Abstract
An adapter for attachment to an existing single flush valve system to convert the single valve system to a dual flush valve system comprises a pair of tubular sections vertically offset from one another and connected by a hollow, enclosed channel. The upper section is adapted to engage a discharge pipe of an existing single flush valve system in order to select a discharge level for a lower volume flush and direct water flowing through the discharge pipe through the adapter. The bottom section of the adapter includes a pivotable flapper valve that can be operated independently of the flapper valve disposed on the single flush system in order to provide a greater volume of water for flushing of the toilet. A mounting arrangement is also provided for attachment to the toilet tank which enables the existing and additional flapper valves to be selectively activated using a pair of handles connected to the arrangement.
