If your fresh water tank and waste tanks are all drained except for the gallon you added back, I would purchase 2 gallons of the pink RV antifreeze and add half a gallon each to the black and grey tank and use the other gallon to pour down into the P-traps of your sinks and shower. Easy insurance for about 7.00 at Walmart.
