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 have to agree with Terryallen. The water heater wasn't drained, as that's the only way water/antifreeze could be leaking out of the relief valve, which is high up on the tank. Antifreeze also got into the water heater, which makes it appear that the heater wasn't bypassed. The cold water lines are probably OK, as they were purged with full strength antifreeze. The water heater and hot water piping only have dilute antifreeze in them making them subject to freeze damage.
My suggestion to stop further damage is to turn the heat on in the TT and remove the drain plug in the water heater. Removing the plug so it drains melt water outside will at least reduce the amount of water that leaks into the TT if the tank has split. The ice in the heater is going to thaw anyway when the weather gets warm enough and you want to minimize interior water damage. The hot water lines don't hold a lot of water, so leaks from cracked fittings shouldn't be a big deal. You can pull out drawers and open cabinets and inspection panels to check for pink leakage around fittings.
Good Luck!
