Water heater plug?

Winterizing the motorhome today and drained the water heater. Does this need to be replaced?

That is the anode doing its job. It's designed to be sacrificial, you have at least another season before i would be concerned

For what little they cost and seeing it's better then half gone, replace it.

Thanks Rickim

We have lots of iron in our water, the previous owner must have had lots of lime.

I think maybe I will but I'll wait until next spring when I get it out of storage.

Cleanup the threads and reinstall.
If you don't plan to use for the winter leave the tank empty and this way you have time to buy a new one for next season of camping.
Online they run about $15-$20 a piece but if you buy a few you get a better deal.
I bought 6 on eBay for $43 and free shipping and not tax.

Here is two for $30 and free shipping on EBay.... LINK

Ditto.

I would just cut the rod off and use only the threaded part hand tight in the threads with some pipe tape to keep the rust to a minimum.

Couple questions. Where is the HWH drain plug on the GT 378 and how do I get to the Anode rod?

Another good reason to replace that anode is that small fragments from an old one can clog your screens on the toilet cold water supply line.

I replace mine annually. Probably not necessary, but cheap peace of mind.

You need to explain how water from your hot water heater is going to get to the cold water line for your toilet.

If you yappers had been around here long enough you would know. Quite a few of us have had it happen. The small particles swirl around as cold water enters the heater. The anti reverse valve is open while cold water enters. Over time many of these small particles can migrate to the filter at the cold water line to the toilet and completely block it. They can also accumulate in the diffuser screens on the water faucets. In my case the anode had completely disintegrated in just one year. I flushed the water heater and a huge amount scale like particles flushed out. It only takes a few to clog the cold water valve partially open. Replacing the anode annually takes care of the problem.

By the way, you seem to have lost your way. Trailers are in another forum.

I think that it is wise no matter if you own MH, TT or 5er. All the units have problems and people's in site is great on plumbing. The plumbing is all pretty much the same. MH are just fancier controls. You have a suburban WH. correct might be 10 gal or 6 gal. makes no difference unless it's instant hot. I didn't know that if you do not own a Georgetown or another MH you can't learn something by asking a question on a subject that is in line with the post because you don't own a MH.... And I disagree with you with all do respect, even replacing an anode annually you will still have deposits in your tank off the rod. That's because it doing what it suppose to do.....

I've owned 2 f350's and two 5vers, the last a 37' Montana. And yes there are similarities and of course asking questions is totally reasonable. Yukking it up before you know the answer is ignorance. Respect works both ways. When somebody wants to be a smart ass they can expect the same in return. Your response deserves respect and yes the anode does begin to shed particles relatively soon. Its supposed to. The key point is that an anode can severely disintegrate in a single season and due to the swirling action in a small tank the particles can migrate. In a large home sized tank particles like sand or whatever can sink to the bottom and it can take years for them to cause any problems. Removing the anode and flushing the water heater out is good preventative maintenance. But to each his own. I simply pointed out what can happen in a single season and got some snide remarks in return. Thank you for your comments.
