8. Adjustments
Tank Water Level
Turn the adjustment screw counterclockwise to raise the water
level. Turn the adjustment screw clockwise to lower the water
level.
Flush the toilet and repeat this procedure until the water level in
the tank matches the line on the flush valve overflow tube.
Bowl Water Level
NOTE:
The bowl will fill with water to a full seal height when the
blade of the thumbscrew at the top of the white plastic tube is
pointing at the 1 o’clock position. Only increase bowl water flow
enough to ensure that the bowl refills to the full seal height.
Use the trip chain to lift the flush ball in the tank slightly to allow
water to trickle into the bowl until the water level in the bowl
stops rising. This is the full seal height and should be noted for
subsequent adjustment.
Flush the toilet.
