Hello. Does anyone know why they do not install "Annodes" in Galvanized Well Tanks? The next New Galvanized Tank I purchase, I Will Install one. I think you can buy one for a hot water heater for about 20 bucks. Even if this only adds a couple of years of life to the Tank, its worth it, since a 315 gallon tank goes for a couple Grand. Any thoughts on this?

Thanks
