Does my anode bar need replacing?

Hey guys. So I was winterizing my new trailer for the first time this year and when I pulled the water heater drain plug I found it was this long bar (which I later researched to find out was an anode bar). I never had this in my last trailer so have never dealt with it.


My question is pretty simple, how far gone is my anode bar? Is this bad? I'm not sure how often they need replacing, I can Google around and find info about house water heaters but the info on RV water heaters is scarce.


EDIT: I thought I was adding a picture but I guess not, trying to figure out how to put it in my album here and link to it.


EDIT 2: Here goes trying...







Thanks!

Your anode rod (not bar) that you have pictured is good to go for awhile. No need to replace.

That anode rod is as good as new. Keep on trucking... or send it to me and I’ll use it!

Be careful wrt the rust on the threads. Bar still has a lot of life left.

Since you have a Suburban water heater, these videos may help:

Suburban Water Heater Video Guides

You want to replace the anode rod when it's 75% percent or more
consumed, as per this chart

For my own piece of mind, I replace my anode rod every year after all of the water is drained from the tank and the unit is winterized. It is then ready for the upcoming year with a now rod. I'd rather be safe than sorry.

I do a plumbers Teflon tape wrap around the threads. Works great.
As mentioned, there is still a lot of life left in the anode.

Still in good shape, I always used anti-seize on the threads so it would not get stuck.

Be careful with anti-seize compounds. Many of them are lead/graphite based. Just sayin'.

I'm with you. I replace it once a year when I flush the tank. They are inexpensive and, as you said, "better safe than sorry".
