bypass valves

I have winterized numerous previous RVs but this is the first for my 2016 32rl Sunset. I am used to having either one valve or three which are self-explanatory. But ours has only two, one bypass-blue/red line and one in the blue-cold line behind the water heater. Once I open the bypass and close the blue for winterization what is stopping the antifreeze from going back into the heater through the red-hot outbound line? Is there some kind of backflow valve built in?

I had the exact same confusion last year when I went to winterize for the first time. Could not wrap my head around it till I googled it. Glad its not just me.

In the picture when you turn the bottom valve it stops the water from entering the water heater. The water then goes up the blue/red line to the valve. You then open that valve and the water goes to the "Tee" at the top. The water heater has a "Check Valve" that allows water out but not in. It is located where the red line comes out of the water heater.

So to recap - to winterize the antifreeze comes in the blue/cold line and stops at the valve that is shut in the blue line/water heater input so it goes up the blue/red line thru that valve that is open connecting the red/hot and cold/blue lines. It can not go into the water heater because of the check valve so is goes to the ''hot" side of your faucets.

To "DE winterize" Simply turn the valves the other way and water flows in the blue line to the water heater thru it and out the red line to the faucets.
