        We live in a throwout society. Hot water tank companies want you to be replacing them about as long as the warranty lasts. Last I heard, although I haven't done it because I'm not a service plumber nor do I do much in the way of hot water tank RE and RE's is those magnesium anodes are very difficult to replace now a days supposedly (maybe you guys can fill me in a bit more) - gee I wonder why? If word ever got out that putting in a better one, or replacing your aged anode would help extend the life of your tank god only knows what would happen to the hot water tank companies.

          I've heard that about the anode. A guy I know who is a rheem rep also told me the tank liners about about half as thick as 20 years ago.

            Water temp is also a factor. The corrosion rate (expressed in lbs/kgs of metal lost per year) doubles for every 10 degrees over 140. If a large area of metal is exposed, it will last a while. If there is a pinhole or crack in the liner, it will drill through it in no time once the anodes are gone if the piping to the ground is all metal or if the tank is bonded to the electrical ground.

              most of the hot water heaters in our area usually are pushing 30 to 40 years, before replacement, and very few leaks (have never seen one replaced do to leaks), I put mine in early 1980's and the one in my folks house in town was installed in 1976, I have one in the barn that is I am sure a 1960's manufacture, mineral build up in the tanks is the normal reason that there replaced or for life style changes, (need of more hot water),

                on some newer heaters the anode hangs off the hot (left) side nipple. you will see it if you ever have a reverse install and have to swap the dip tube side. if its a heater with FIP connections (no pre installed nipples) its under the top sheet metal pannel. i think they try to hide them

                as far as brands go anymore its a joke......
                A.O SMITH, RELIANCE, WHIRLPOOL, APOLLO, STATE, MAYTAG, AMERICAN, GSW and JOHN WOOD are all made by the same company.

                Rheem, Ruud and RICHMOND are also the same company

                I think bradford white is a single company but i could be wrong

                around here they last about 10 years

                  Years ago I swithched to bradfords because A.O. Smith was having problems. Now because of this thread I have gone back out to research and have found out that a local plumbing supply house has stopped carrying bradford white because of problems

                    We have had a lot of prevailing winds out of the east this winter, which is rare. Since the combustion chamber is sealed on the the new models, the draft blows out the pilot, it can't just blow thru anymore. I have had a lot of calls to relight pilots. It's hard to make people understand these new water heaters are so much more touchy, plus they cost twice as much. Lots of unhappy campers. Tankless is looking better and better.

                      sounds like a lot of easy service calls
