WOW the crud that came out of HW tank
Winterized today and after emptying the Hot Water tank,(and bypassing it) decided to flush it with my thin spray hose attachment
Minerals and chunks just kept coming out,I mean BIG chunks like small rocks I assume fell off of the anode rod
I recommend flushing.

I didn't have a way to flush mine at the camper lot so will have to do it in the spring. Judging from my massively corroded anode rod, I expect lots of junk to come out.

Flushed for the first time this Fall and sounds like mine was similar to your discharge. Previous owner didn't use a lot (2010 - 10K miles) and never flushed the tank. That being said, the anode rode looked almost new. Will be an annual event for us now!

My TT only saw half a season b/c it was new. Still when I pulled my anode rod to winterize it was nearly eaten through at the base (threads). Rest of the rod looked relatively good. Guess I'll be getting a new one in the spring.

Pulled my anode rod to winterize today and got this black tube flowing out. Looks like a small amount of pipe dope on the broken part, hope it does not affect hot water operation next month.

I've noticed my last 6 or so trips that my hot water pressure isn't great especially in the shower (not a full spray and a lot of dribble)
I got to wonder if all the debris I got out of the tank may have been hindering the outflow?

If it's only worn at the base, then it's still got a lot of life left.

If we aren't planning to use the MH for a while I always drain and flush the HW tank. It also saves on the anode rod. I have 3 years on the Suburban anode rod and it is at about the 50% level.

I used a threaded/slip fit connector and a 6" pc of PVC to make an adapter that screws into the WH (once Anode is removed) You can slide a clean out wand inside it and flush the WH. The adapter keeps the crud that flushes out off the side of the RV.

It's likely that the "crud" that flushes out of the water heater is minerals from hard water rather than pieces of the anode rod. The rod probably doesn't erode in "chucks". They can look terrible, but still function just fine.
Put un-softened tap water in a dark-colored pan or kettle, heat it until much of the water has evaporated, then look at the walls of the kettle; they'll be coated with gray/white minerals (largely calcium and magnesium), the same stuff that comes out of the water heater. Don't panic; we all need those minerals for good health.

Thanks for the education! I didn't know that! I thought it eroded equally across the length. Saved me some $!

You might find some crud inside the shower tubing and behind (or inside) the spray head. I did - on a new unit! Some construction debris worked its way right up to the end. I wonder how much didn't.

I assume that piece is the cold water inlet pipe that deposits the cold water at the bottom of the tank so you can draw hot water from the top. With that missing, you'll get immediate mixing of cold and hot so the water you draw won't be as hot as it should be. I had the same issue with my home water heater and symptom was lukewarm "hot" water.

That's a good point!
When I removed the small screen bowl on the water pump to complete draining my system I found a small Plastic zip tie

I am guessing you may need to take the shower head apart and clean it,,, or replace it ??? Probably should also check faucet screens !!!

Depending on the time yours was built it may not have an Anode rod. We used a suburban water heater that did have one but switched at some point to an Atwood aluminum tank water heater eliminating the need for an anode rod.

Good News, your home water has the same crud. And an anode. Your home water could use the same service. Just say'in.

You do have a point I just connect a hose and run it out the back door. At least check anode. That is the life of a water heater.
