Winter Toilet Use

AMC4

Hello All,
I have a TAB 320 and I would like to use the toilet in the winter. How much anti freeze should I pour into the black tank to begin with and how much should I us for each flush?

I would pour a gallon of the pink RV antifreeze into the tank and you could use another gallon to flush with as needed.  I’d also use either some liquid toilet treatment to eliminate odor or a similar powder based toilet chemical treatment for odor/decomposition purposes. 👍🏻

Most of us go for a 50/50 ratio in the tank with each flush.

Thank You!

Also if the trailer is heated, leave the washroom door open enough to get warm air inside, this will help keep the black tank from freezing, since it is under the toilet above the floor, not under the trailer.
