hello all....I have a Bradford White water heater. It was new in 2003. It's 50 gallons, natural gas fired with direct vent. Within the past couple of months, we have to adjust the water continually to keep it hot, even in the first shower of the day. We are on public water and i did a flush for any sediment last year and there wasn't any. I know on an electric that the elements can be replaced, but I'm not sure of the maintenance on a gas heater. Can the burners go? Any suggestions?
Thanks!!!
