TOILET TANK FILL VALVE INSTRUCTIONS

1) Shut off the water supply to the toilet.
2) Flush toilet and remove remaining water from tank with a sponge.
3) Remove the water supply connection at the fill valve.
4) Remove old fill valve and use damp sponge to clean hole in tank.
5) Place new fill valve inside tank hole.
6) Thread mounting nut onto fill valve shank and tighten the nut.
NO TE: Do not over-tighten. Be sure to install fill valve in a position that does not
interfere with the trip lever operation.
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.
Depending on the manufacturing plant, you may have one of two of the following fill
valves:
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 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.
