NO TE: As water fills the tank, water is also directed into the overflow tube via the refill
tube. This additional flow of water is critical to refilling your toilet's bowl. Once the
water stops filling the tank, some residual drops of water may drip from the fill
valve. This is NORMAL as these drops will subside.
Refer to the water level line stamp inside the tank.

end of the fill valve. Use a flathead screwdriver to
make adjustments:

• To lower the water level: turn the screwdriver
counter-clockwise, or towards the '-' indicator.
