Sorry, inventors of Brondell Perfect Flush. I think it is a great concept, however, a regular toilet is not designed to flush paper and solid waste with reduced amounts of water, so the likelihood of clogging or having to flush twice after installing dual flush conversion kit or a water displacement device increases. Standard US toilets clear the bowl with siphon technology, so the diameter of the trap way has to be a small as possible (please view siphon vs. washdown technology here http://www.youtube.com/watch?v=_z6pymOet7g&feature=channel_page.) If you are serious about saving water, want a toilet that really works and is affordable, I would highly recommend a Caroma Dual Flush toilet. Caroma toilets offer a patented dual flush technology consisting of a 0.8 Gal flush for liquid waste and a 1.6 Gal flush for solids. Caroma, an Australian company set the standard by giving the world its first successful two button dual flush system in the nineteen eighties and has since perfected the technology. Also, with a full 3.5” trap way, these toilets virtually never clog. All of Caroma’s toilets are on the list of WaterSense labeled HET’s http://www.epa.gov/watersense/pp/find_het.htm and also qualify for several rebate programs currently available throughout the US as well as LEED points. Please go to http://www.caromausa.com for more detailed information or visit http://www.ecotransitions.com/howto.asp to see how we flush a potato with the half flush (0.8 gallons), meant for liquid waste.

Yes, for solids you would need a whole flush - however for the 8 out of 10 trips to the bathroom where you only urinate, you do not have solids to flush and therefore a half flush is just fine. Yes, you might use a small amount of TP when urinating if you are a woman, but that amount should be minimal. I don’t think you need the power of a potato flush to handle that one!
