I bought this a Wal-Mart. Blew out my lines a month ago and added the anit-freeze into the lines.

 

Packing up for the trip south. The anti-freeze half-empty was left outside next to the trailer. It has been below freezing pretty much for the entire month. However, it has NOT been below zero.

 

I picked it up to put into the garage and it was slushy, almost frozen solid. We shall see in a couple of days whether I have lost any water lines.

 

I suspect it would be a rock frozen at -50F.

Actually, what you experienced is quite normal. Most antifreeze does turn slushy but does not freeze solid and it does not expand to break fittings or burst lines.

Yep, that's typical of propylene glycol based RV antifreeze. It's the lack of expansion that's the key to its effectiveness.

Expansion or lack of is the correct answer.
