With a tall, narrow tank, the Viper toilet is designed to optimize flush speed for optimal waste removal. The Viper comes equipped with the Fluidmaster 400A fill valve for quick tank fill. Powerful front rim jets maintain a clean and sanitary bowl with every flush, while a fully-glazed, 2” trapway offers clog-free operation. An exclusive multipoint mounting system ensures long-lasting stability. Extra-tall bolt caps eliminate the need for bolt trimming.
