In a casual conversation with a plumber, I was told the Bradford Whites water heaters with a black ‘rubber’ flexible flues were ‘illegal’. I was wondering if this was an actual recall on the flue piping, or were the original ones ‘grandfathered’ till end of life? The water heaters, or the clients.
I’m having a difficult time finding information, probably since these were used in the early 90’s, or just not true. Little help?
