winterizing - hot water heater question

I am winterizing our Flagstaff HW27SC for the first time today. I pulled the drain plug/anode rod from the hot water heater to drain the tank and didn't know if I should leave the anode rod out for the winter or put back in? Any advice would be appreciated! Other than that, everything went smooth.

I put mine back in. If you don't, be sure to cover the hole so nothing can crawl in.

Having just done mine for the VERY FIRST TIME, I am now an expert. Thus, I say do as I did and put it back in but sort of loosely.

(Know what an expert is? An "Ex" is a has-been. A "Spert" is a drip under pressure".)

Yeah, screw it back in loosely and rinse the tank with fresh water before the start of the next season.
Depending on how hard your water is you may want to consider filling the HWT with vinegar and let it sit overnight to dissolve mineral deposits and then thoroughly flush it out. Just don't do this with a brand new anode rod installed.

Tighten it back up.... if you put it in loosely... you will forget and have a mess when you fill up the water tank.... if you want to hose out the water heater next spring when it is empty... then loosen it and take it out.....

From my reading of the forum for the past 5 years, I'd say it's about a 50/50 split on folks leaving it out or putting it back in. So my recommendation is: do whichever makes you feel good.

But if you leave it out, make sure to cover it so bugs don't get in, as mentioned above.

Put it back in and tighten it up.

You already have the tools right there from removing it so you won't need to drag them back out next spring.

I have trouble remembering what happened last week let alone last year (come spring) so why not just finish the job you started.

There are no benefits to leaving it out. It will just stick in there in mid air until the point you dewinterize and open it back up to water.

If there were any benefits to leaving it out, it would come that way from the water heater manufacturer.

Clean threads on tank and anode, wrap anode rod threads with new teflon tape and screw back in. If gas and electic heater, good to be sure power and breaker are both off. You can tighten anode when you change bypass valve settings next year.

Except when you were packing up and left your DW behind at the CG.

You can get a plastic plug to keep dirt/critters out. Just remember to reinstall the anode rod in the spring.

Just screw it in loosely and put a tag on the outside to remind yourself.

That was just a suggestion, I just drain it and re-tape the anode and tighten it up.
