Abstract
The disclosure is directed to a flapper system and a flapper system kit that is compatible with both 2″ and 3″ flush valve seats. In some embodiments, the flapper system is configured to enable a user to select either a 2″ or 3″ flush valve seal for the flapper system. In some embodiments, the flapper system includes a pivot that enables sealing of a flat flush valve seat or an angled flush valve seat. In some embodiments, the flapper system includes one or more adjustable window assemblies that control a fluid flowrate within an internal portion of the flapper system to control buoyancy. In some embodiments, the flapper system includes an adaptor that converts a 2″ valve into a 3″ valve.
