leave in or keep out water heater plug winterizing?
I tried searching but a simple question. after draining HWH do you replace the plug or leave it open? Thank you in advance

I put in a stubby 1/4 turn brass ball valve in the drain of three different rigs, works real slick
How do you keep the rigs from rusting without the anode?
Even if it isn't a Suburban that uses an anode rod (Atwood doesn't)
That drain valve will drain water but leaves scale/crud behind cause it can't flow out that small diameter opening in drain valve
Leave drain plug out UNTIL done winterizing so you can check if any anti-freeze got in water heater due to bad check valve or valving error
THEN put it back in to protect WH Tank threads and keep critters out
