Q. "I have a ballcock style fill valve with a float ball and rod. Will this kit still work for me?"
A. Because of the way the dual flush valve fits over your existing flush valve, there isn't room in the tank for both the dual flush valve and a ballcock style fill valve. We recommend purchasing the complete kit with fill valve and replacing your fill valve with the PerforMAX at the same time you install the Duo Flush valve.
Q. "I installed my new dual flush valve according to the directions, but I still have parts left over..."
A. Depending on what style flush valve you currently have and whether or not you're using the PerforMAX fill valve, you will have parts left over. Both kits include an angled seat adapter for angled flush valves, a brass seat adapter for brass flush valves, an overflow tube and an overflow clip. If you have a straight flush valve and don't use the PerforMAX fill valve, all four of these parts will be left over - which is perfectly normal.
