Gerber avalanche 1.6 gallon
I had three installed at the same time by two different plumbers, one plumber was more knowledgable than the other. Hence one Gerber toilet had to be replaced due to clogging. Once changed all three have never clogged. I have had them for almost two years with three kids. I even added a half gallon plastic bottle to the tank to reduce water usage and still works exceptionally. This has reduced my water usage from 1.6 to 1.1 gallons a flush. If installed correctly this is the best money can buy.
