While visiting a job site yesterday, I came across this repair job on a hot water flue. (Please note that we did not make this repair, it was done previous to our arrival on the job.) The repair is an old Folgers coffee can clamped around a furnace flue pipe. Probably not the best way to make a repair as it will most likely allow some flue gas to escape into the basement. It did bring back some memories of my own father and some of the repairs he would make around our old house I grew up in.
