Septic safe or not.....
If it does not break down in the jar test, don't even put it aboard.
Background Story:
My daughter put a wipe in the pot. First it jammed the valve in the pot, but somehow she got it loose and never said anything.
Then when dumping, the flow would not start. I got it started and I still didn't know about the wipe. At the next dump, the pipe was full because the slide valve was leaking for three days.
When I got the chance to back-flush the valve, the wipe (now a week or more old) still had enough strength to plug up the back-flush set.
I got the wipe free and now everything was working as it should. I showed the wipe to DW. She told me DD have brought those along and though she knew that they should not go into the pot.......
