Rheem Marathon, no anode rod
I am almost positive that my hot water heater is going south(12+yrs old) and it is the culprit of creating H2S on the hot water side that damage my copper coils in my A/C unit.
I have extrmely hard water and no softener yet, working on it.
I looked at the rheem marathon hot water heater that is made from a blow molded,polybuthene tank that is corrosion free and because it is plastic it als o eliminates the need of an anode rod.
These units are pricey and I was wondering if anybody had any experience with these hot water heaters before I buy and install one
