Well, I recently began to get a nagging feeling, more subconscious than anything, that maybe, maybe I should take a look at that anode. After all, as expensive as these specialty water heaters are and with an aluminum tank, I really did not want it to go without protection.
Above is the anode as it looked just before it was installed. And below is its current state... pretty good in fact.
But in any case, the water heater should now be good for another five years at least. I'll pull this anode in 2021.
Do you change the zinc in your household water heater? You should...
