The metal base rod of my anode rod is showing near the plug, but the rest of the rod still has probably 80% of the anode left.....plenty more years of service. Like Arn, I will probably replace when it is somewhere 75% gone.

This thread has been very helpful. I pulled the anode last night, flushed the HWH, then reinstated with telfon tape. Looks like I got plenty of zinc left for a while. Thanks everyone. Heading out for the weekend. later,
