Question about water heater and winterization

Having read and watched quite a few things about winterization, I think I'm ready to tackle it. There is one issue however that I don't understand having to do with the flow of water. I have a water heater that looks like this:



(pulled from this post: http://ourcampingadventures.com/2016...stone-hideout/)

I see the one valve down at the bottom, which I understand will stop the liquid from entering the "cold" side of the heater. But what I don't understand is: what will stop the water from hitting the top "T" and going "left" and filling the water heater? Is there an internal check-valve that prevents water from going in the hot side? I would have expected a valve in place of the top "T."

Thanks!

Just want to make sure I'm not going to accidentally pump six gallons of antifreeze into my water heater.

There is a “one way” fitting on the water heater tank. It’s the brass piece that the red pex is attached to. Just turn that bottom valve 1/4 turn and your good to go.

Just remember to drain your water heater after you turn the shut-off valve. Easiest way is to take out the plug and then flip the pressure release valve at the outside top of the tank.

Good Luck,

Good Luck,
Thanks! Yes, I had done that earlier. Will make sure to verify it's fully empty.
