Unfortunately the first video of this was lost with my old phone so this is all I have of it before restoration. I am fairly disappointed with this because the elongated ones are such good performers.
I have a 2023 one in my house. It has trouble sometimes but I think is a problem with my house because I’ve had 3 different toilets in the same bathroom and they all acted strange
I think this is the way most water saver toilets work… for Number 1, use the quick flush-and-release to use the least amount of water needed to clear the bowl… for Number 2, you gotta hold the handle down until the tank is empty, uses more water but it gets the job done.
I 100% second that. My parents house has 2 original Champions from 2005 (which have had their flush valves replaced with the Champ 4 flush valve which is IMO superior) and a 2013 Champion 4. I have a 2020 Champion 4 Max in my house and there is no comparison. I haven't clogged it or anything, but the flush is just far inferior.
