The heart of the 6616 toilet lies in its advanced flushing system. Featuring a dual-flush mechanism, users can choose between a solids discharge volume of 1.6 gpf and a water-saving liquids discharge volume of 1.1 gpf. This not only ensures robust drainage capacity, but also allows customers to select the discharge volume based on their needs, thereby conserving water and protecting the environment.

In addition, its smooth, non-porous porcelain surface effectively resists stains, odors, and bacteria, simplifying cleaning and maintaining a pristine bathroom environment. A quick-release seat further enhances hygiene, allowing for easy removal and thorough cleaning.
