- flush pipes that are a little bit wider than standard and thus are almost wide-enough to function properly
- flush pipes that are porcelain coated, and thus slick instead of ultra-rough
- venturi-effect charged-air-reservoir powerflush with powerblaster nozzle directed at the flush pipe -- sounds like a 12-gauge shotgun blast -- you can really feel it hit you in your gut when you flush it
Like I was saying above, I think I would rather just freeze-dry, crush and save-for-once-in-a-long-while-disposal my contributions. Plumbing is so last-century.
