Does anyone have a technical discussion about the differences between these two items. How would your rate each against each other and which would you get. I read some info. on the web but could not seperate the two? I just installed a Supreme (with pwr gravity) and the bowl above the water does not clean well because the water just dribbles down the sides of the bowl, rather than swirl around like the old one. Of course, the 1.6gal is so much less water that you pay the price of not getting the bowl a little cleaner.
Also computed the volume of water that is flushed. The tank filled to the water line measured 377 cu in (1cu in = .004329gal) = 1.63gal of water in the tank (not accounting for valves+flapper). After a flush, the height of the water dropped 2.5in which computes to only 0.82gal being emptied from the tank into the bowl. Now I know that water is still entering through the tube into the bowl while the tank fills up. So the question is, how is the 1.6g/flush computed. Does it mean 1.6g actually goes down the drain?
