Does not have the power to move a turd of substantial size...
15,000 gallons saved per year? I find that hard to believe. That's about 40 gallons of water per day saved, or 10 gallons per person. Considering that toilets in the US only use about 1.5 gallons per flush, and assuming that the dual-flush thing saves one gallon per flush, that each family member would would have to use *that* particular toilet over ten times per day to hit 15k gallons saved.
I'm not sure what kind of diet the people at HydroRight are on, but I think I'll stay away from their offices...
1.5 gallons per flush is the newest low flow toilets. A lot of homes have toilets that use more like 5 gallons per flush. This is the toilet that they are expecting you to use this in. That is 2 or 3 flushes a day, easily achieved by the average person.
If you really want to save water pee in the sink like Adam Carolla or better yet off a balcony/deck.
