nipple on Dual Flush
Valve as shown in
picture. Make sure both
tubes are clear of ll
valve and ush valve
operation. Ensure hose
clamp is secure.

Slide rubber gasket (P) onto threaded
end of ush valve. Use old gasket if
supplied new gasket does not t.

Secure tank to bowl with bolts (G), rubber
washers (H) brass washers (I) and hex nut (J).
Tank should be level after it has been installed.
NOTE: DO NOT over-tighten. May break tank.
Nut will not be used with all toilets.

Attach handle lever to tank and hand­tighten lever lock-nut.
Note: Nut is reverse threaded. Make sure
tabs on collar are oriented vertically.

Line up tabs on lever into the slots on
lever mounting base (B) and snap into
base. Tabs on lever shank need to be
installed vertically.

(1) Reconnect water supply line (V). Use
Step 3.1 chart (on pg. 13) to determine
the appropriate assembly parts required
to properly reconnect the water supply.
NOTE: Hand tighten only. DO NOT use
thread lubricants. Use of thread sealants
or lubricants can damage plastic nut
and result in ooding and property
damage.

If you need to adjust the
orientation of the ush
valve (A), release from
base by (1) turning
counterclockwise until
tabs unlock. (2) Lift
valve out and
adjust/orient as needed.

Turn on water supply. Check for leaks.

Engage the stop (D) to lock the
position of the blue oat (M).

The grey oat controls the full ush. Pull out stop (D) on grey oat (E).
Activate full ush by pushing lever down. If residual water after ush is lower
than line marked in step 1.1, raise grey oat and repeat. If residual water is
higher than line marked in step 1.1, lower grey oat and repeat.
You may be able to save water by moving grey oat upwards.

Test ush - put toilet paper in
bowl and (1) lift lever to ush
toilet. (2) Pull out stop (D) on
blue oat (M) and lower one
step. (3) Engage the stop (D) to
lock the position of the blue oat
(M). Wait for tank to rell before
retesting.

Lower the setting on blue oat (M) one step at a
time until the paper fully ushes. The higher the
blue oat, the more water you save.

(1) Add a gallon of water to bowl.
(2) Wait 10 minutes, allowing water to settle.
(3) Mark water level with a wax pencil.
(4) Flush toilet.

a. If the water reaches your mark in the bowl and the ll valve is still
running, then decrease the water entering the bowl: See step (5).
b. If the valve shuts o before the water has reached your mark in the

bowl, then increase the water entering the bowl: See step (6).
(5) Push down on the roller (Y) and roll it to the next lower number. Repeat
step (4).
(6) Push down on the roller (Y) and roll it to the next higher number. Repeat
step (4).

Continue adjusting in this manner until the water reaches your mark in the
bowl at the same time the ll valve turns o in the tank.

The rell tube (Z) directs water into the ush valve and down into the bowl
during a ush. If too much water enters the bowl, it is wasted going over the
trap and down the drain. The roller clamp (Y) regulates the amount of water
entering the bowl.

Use chart to determine the appropriate assembly parts required to properly reconnect the water supply.
DO NOT use plumber’s putty to seal these fittings (Teflon tape optional). Do not use thread lubricants. Use of thread sealants or
lubricants can damage plastic nut and result in flooding and property damage.

Use Fluidmaster coupling nut
and cone washer to replace
existing parts. Water supply
tube must extend 1/2 inch
inside threaded shank of valve.

Use existing coupling
nut and existing flat
washer.

Use existing spiral
cone washer.

Captive cone washer
already included.
No additional
washers required.

Do not use Fluidmaster's
coupling nut and the
cone washer on plastic or
metal tubing as shown.

CAUTION: DO NOT use CONE WASHER with PLASTIC SUPPLY LINE or METAL SPIRAL TUBING.
CAUTION: Locknut and coupling nut should be hand tightened only! Over tightening locknut or coupling nut could result in

breakage and flooding.

WATER LEVEL IN BOWL IS TOO LOW

Move roller clamp to higher number.

There may be debris at seal. Sand and rust move through water pipes.
Always clear debris from water lines. See “Flushing Out the Debris” below.
The seal inside the valve top may be damaged-replace with a genuine
Fluidmaster 242 seal.

FULL FLUSH WILL NOT ADEQUATELY REMOVE WASTE

Lower grey oat to allow more water to be ushed.

HALF FLUSH WILL NOT ADEQUATELY REMOVE WASTE

Lower blue oat to allow more water to be ushed.

SEAL LEAKING

Should dual ush valve leak, unclip valve from base, and re-align seal.

FULL FLUSH CLOSES IMMEDIATELY AFTER LEVER IS RELEASED

Top of rell mount should be set 2” above top of overow tube.
Raise rell mount higher. (see step 2.4)

OVERFLOW TUBE STICKS OPEN ON FULL & HALF FLUSH

Remove cable mount from Dual Flush assembly. Check lever cable for kinks.
Straighten by hand. If cable still sticks, replace cable.

Go to our website at www.uidmaster.com for more solutions to toilet problems.

Replace cap assembly.
