Replace the One-Piece Toilet 84995 Flapper

Bold_Look_of_Kohler.jpg

Some Kohler one-piece toilets have had an upgrade to their flappers to help them work longer and more effectively. While this flapper may look different than others you have seen, or even the one your toilet originally came with, this flapper is a direct replacement. Follow the instructions below to change out your flapper.

  1. Turn off the water supply on the wall and flush the toilet to drain the toilet tank water.
  2. Note the location of the S-hook on the current flapper chain and the location of the flapper bar mounting groove on the back of the flush valve (Fig. 1).
  3. Disconnect the S-hook from the trip lever arm and remove the existing flapper. The old flapper can be discarded.
  4. Locate the same groove on the back of the flush valve used by the original flapper. With the prongs on the bar pointed toward the back of the tank, slide the bar into the flush valve from the side. Center the bar on the flush valve and rotate it so the prongs are pointing upward (Fig. 2).
  5. Attach the flapper arms one at a time to the ends of the bar. The flapper should move up and down freely on the flush valve body (Fig. 3).
  6. Reinstall the S-hook to the flapper chain at the same location as the original flapper and attach the S-hook to the trip lever arm. Ensure the flapper chain is taut. 
  7. Turn on the water supply and allow the tank to fill with water. Flush the toilet several times to verify proper operation.
