The unit has a built in flush system. I have flushed it several times as well as snaked it out. Also poured the sanatizer "blue" stuff that breaks down paper in it. We use Scotts and it says Septic safe. Its like there is something blocking the tube. Our batroom is up stairs so the tube is long and not straight.

Even after a successful snaking and the water goes down, without using it or putting anymore paper in it, I can stand there and hit the lever to flush and it comes right back up the pipe. Now you would think after I have used the snake several times and NOT used the toilet it would be cleared out. But it just fills back up. Very odd.
