Who played Ralph buddy Ed Norton who worked in the sewers?

You're thinking of the character "Ed Norton" played by Art Carney in the classic television sitcom "The Honeymooners".

He was Ralph Kramden's best friend and neighbor, and the show often played on their contrasting personalities - Ralph's loud and impulsive nature compared to Ed's more cautious and thoughtful approach.

While Ed's job isn't explicitly stated as being a sewer worker, he often complained about the unsavory aspects of his work, which implied a job involving waste disposal or similar.
