@David09 - I’d like to see this wonderful flushometer that the article is talking about. I think it would solve at least some of the embarrassing problems you describe, namely the backwash of waste products back into the toilet bowl.
I really think that most modern households need to get with the times when it comes to toilet bowl technology. I’ve heard that in Japan they have some sophisticated jet stream technologies which, coupled with their high end electronics, give new meaning to the term restroom.
The closest I’ve come to anything sophisticated here in the States is the electronic urinal flush valve I see in some men’s restrooms.
I don’t touch any levers. I just walk away, and then this sensor trips and the toilet is flushed. I think we need more space age science brought to our most basic of amenities, like toilets.
