Has anyone had any experience with a Zoller Qwik Jon Model 203 and what toilet did you use for this. I can't get the manufacture to give me a make or model that will fit this rear outlet application.
The only 2 I can find off the top of my head are American Standard Yorkville and Kohler Barrington. Both of those are pressure assist, which seems pointless with a pump system, but your choices are quite limited.
