Gerber Plumbing Fixtures is thrilled to announce new design and function enhancements to the Viper toilet line. Building on the style and efficiency of the existing line, the new Viper features distinctive beveled tank sides that flare out at the top for a leaner, more tapered aesthetic. This tall, narrow tank optimizes flush speed and quickly refills with an industry-best Fluidmaster 400A fill valve. Additionally, the tank cover’s tight fit offers a sleeker appearance. Inside the tank, an upgraded 3” rigid flapper ensures reliable, lasting performance that professional installers rely on, and users have come to expect. A larger footprint also makes the new Viper ideal for replacement applications.
