So I use to own a house with a below grade toilet that used an upflush. Anyway one day it stopped and was just making a stuck motor noise so I turned off the breaker and decided to deal with it later. I tell my wife that the power is off to the downstairs bathroom and to not use it no matter what.Looks like this may be a new style toilet that fillets a turd to prevent stoppages?
I don’t know, but you asked!
The next day I hear her yell..."The downstairs toilet is Overflowing."
Anyway I had to shop vac it out and carry it outside to the toilet upstairs (house was built into a slope) . Then same process with the up flush tank taking several trips #thisiswhyiownagasmask. Inside the up flush tank was perhaps the scariest device I have ever seen. An array of turd cutting blades that spin producing a hyper stream of pressurised turds that then shoot up the pipe. It had been blocked by a piece of bone?! Even with the power off removing it just had this sense of dread of getting my fingers chopped off by turd blades while a stream of poop sprays in my.face. but in the end... Mission accomplished
