Hot water drain
I have the hot water plug with a drain cock in it like a car radiator has , if I leave the plug in and just open the drain cock is that good enough for the winter? I prefer not to use the pink stuff ...

Unless you have a by pass installed on your heater you will automatically fill the hot water tank when you pump antifreeze through the rest of your water lines. If you do have a bypass installed then you should always want to drain water from hot water tank before you bypass it. What you're saying does not compute.
I don't use the pink stuff in my water lines at all. I blow them out and leave the faucets open. I use the pink stuff in my sink and tub traps and in my holding tanks. I blow the water heater out also. What I was asking was , if leaving the petcock open was safe or do I need to remove the WHOLE DRAIN PLUG.
