I don't worry about the black and grey tanks themselves. But I do worry about the length of pipe between the tank and the gate valve. I waste about $3 (sorry DrewE) and pour a gallon of antifreeze into the tanks (1/3 in grey, 2/3 in black) to make sure that those lengths of pipe do not freeze and crack.
