IMPORTANT: A flapper with a plastic or metal chain is
recommended for the Leak Sentry
®
to maintain its settings.
Flappers with nylon or vinyl straps will stretch and cause
Leak Sentry
®
to work improperly.
(Replace with a flapper like the Fluidmaster 501 or 502.)
Flush out tank and sponge
dry. Remove water supply
coupling nut and locknut
from under tank.
Remove fill valve from tank.

Use of such products will:
(1) RESULT IN DAMAGE
to tank
components and
MAY CAUSE FLOODING
and
PROPERTY DAMAGE
and
(2) VOID
FLUIDMASTER WARRANTY. DO NOT
overtighten nuts or tank/bowl may crack.

because
it will not damage the components.
400LS WATER-SAVING FEATURES
Prevents wasteful refills in leaky tanks.
The Leak Sentry
®
device alerts you to a tank leak, typically caused by a faulty flapper.
If there is a tank leak, the float cup will not drop to refill the tank until the tank lever is
pushed. On the first flush attempt, the valve will simply refill the empty tank; only then
will you receive a complete flush. This will continue to occur until the tank leak is fixed.
The Adjustable Refill allows you to adjust the amount of water going into the bowl,
eliminating water waste due to the bowl being overfilled.
WARNING
Because drop-in cleaners used in the tank can result in damaged
tank parts (see WARNING above), Fluidmaster recommends the
use of Flush ’n Sparkle
®
Toilet Bowl Cleaning System (Models
8100, 8200 or 8300). It cleans the bowl without harming tank
parts by isolating the cleaner from the tank water, releasing it
only to the bowl where it is needed. Cartridges supply more than
1,000 flushes and are a snap to replace.

Check bowl water level by flushing toilet. If bowl appears to be full but continues to
fill, the valve may be overfilling the bowl causing excess water to siphon down the
trapway. Adjust amount of water going down into the bowl as follows: Fill the bowl
with a gallon of water. Wait 3 minutes until the bowl water level recedes down and
stops. With a pencil, draw a line at the top of the water level in bowl. Now flush the
toilet. If the valve is still filling and the water is up to the line in the bowl, then the
amount of water going into the bowl is too high and needs to be adjusted. Adjust
the refill by turning the roller clamp with thumb to the next lower number. Flush
the toilet; adjust until water level in bowl is at the pencil mark when the fill valve
shuts off. If valve shuts off and bowl is not full, adjust by turning the roller clamp
to a higher number. Repeat until water in bowl is up to line. “O” on roller clamp
equals no refill to bowl.
Flushing Out the Debris: Hold
a cup over the uncapped valve
to prevent splashing. Turn water
supply full on and off a few
times. Leave water supply off.
Check for leaks. Tighten nuts
just enough to stop leaking.
Place cap assembly on top of
gray valve body by aligning
cap arm and adjustment rod
next to refill hose.
Press down on top cap rotat-
ing top & arm clockwise to
locked position.
Turn on water supply.
IMPORTANT: Submerge the
float cup under the water for
30 seconds.
Adjust water level
by turning water level
adjustment screw. To raise–
turn clockwise; to lower –
counterclockwise.
For your convenience, the roller clamp
and hose clamps are pre-assembled to the
refill hose. Attach one end of hose to refill
clip and slide clip to right side of overflow
pipe. Attach other end of hose to nipple on
fill valve with a slight arching (see picture
to the left). Cut tube if necessary. Squeeze
tabs of hose clamp and move clamp to
end of hose, over the fill valve nipple, then
release tabs. Do not shove refill tube down
overflow pipe. This will cause water loss.
FLAPPER CHAIN HOOK-UP
Lift tank lever all the way up inside tank.
Hold tank lever there. Pull flapper chain
tight so the flapper is lifted as high as it
can go and attach chain to hole in lever
directly above flapper. Make sure flapper
chain is straight.
Make sure flapper is closed on seat. If
not, you may need to lengthen the flapper
chain by a link or two to allow flapper to
close and seal tank.

• If float cup does not drop when flushing
the tank: Tighten Leak Sentry
®
chain
by one link and then try flushing again.
Tighten by one link at a time until valve
turns on at flush. See “Hooking Up the
Leak Sentry
®
Chain”.
WATER LEVEL IN BOWL IS TOO LOW.
• Move roller clamp to higher number.
LEAK SENTRY
®
WILL NOT LOCK FLOAT CUP.
• Make sure valve is set at 5 o’clock in tank.
• Make sure water drops below float cup
during flush. Raise the valve higher in
tank and reset water level.
• Device chain should be loose except
when lever is pushed to flush tank. See
“Hooking Up the Leak Sentry
®
Chain”.
• Untangle Leak Sentry
®
chain from screw
adjustment or device area.
CAUTION:
Do not shove refill tube down overflow pipe.
This will cause loss of water from tank.

the Valve Cap
Assembly

Place shank
washer onto
threaded
shank of fill
valve.
Flat
side up.
Then
place fill valve
in tank.
Place valve in tank; do
not install. The Critical
Level mark – identified
on valve – should be
1 inch above the top of
the overflow pipe. This
is a plumbing code.
Remove fill valve from
tank to adjust height.
Adjust height of fill valve
by turning lower shank
in or out of the valve
body.
Do not move lock
ring
. It holds the valve
body and shank together
under pressure. Do not
interchange body with
old shank, as leaking
can occur.
Before installing the
valve, remove the valve
cap assembly. Push float
up with right hand (see
picture). Twist cap and
lever counterclockwise
1/8
th
of a turn to unlock.
Let cap assembly hang
on float cup.
SHANK
WASHER
THREADED
SHANK
Simulate a leak by
slightly lifting flapper
chain to allow 3 or 4
inches of water to slowly
drain from tank.
Fill
valve should not turn
on
, but remain locked
and stay off.
If test fails go to
Troubleshooting
section.
Make sure chain is free,
not tangled or caught.
LEAK SENTRY
®
CHAIN HOOK-UP
Lift tank lever all the way up inside tank and
hold it there. Pull Leak Sentry
®
chain until it
lifts the float cup all the way up the fill valve
shaft. Then connect chain & clip with no
slack in chain to the tank lever.
NOTE: Do not cross Leak Sentry
®
chain and
flapper chain. If lever has only one hole, then
attach to same hole.
If using the
Flush ’n Sparkle
®
cleaning system
the tank should
look like this
when setup
is complete.
