I drain and flush my tanks every year due to hard well water. I was changing the anode every 4 years. Mine were getting eaten up really bad. Last month, one anode was no longer connect to the rod end cap. These titanium units are remarkable. Water quality has improved greatly.
We have well water also
I havent touched my Rheem water heater since 1999 when the house was built
Installed myself a water softener around 2005
Well actually i did , i raised the temp output on the water heater
I dont even know what an anode was until i read this thread
There i just screwed myself
