We Need a Toilet!
After a big quake, you won’t be able to flush your toilet, since the water is off and there are who-knows how many breaks in the main sewer lines. Pouring water in the toilet to flush it will have to stop if it backs up.
There are outside solutions, of course – like digging a “camp” latrine. But here’s a possible way to keep using your bathroom:
Go to Home Depot or any big hardware store and buy a box of what they call “construction bags.” They are sort of like a regular leaf bag on steroids: they are very thick.
After the quake, turn off the water at the wall stop, flush the toilet with the water that is left in the tank, lift the toilet seat, take one of the bags and wrap it around the toilet opening. Put the seat back down and you have your “portable” toilet.
Minimize difficulties by having the men (especially) go outside to urinate.
