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.
N OTE: 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.
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.
