I decided to do a little preventative maintenance on my water heater today......glad I did as I guess I didn't understand the life of an anode rod
This poor guy had sacrificed about as much as he had over the last 18 months. I'll be checking every 6 months or so from now on.
Having removed the rod, I spent a good 10 minutes flushing the tank, and was amazed how much crud came out of it.
