I hear ya!
I can imagine trying to come up with a “flushing procedure” for the guests.
It’s awkward to say the least.
When there's not enough water the toilet paper catches on part of the septic before it hits the tank. So everytime it clogs we have to dig it up. You just sigh when trying to decide to tell guests to either flush with extra water or tell them "Don't flush the toilet!". LOL
We don't get many guests. ;-)
