Refer to the following directions for adjusting the chain on the GP85160 flapper.
- Turn off the water supply to your toilet and flush the toilet one time.
- Using a pencil, mark the location of the waterline inside of the tank.
- Remove your existing flapper from your toilet tank by disconnecting the hook from the trip lever arm and removing the arms of the flapper from the flush valve.
- Unhook the chain at the flapper end by using a needle nose pliers to pry open the clip holding the chain to the flapper (Fig. 1).
- Compare the old flapper chain to the new chain and cut the new chain to match the length of the old chain using a cutting pliers (Fig. 2).
- From the bit of chain that was cut, remove the connector by slightly separating it and sliding the ball of the chain through the end of the connector. Reattach the connector to the longer chain with the float attached (Fig. 3)
- Adjust the float to the location that it was at on the previous flapper by removing the black disks on both sides of the float with a needles nose pliers (Fig. 4). It is easiest to lift one side of the disk up and pull out to remove them.
- Reattach the black disks on both sides of the float to secure it in place.
- Reinstall the newly sized chain to the flapper by attaching the clip through the ball chain connector (Fig. 5). Then hook the clip back on to the top of the flapper and pinch the clip together with a needle nose pliers (Fig. 6).
- Connect the chain back onto the trip lever arm. Connect the arms of the flapper to the flush valve.
- Turn on the water supply to the toilet and allow the tank to fill. Once the tank has filled completely, turn off the water. Flush the toilet once and confirm that the waterline is at the pencil mark.
Additional Float Adjustments
If the waterline is not close to the pencil mark from step 11, the float may need to be adjusted further.
Lower the Tank Water level
- Raise the float on the chain to lower the water level in the tank.
- This will cause the flapper to close more quickly as water leaves the tank and will result in a lower water level.
Raise the Tank Water Level
- Lower the float on the chain to raise the water level in the tank
- This will cause the flapper to close slower as the water leaves the tank and will result in a higher water level.
