Water heater drain valve

I have a suburban hot water heater on my 2015 Cherokee 274dbh. Has anyone seen or put a drain valve that somehow attaches to the anode rod? It would most likely have to be an anode rod with a drain valve built into it. Any suggestions appreciated. Thanks.

It's funny (weird), but so far as I'm aware:

Camco makes an anode rod with drain for Atwood HWH's, but Atwood HWH's don't NEED an anode (the tank's aluminum).

But, they DON'T make an anode rod with drain for Suburban HWH's, which DO need anodes!. So what's up with that?

Any "Jury Riged/Cobbed Up" A-Rod/Drain Valve I have seen requires a "Reducing Bushing" that further allows More "White Crud Buildup"in bottom of tank! Youroo!!

NORTHWEST LEISURE ANODE KIT UNIVERSAL TSA-200
Replaced mine recently but watched you tube vids on this subject. This one I have posted, with the drain, did not perform as well, as the stock anodes, over time. Here is a you tube link showing the two different anodes. BTW I went with the stock anode ( no drain)

That thing looks like it would take quite a while to drain through that little slot.

I'd say that "most" of us don't drain the water heater except at the end of the season, when you should be removing the anode anyway for inspection; so the drain doesn't seem like it's worth having.

If you're one of those folks who drain after every trip, then I guess it might be helpful. But as mentioned above, if using the drain, you aren't going to be flushing much, if any, of the crud out with the drain valve.

How long would you leave the water in the tank? If I know I am not camping for two weeks or more I will drain the tank.

Yea agreed. I don't drain often either and judging from the video that short anode doesn't seem to be reacting enough anyway.

I fill it first trip in the spring and drain it after last trip in the fall. Could be 2-6 weeks between trips over the summer, depending on what's going on in "my other life."

Water sits in my home water heater for 1-2 weeks while I'm gone. I don't drain that one, either. And I never flush it (like most of us, I'd bet!), although I probably should; might help it last more than 8-10 years.

Key the Twilight Zone music.

You responded to my post before I posted it. How'd that happen?

I made the mistake of not reading my manuals thoroughly and left my anode go 3 yrs. It was 95% gone when I finally changed it and all kinds of white crap came out of the tank. So your right about being able to flush scale out of the tank through a bigger hole. Or whoever posted that.
