Anode rod removal

Any sugestions on removing annode rod on 2012 Roo19 without damaging it? It is on from factory extremely tight and rusted.

I am afraid to apply too much pressure on the wrench for fear it might do damage. I also applied wd-40 and still stuck.

Also, if I decide not to try to get it off, is there any down side to leaving it on all winter? How can I make sure iWH is drained if I don't remove it? Do I just release pressure valve? I have already bypassed and winterized the lines, but want to be sure there is no water left in heater.
Thanks

WD 40 stands for Water Displacement formula attempt #40. It is not penetrating oil. Get a good grade PENETRATING oil. soak the connection leave overnight soak again. Using the correct size socket remove the Anode. You might find an impact gun makes the job easy. Possibly you can rent one at a tool rental store or even places like Home Depot.

On the subject of leaving it. The longer it stay's in the harder it will be to remove. Now you have the same job, more difficult at a later time. Eventually the anode has to be replaced. If you don't the HW tank will corrode out and you will be faced with the expense of replacing the tank. Good luck!

You have to remove anode rod to drain the tank.
Put some muscle behind it.
1/2" breaker bar will get it loose.
Little bit of heat from a propane torch might help.

Try tapping the bolt "lightly" with a hammer. Sometimes that will break free the rust on the threads.

The only easy way to drain the hot water tank is by removing that bolt. If you don't drain the tank it will be damaged when the water freezes.

It's a NPT fitting, 3/4" I think. It has to have pipe thread sealant or teflon tape or it would have leaked. The fact that it has either, will make removal easier...you just have to show it who's boss!

I've taken pipe thread fittings apart that have been 20+ years old...shouldn't be a problem with a 1 year old WH. A 6 point socket of the proper size is the only thing that you should use.

I'm beginning to think I am the only one that removes mine after every trip. It's always how I have drained the water heater.

I guess on the positive side.... I have never had a rusted and stuck rod.

Nope not alone !
Drain mine after each use.

No thread tape
No thread sealant

No leak.

The number one thing to do is use the correct size socket. If it is corroded in you have a problem because the sole purpose of the anode is to prevent corrosion of the iron parts of the water heater.

Always use teflon tape or teflon pipe dope to reinstall your new one.

It's always a good idea to replace your anode rod after every season. They are designed to corrode so the water doesn't corrode the tank.

You can, but I think it would be a waste of money. They don't require replacing until there is no material left on the rod. I had my last TT 8 years and replaced the anode rod once. Depending on your water conditions you may have to replace more often, or even less often.
