IS THERE A LIST OF ITEMS NOT TO BE FLUSHED DOWN THE TOILET TO PREVENT PROBLEMS WITH THE GRINDER PUMP?
That is a very good question, MJ! Not that I am aware of. That being said, I guess it would be more common sense when you think of what would actually fit down the toilet. Obviously anything with an extremely hard construction like steel or cast iron or even hard plastics could pose a problem if they get pulled into the grinding blades. Other than that, I can't think of anything else.
