Turn off the water supply for the toilet where you will be replacing the flush kit. The water supply valve can be found by following the tube or hose at the bottom of the tank to where it meets the supply valve at the wall. Rotate the knob on the end of the valve clockwise to turn off the water.
Remove the toilet lid. Press the handle to flush the toilet. Continue pressing down on the handle until all the water inside the tank empties. Wipe up any remaining water with the sponge and towel.
Disconnect the flapper chain from the flush handle. Examine the end of the flush handle rod where the flapper chain connects. Remove the chain by either unhooking the end of the chain, or use the needle-nose pliers to open the loop connecting the chain to the handle and pulling it off.
Remove the toilet flapper. There are a number of ways this can be done, depending on your flapper model. The easiest method is to unsnap the flapper from the hinge holding it in place at the bottom of the tank. Other flapper models may either slide off over the overflow tube or be inserted into the outlet on the bottom of the tank.
Replace the old flapper with a similar model. Follow the manufacturer's instructions for installation.
Connect the flapper chain to the flush handle rod.
Restore the water supply by turning the shut-off valve counterclockwise. Allow the tank time to fill. Flush the toilet and check for proper flush operation. Replace the tank lid.
Things You Will Need
- Toilet flush kit

- Silicone grease (optional)
