“3 part series on survival sanitation”
That is just sad. lol.
The very first thing I think of when the possibility of power outages arrives is to fill the bathtubs and use a plastic bag to seal the drain plug so the water doesn't seap out. BTW, it takes less than a gallon of water to flush the toilet by pouring fast into the bowl, then slowly pour another pint into the flushed bowl, to leave water sealign the gass from coming into the house via the toilet pipes. When I've had to do this before, I always leave the tank full and flush via direct pour.
