Water Level Adjustment
Depending on the manufacturing plant, you may have one of two of the following fill
valves:
Type A Type B
Water Level
For Type A Fill Valve:
Refer to the water level (WL) setting marked
on the inner wall of the tank. Allow the wa-
ter to fill the tank. Turn the adjustment screw
clockwise in the (+) direction to increase the
water level height (see Illustration 1). Turn
the adjustment screw counter-clockwise in
the (-) direction to decrease the water level
height. Flush the toilet to verify the correct
water level. Adjust as necessary.
For Type B Fill Valve:
There are no water level adjustments. The
fill valve has been preset at the factory.

Replacement Procedure (continued)
7) Connect water supply to fill valve shank and hand-tighten only.
NO TE: Do not overtighten. These are plastic parts. Never use pipe dope on any
water supply connection.
8) Attach refill tube to fill valve nipple and clip other end of refill tube to the overflow
pipe.
9) Turn water supply ON and check for leaks outside the tank.
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.
WARNING!
DO NOT USE IN-TANK BOWLCLEANERS.
The use of high concentration of chlorine or chlorine-related products can seriously
damage fittings in the tank. This damage can cause leakage and property damage.
