Composting Toilets and Diarrhea

The Green Apple Splatters, The Hershey Squirts, Bubble Guts, Code Brown, The Runs, Montezuma's Revenge, Mudd Butt, Organic Brown Lava, The Trots and my personal favourite – The Arsequake. No matter what you call it, we’ve all had it at one time or another and we’ve all had to deal with the after-effects (which are never pretty).

Now if you have a flush toilet in your home, you press the button and all evidence of your regrettable 3 am lamb kebab or dodgy-looking food wagon seafood pie is flushed away. With a composting toilet, you have to deal with things a little differently and we’re here to let you know how.

What to do if you have diarrhea on a composting toilet

Now you’re probably thinking to yourself (other than “I’m never eating three-day-old steak again”) “Can my composting toilet handle diarrhea?” Well, the answer to that question is yes – a composting toilet can certainly handle diarrhea.

Because Diarrhea typically has a little more liquid in it than normal ‘poop’ you may find you might need to run the exhaust fan a little more than you would normally to help evaporate the additional liquid.

Other than that, your composting toilet should function as normal, without any issues.

How to clean a composting toilet if you diarrhea

This is a pretty straight forward process and you may want to go check out our article How to clean a composting toilet for more info but the process is very easy. Simply swish some of our Nature Flush Enzymes around the bowel and scrub with a toilet brush. You may wish to spray some water around the bowl or pedestal afterwards or simply wet some paper towel and wipe down.

As you can see having a composting toilet at home when one or multiple family members have diarrhea is not really an issue, you just need to approach cleaning the after-effects slightly differently than with a flush toilet.
