: I have four kids and four toilets (and a thirsty dog), and I am looking to upgrade three of them (the toilets, not the family). I bought a Sterling round bowl 1.6 gpf about 3 years ago, that works real nicely. I can't seem to find this anywhere, and decided to start from scratch. Based on this site and reading the surveys from NYC, LA Dept of Water & Power, and other stuff at http://home.earthlink.net/~wliebold I am thinking of trying the Toto Kiki CST-703. Does anybody know whether this is a pressure tank system? have any experience with it? Any suggestions? Thanks

The CST703 is gravity with a standard 2" flushvalve. Performance on this is good, not much bowl water depth though.

Pressure assist start in the $250 plus range.
