There can be other factors in a water heater’s demise beside the anode and I should run down those with you, but I totally agree that you need to test it, and I do have a set of instructions for that. Could you e-mail me so that I can attach them, as well as discuss this further? This is not normal. I’ve sold several thousand of these and it’s very rare to have a tank fail.
Just for the edification of everybody here, though, I’ll add a little more. I wouldn’t blame Rheem especially, but all the manufacturers expect to have some heaters fail due to defect. They call them leakers, and it’s one reason they offer a warranty.
I fully assume that every powered anode is going into a water heater where the water is softened to zero, because most softening techs won’t go to the trouble of adding plumbing to mix in some unsoftened water. They have also told me directly that they think zero is a good thing.
It’s now seven hours after I first posted this and having thought some more, I decided I ought to elaborate here rather than privately by e-mail. My guess is that the third water heater was indeed a leaker because any water heater, even without any anode at all, would last longer than three months.
That said, I’d like you to test for pressure and thermal expansion, because the middle water heater should have lasted a lot longer than one year. You can do that by using the Tanklets link on the left side of the Tank topics index and then clicking on Temperature/Pressure Relief Valves. The test is fairly easy to make. Pressure is a hidden killer of water heaters that nobody usually thinks about.
