I have a 1.6 gallon Kohler Wellworth toilet.....but I tweeked its tank plumbing enough it does a double-flush each time. So I made my environmentally friendly toilet use closer to 3 gallons instead of 1.6. And this Kohler toilet hasn't clogged up in a few years, actually. Its "adjusted" flush is now quite powerful, due to my fucking with it. Yes, I turned a low-flow toilet into a raging water monster. One reason why my toilet never clogs is because I'm obviously too perfect and saint-like to shit! When my shit reaches the end of my intestines, a bunch of angels appear and magically carry my turds up to Heaven in an act I call Immaculate Excretion. Sometimes, when I look up into the sky, I can see my own shit drifting up into the clouds on columns of holy, magical white light.
