Flapper-Style Flush Valves for One Piece Toilets
If your toilet has a triangle hole in the tank then you must also order the GP83888 flush valve gasket to be used instead of the red flush valve washer that is included with the 83650 flush valve. The GP83888 flush valve gasket must be installed with the larger flat surface facing toward the tank (opposite of the way the red gasket is shown on the flush valve).

Frequently Asked Questions
Q. "How do I replace the seal for a Kohler canister-style flush valve?"
A. As with any flush valve replacement/repair, you'll need to ensure your tank is emptied of water before beginning. Unhook the trip lever from the chain on the side of the canister, and remove the refill tube from the stop on top of the canister. Grasp the stem inside the canister, then turn the stop counterclockwise to remove it. Lift the canister off of the valve base, remove the old seal and slip on the new seal. Replace the canister on the valve bottom, place the stop back on the stem and turn clockwise to tighten. Remember to clip your trip lever back to the canister and replace the refill tube.
Please note: These instructions are applicable to canister valve #'s 1059288, 1069722, 1083980, 1085760 - and might work with flush valves that have the same style stop. This information is provided for your convenience only and PlumbingSupply.com® assumes no liability regarding your use of these instructions.
Q. "How do I adjust the water level for the 84499 conversion kit?"
A. As with any conversion or "will fit" replacement kit, you might need to make slight adjustments for the unit to function exactly like your original valve did. For the 84499 fill valve, you simply turn the adjustment screw counterclockwise to raise the water lever or clockwise to lower the water level. You may need to flush the toilet and keep turning either way until the water level in the tank matches the line on the flush valve overflow tube. If you're not sure where to find the adjustment screw or water level, view our handy parts diagram.
