Buy a couple gallons of RV antifreeze (Not car antifreeze) to keep on hand... In a pinch if you are somewhere and it starts to freeze dump a gallon in your toilet and the other gallon in all the other drains (to fill the P traps and the grey tank)... This is only if you are pinch to keep the black & grey from freezing for a short time
