Abstract: A water-saving flush valve control mechanism is formed as a single unit that can easily be retrofitted onto existing toilet architectures with only one fixed attachment point. Water usage is reduced by providing the user full control in opening and closing the buoyant water valve. Control is achieved by a vertical rigid spine that is attached between the toilet handle arm and the valve. An adjustable lateral extension is included and placed between the toilet handle arm and the vertical rigid spine to ensure that the spine is properly positioned over the valve. Pivotable attachment of the spine to the lateral extension accommodates the arcing pathway of the buoyant valve. A float arm may be added and used to counterbalance the additional weight associated with the flush valve control mechanism.
