Rheem water heater model 21v40-7
I have a Rheem Hot Water Heater 40 gallon model 21V40-7 that was installed in February, 1993. Except for it making some noise the other night which I was told could have been from sediment or air, it still works fine.
Some techs have recommended I replace it because it is already in use over 20 years. I know the newer ones are not as good as the old.
Do you think I should replace it before it might leak all over the basement floor or might it still have more life? Thanks for any suggestions and reasons.
