Seriously, I'm wondering why they're all failing in the same year.
Should be easy to figure out. The label you showed indicated a 5-year warranty, which means only one anode rod. If the heater is much older than 6 years (manufacture date should also be on the label) and you didn't change the rod, then that's why it failed. You can look at the failure date minus the manufacture date and get a rough idea of what the longevity of the rod is under your water conditions. All of your other water heaters in the area will also fail at the same point in time if you don't change the rods.
