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.
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 Type C Fill Valve:
Refer to the water level (WL) setting marked
on the inner wall of the tank. Allow the water
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.
