Winterizing the hot water heater

I know to turn the bypass valves so no antifreeze goes into the hot water heater but should I leave the drain plug out during the winter?

I do but then again I have a screen over the intake to keep the small critters out. You can put it back if you want. I like to run some water though it in the summer to flush it so if the plug is out it's one less step.

I used to leave mine out until I found spider webs in the hole. Now I drain and replace the anode.

If your heater is like mine, the lower line sits just a tad below the tank, so water tends to gather at the backside of the bypass valve. Discovered that this year after I blew out the lines, but didn't fill the lines with anti-freeze right away. Had a cold snap sooner than expected. I found the valves iced up, so I ran the furnace and brought in a second heater, then ran antifreeze through the faucets.



What I do now is when running the AF through, when finished I crack the lower bypass valve for a moment to get a little AF behind the valve to keep the water behind it from freezing too hard. In spring once the lines are flushed out, then open the lower bypass and flush the tanks once more before putting the plug back in.



Even blowing the lines, some water finds it's way back in at the low spots, so better safe than sorry.
