hot water pressure relief leaking antifreeze?
I noticed my camper's hot water pressure relief valve is leaking antifreeze today? is that normal under freezing temperatures? I'm in upstate NY.

I ruined a water heater one year, even though it was "drained."
What happened: I pulled the drain plug, saw water running out and then left to do something else. When I came back, the water no longer was draining so I put the plug back in. I used no antifreeze in the rest of the system. In the spring I found the water heater was cracked.
I had made at least two mistakes: I did not open the hot water faucets in the trailer when I was "draining" the water heater, nor did I open the pressure relief valve on top of the water heater. So, apparently a vacuum was created in the hot water system that prevented full draining of the water heater.
Nowadays, when I drain the water heater I open the water faucets and the pressure relief valve and even leave the drain plug out for the winter. I also now have a bypass to the water heater and use antifreeze in the water pipe system.
Belts, suspenders, underwear...I'm covered one way or the other now.
