The flush water comes from the top of the bowl. The bottom of the bowl has a small macerator pump and then a duckbill valve that works like a check valve/sewer trap. After the duck valve is the 1 1/2" hose going to the holding tank. The holding tank has a vent. If any of these components are blocked, partially blocked it can cause back splashing.

In addition to Brian’s comments I’d add two things if you have not changed the choker valve (rubber duckbill) in the last few years I’d start with that as it’s probably time anyway. A few years ago we experienced a similar problem n it was the blades on the toilet mascerator, one broke. When it broke the flushing noise changed its pitch as well as experiencing a back flushing. Has your flushing noise changed as well? If so it may well be the under toilet mascerator(that’s where ours was mounted). Keep us posted as to the outcome.
