Highcool A2422M 3-Inch Dual-Flush Top-Button Toilet Kit for 2-Piece Toilets (48mm Ceramic Lid)

Restore strong flushing performance and stop common tank leaks with this Highcool A2422M 3-inch dual-flush replacement kit. Designed for two-piece toilets only (not compatible with one-piece models), the unit features a top-mounted dual flush button and a 3-inch flush outlet for reliable waste removal. Compatibility note: dual-flush installations typically use a ceramic lid with a 48mm hole. Important: fill valve, bowl gasket, and tank-to-bowl bolts are sold separately. Adjustable fit and water control: the overflow tube extends to fit heights between 11.33" and 15.27". Built-in half- and full-flush adjusters let you manage water use — half flush for everyday waste, full flush for heavier cleaning. Leak prevention: replacing worn flappers, chains, or handles with this dual-flush assembly helps eliminate the typical causes of tank leaks.
