Gerber’s Avalanche Elite features a modernized contemporary design with a simple semi-concealed trapway. The trapway makes the toilet easier and quicker to install than many competitive skirted toilets, much like a standard two-piece toilet, Gerber points out. For installation, there is no special hardware or bolt alignment required, no interference with the water supply/angle stop and the seat can easily be installed before or after the bowl is installed. The flushing system has 50% more line carry than the national standard, ensuring no hidden clogs under the toilet or in the pipes. Comes with a Fluidmaster 400A fill valve for durable long-lasting anti-siphon operation and easy replacement.
