You did not mention what automatic toilet you have. I personally had the Thetford Aria Deluxe II push button commode. It was large, heavy, and wasted a lot of water. The original owner told me he replaced it twice. In speaking to others, they said it is just a matter of time before it fails and is a very costly replacement. I chose to convert back to a manual model. That way I could do it on my timetable instead of an emergency situation.
