F
lush Cartridge
A. Turn off water supply and flush toilet.
B. Pour water onto top of cartridge (Fig. 1) and turn on water.
C. Watch for air bubbles. Consistent flow of bubbles indicates cartridge needs to be
replaced. No bubbles visible, move on to Step 4.
Step 2.
F
lush Cartridge Replace
m
ent
A. Turn off water and flush the toilet.
B. Use the handle end of pliers (Fig. 2) to unscrew the cartridge from the vessel.
C. Drop in new cartridge and screw in until one female thread (Fig. 3) of vessel
is showing.
D. Turn on water. Continue to screw in cartridge slowly, 1/8 to 1/4 turn increments
until water stops running into the bowl and tank pressurizes.
Step 3.
A
ctuator
A
djust
m
ent
A. Start by loosening the setscrew in the center of the actuator. Adjust the height of
the actuator by screwing it up or down. There should be a gap (Fig. 4) (about the
thickness of a penny) between the rod and actuator when gently lifting the rod.
When accomplished tighten the setscrew in the center of the actuator.
Step 4. Check
A
ir Inducer
A. Place several drops of water over hole on top of air inducer and flush toilet (Fig. 5).
If drop is vacuumed in, move onto step 6. If not, air inducer needs to be cleaned.
Step 5. Clean
A
ir Inducer
A. Turn off water and flush toilet. Unscrew the cap of the air inducer (the smaller of
the two caps) (Fig. 6).
B. Pull the duckbill out from the cap and clean it by gently squeezing it (Fig. 7)
between your fingers under a flow of water. Inspect the lips of the duckbill.
If they are deformed, the duckbill needs to be replaced.
C. Reassemble, insert the duct bill into the housing (Fig. 8) body and reinstall the cap
to hand tight.
Step 6. Clean Inlet Screen
A. Clean the inlet screen by turning off the water supply, disconnecting the water
supply line from the supply shank and removing the screen with a paper
clip (Fig. 9).
B. Clean screen (Fig. 10) and replace.

1. Pressure-assist toilets get their energy from the water supply.
2. All pressure-assist toilets get their energy from the water supply line. It is important
to have sufficient pressure at the supply. The minimum line pressure for a 1.6 gpf
system is 20 psi and 25 psi for 1.0 gpf.
3. A blocked bowl or drain will affect the fixture’s performance. To check for this, pour
2 to 3 gallons of water into the bowl. If the bowl accumulates water in it, this would
indicate that something is blocking the bowl/drain. If you need additional help,
please contact the manufacturer of the flushing system, or do a word search on
“pressure-assist toilets” on the web.
