I don't know what brand you use, or where you live or what your low temperatures are. but what I said about that particular brand that it's rated for minus 50 and the temps have been nowhere near that cold and the stuff is frozen solid, the whole jug. I am only trying to warn people about that brand. Use it at your own risk.we use an rv and marine and we've owned several campers and haven't noticed any issues in plumbing
I have seen it freeze but just be slushy not hard froze[/QUOT
