Draining Hot Water Tank

[Cahriad]

When I drain my tank should I put the anode back or leave it out so the tank can get air.? I would leave the pressure relief open also.

I would replace the anode rod so no critters crawl in. We drain ours once a year when winterizing.

Myself when I drain the water heater (like when winterizing) I replace the anode with a piece of screen. I do not leave the pressure valve open because I don't want the spring to loose strength from being compressed all winter.
