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 and C Fill Valve:
Refer to the water level (WL) setting marked
on the inner wall of the tank. Allow the wa-
ter to ll 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.

7) Connect water supply to ll 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 rell tube to ll valve nipple and clip other end of rell tube to the overow
pipe.
9) Turn water supply ON and check for leaks outside the tank.
NO TE: As water lls the tank, water is also directed into the overow tube via the
rell tube. This additional ow of water is critical to relling your toilet’s bowl.
Once the water stops filling the tank, some residual drops of water may drip
from the ll valve. This is NORMAL as these drops will subside.
MAINTENANCE INSTRUCTIONS

2) Flush toilet and remove remaining water from tank with a sponge.
3) Remove the water supply connection at the ll valve.
4) Remove old ll valve and use damp sponge to clean hole in tank.
5) Place new ll valve inside tank hole.
6) Thread mounting nut onto ll valve shank and tighten the nut.
NO TE: Do not over-tighten. Be sure to install fill valve in a position that does not
