Good morning. In an attempt to replace the anode rod as is recommended on a new to me 2016 rp179, it has rusted pretty significantly into the threads. I doubt it’s ever been touched. After wd-40 soaking, it won’t budge using my socket wrench. Is this water heater sturdy enough to handle the impact wrench? Or are there other suggestions? Thanks!

Spray it with PB Blaster (forget wd40) and wait a couple of days, then try again. Use a breaker bar and apply steady pressure on it while gently tapping the socket with a hammer. Might take a couple of tries. Should come off.

Put a 2’ cheater/pull bar on the end of your socket wrench. This usually will do the trick.you can use a piece of pipe if you don’t have a pull bar.when you replace the anode, use a couple of wraps of teflon tape to eliminate leaks and also stop rusty threads

Mine seems pretty sturdy, but I wouldn't use an impact wrench.  Try another penetrant oil (made for that) and a long wrench with gentle steady pressure.  Vibration from tapping on the hex head while spraying penetrant sometimes helps.  

I found anodes at Ace Hardware and Walmart for a good price.

According to the "Project Farm" Liquid Wrench seems to be one of the best penetrating oil.
Here's the comparison of different penetrating oils:  https://www.youtube.com/watch?v=xUEob2oAKVs

Thanks for the advice. I went w cheater on the breaker bar, with liquid wrench, not wd40, and it broke loose. Replaced the rod using Teflon tape, all back together now. The one that came out was gone just to the size of a welding rod! Definitely time for a new one! Again, thanks…  love this forum!

If there is any magnesium left on the rod at all its still doing its job. Check it annually. Usually you'll see some rod at the base of the anode before the magnesium toward the tip is consumed. If it looks like that it's still working.

I don't buy this evaluation at all. First he torqued the nuts to 100 ftlbs. Then he corroded them with some type if oxidizing agent, after which the torque to remove them only went up a few 10s of ftlbs. Then some of the penetrants brought removal torque down below the original tightening torque.
Obviously, the threads didn't get very much corrosion on them. We all know that removal torque on very rusted bolts is much much much higher than the tightening torque was.

He also didn't leave the penetrants on long enough, my experience is that it significantly helps to allow them to remain on there for a day or two.

I've used liquid wrench a lot in the past but PB blaster has if beat by far in my experience in the real world. WD40 is pretty much useless

One result does agree with my experience. The flame wrench works great. And verbal threats are good too.

Why don't you do your own experiment with various penetrating oils and tell us which is best.  Maybe you could make a video and post it to YouTube.

The video was kind of interesting, but even he admitted it wasn't very scientific.  I came away with the impression that for practical purposes it doesn't matter all that much which product you use.

Ever since I got a 60v impact wrench, I don't care too much about this kind of stuff anymore.  Now, maybe on something relatively flimsy, like a water heater, I don['t know.  I'm not sure, but it seems like careful use of an impact wrench shouldn't be more likely to cause damage than using a cheater bar.  It is certainly much easier!  Of course it's not a tool everyone has.
