Huh? I work at a 20 year old apartment complex and we still have a shitton of the original water heaters. Hell the one in my own house is 25 years old, I've been here 16 and the only issue I've ever had with it is I had to re-light the pilot light one time. That must be what you tell your customers in order to get them to buy a water heater that they don't really need.
