There are some maintenance things we should do and I think most of us do regularly. Change the oil in our vehicles, change the air filters in our HVAC, etc.

Then there are the other things that we might should do, but probably don't. Things like brush after every meal, change our wiper blades regularly, clean your gutters quarterly and replace the anode rod in our hot water heaters.

I'm good at the first list, not so much the second. I can honestly say in all the years I've done maintenance around our houses, I've never replaced an anode rod. I'm just curious, how many here actually change theirs on a regular basis?
