This Wellworth dual-flush toilet tank combines water savings with powerful flush performance. An innovative two-tone flush lever offers the choice of 1.1 or 1.6 gallons per flush; the dual-flush lever is located on the side of the tank like a traditional toilet, leaving the top free for storage. The high-efficiency 1.1-gallon flush reduces water use by more than 30 percent over the 1.6-gallon mode, which adds up to potential water savings of more than 4,000 gallons per toilet, per year.


  • Left-hand nested trip lever offers a choice of 1.1 or 1.6 gallons per flush (gpf).
  • Combines with the K-4197 or K-4198 bowl to create a complete K-3987 or K-3988 Wellworth toilet.
  • Combines with the K-4199 bowl to create a complete K-3989 Highline toilet.
  • Coordinates with other products in the Wellworth collection.
