam. Looks terrible but no more seepage right away. Tolerances we’re obviously way off. This review page is stuck on five stars. SMH I give it .5 a star. As expensive as this tubing is it should work flawlessly.”
