Does it matter the rod doesn't snug down as originally as long as it doesn't leak?

In one search it shows someone putting six gallons of vinegar in the tank and letting it sit overnight. Something tells me that is probably overkill, yet that is not unlike the instructions for my annual maintenance for an on-demand water heater I have in a room over my garage.
Hi: Rossue... I use a wooden handle wire brush. A few strokes with the threads and deposits are gone. Alf

Hey Alf- yeah, couldn't find mine and tried a never-used battery terminal brush. Didn't seem to have much effect so will go down to Ace & get the wood handled brass wire brush. Thanks.

Suburban recommends leaving the anode rod out during storage.

I don't think my anode ever went in further than this.

Just a thought besides the Teflon tape what about using a little white lithium grease on threads ? Pat

Found the wood handled brass wire brush and it worked very well with some vinegar. Snugged it up and isn't leaking so will check that anode again in about six months to see how it's doing.

Hi: Rossue... Better not be leaking... You'd get a visit from the water "Police"!!! Alf

WHAT? A $15 anode replacement (in your maintenance kit ) if it fails... your're willing to be without hot water? NOT me, YMMV

If your anode "fails" you still have hot water. It is only there to be eaten away, instead of the tank being eaten away. You won't notice.

From Wikipedia, the free encyclopedia

A galvanic anode is the main component of a galvanic cathodic protection (CP) system used to protect buried or submerged metal structures from corrosion.
They are made from a metal alloy with a more "active" voltage (more negative reduction potential / more positive electrochemical potential) than the metal of the structure. The difference in potential between the two metals means that the galvanic anode corrodes, so that the anode material is consumed in preference to the structure.
The loss (or sacrifice) of the anode material gives rise to the alternative name of sacrificial anode.

It really can't fail, it can only wear out, and my annual winterizing gives me the chance to see how much wear it has. In my 19, I changed it after 5 years, though pretty sure I could have got at least another year.

Frankly, I would be shocked to see more than a few that carry one, plus the socket required to change it out. Who actually checks it while on the road, that is the only way to tell if it is worn out at all. As baglo pointed out, the water heater will work fine without it, and will suffer very little for short term use without one plus you would not be without hot water.

Who here ever checked the ones in their water tanks at home? That, and not flushing annually cause most of the fails of a storage tank type water heater.

Besides, isn't something like this the reason to carry a zero balance credit card?
