currently finishing report and have to ask. I do not believe this flex pipe is adequate for vent connector from the mid eff furnace…aside from the fact that it is poorly fastened and probably spewing CO into the house. Soon as I say with authority ‘there cant be a dang flex pipe connector’ some body comes along and proclaims 'oh shoot yeah, they make a special flex pipe for difficult vent connections…you didn’t know that?? so I inquire earnestly.
