The Quiet-Flush toilet provides both quiet operation and
user control of water levels in the toilet bowl. A single
large push button switch provides a simple flush mode
by activating both the rinse water supply and the macerator discharge pump
switch offers independent control of the rinse water supply
and discharge pump separately so the bowl water level
can be easily raised or lowered by the user. This provides
a method of minimizing water use, when desired, as well
as a means of raising the water level in the bowl when
appropriate for user comfort. It also allows for complete
evacuation of the bowl water while underway in rough
sea conditions.

INSTALLATION
PLUMBING
The toilet can be plumbed to any pressurized water system that can provide a minimum of 3-1/2 GPM (13.5
LPM). This may be a fresh water system including the
vessel’s potable water system or a washdown system
utilizing either fresh or salt water. However, it must be
connected to a pressurized system that normally remains on at all times while the vessel is in use.
To make the water connection, shut off the water system
pump and open one of the systems faucets or fixtures to
drain the pressure from the system. Select an appropriate tee type fitting that can be installed in the existing
pressurized water system and will provide a 1/2"
(13mm) hose barb to feed water to the toilet. Install the
tee fitting at a location on the pressurized water system
that provides convenient connection to the toilet’s
solenoid valve/ siphon breaker assem
being connected to the vessel’s fresh water system and
the vessel may be connected to an unregulated city
water supply, it is recommended that a valve be installed
in the toilet water supply line ahead of the solenoid
valve/siphon breaker to regulate the flow rate of
incoming pressurized city water.

INSTALLATION (continued)
PLUMBING
The solenoid valve/siphon breaker should be positioned
a minimum of six inches above the hose connection at
the back of the toilet bowl (at all angles of heel and trim)
and located as close to the toilet as possible. It should be
located where an occasional drop or two of water from
the siphon breaker will not adversely affect nearby equipment or supplies. It must be installed in a vertical position
with the hose barb connections pointing down. The solenoid valve/siphon breaker bracket should be secured to
a solid mounting surface with four screws. If the valve
assembly is attached to a wood surface, 3/8" (10mm)
long screws are generally adequate to support the
weight of the valve assembly. If desired, the valve
assembly may be installed inside a cabinet or locker to
conceal it from view of the vessel’s occupants. To provide
a clean sanitary appearance inside the head area, a
foot section of smooth white hose is provided with the toilet to connect the toilet bowl spud fitting to the siphon
breaker outlet hose barb.
The solenoid valve inlet hose barb is then connected
with 1/2" (13mm) reinforced vinyl hose suitable for
pressurized water to the tee fitting installed in the water
system line. All pressurized water system connections
should be secured with stainless steel band type hose
clamps. The 3/4" hose connecting the siphon breaker to
the bowl should be secured with a band clamp at the
siphon breaker to prevent it from being accidentally
dislodged but generally does not need a hose clamp to
secure it to the bowl spud fitting unless desired for added
security.

to 1-1/2" (38mm) hose, if desired. The discharge plumbing should be kept as short as possible and bends in the
discharge hose should be kept to a minimum.
If the toilet is below the water line and is plumbed to an
overboard discharge through hull, the discharge
plumbing must include a vented loop positioned so it
remains above the water line at all angles of heel and
trim. Total discharge head should not exceed 4 feet
(1.2m). To retain water in the bowl, the discharge hose
should be looped upward about eight to ten inches
above the base of the toilet and as near to the toilet as
can be practically accomplished without creating an
unsightly plumbing situation.
The discharge port includes a 1" (25mm) hose barb and
should be plumbed with 1" (25mm) hose to an on board
holding tank or, if appropriate, to an overboard discharge
through hull. A 1" (25mm) to 1-1/2" (38mm) barbed hose
adapter is provided to adapt a 1" (25mm) discharge hose

ELECTRICAL
The electrical wiring should be independent of all other
accessories. It should be made with marine grade
copper stranded wire of the gauge specified in the
electrical specifications chart. Make all wire connections
with mechanical locking type connectors (crimp type butt
connectors and terminals). Ensure the circuit is protected by a proper sized fuse or circuit breaker determined
from the electrical specifications chart. Secure all wires
to a solid surface approximately every eighteen inches
(1/2m) along their entire length of run.
Wire the switch panel to the solenoid valve/siphon breaker and toilet pump assembly as per the following wiring
diagram. Select a location for the switch panel that is
convenient to the toilet user and will also allow access to
run the wires from the switch panel to both the toilet’s
motor and the solenoid valve/siphon breaker as well as
from the electrical power source to the switch panel. The
red lead from the panel should be connected to an overcurrent protected positive power source. Connect the
brown lead from the panel to the waste pump positive
(orange) motor lead. Connect the black waste pump
motor lead to battery negative. Connect the yellow lead
from the panel to a solenoid valve terminal. Connect the
remaining solenoid valve terminal to battery negative.
The solenoid valve is not polarity sensitive.
To install the switch panel, drill two 1-3/4" (45mm)
diameter holes (slightly over-lapping) through the selected switch mounting surface per the attached template.
Ensure the template is oriented correctly because it is
not symmetrical. Also, drill four appropriate sized holes
for the fasteners selected to secure the switch panel to
its mounting surface.

The Jabsco Quiet-Flush Toilet does not require routine
maintenance other than occasional cleaning to maintain
a hygienic sanitary condition. Clean toilet with mild
nonabrasive cleaners without strong aromatics. Cleaners
having high concentrations of aromatics such as pine
scented concentrated cleaners and strongly scented
degreaser concentrates can cause the pump’s seal to
swell and may contribute to a premature seal leak.
The toilet has no wearing parts that need periodic
replacement other than the shaft seal which, under
normal conditions, should provide several years of
service before needing replacement. The seal only
requires replacement if signs of leakage are noticed
under the seal housing positioned between the motor
and toilet base assembly.

Notice: Before performing any service, disconnect the
power supply to the toilet and take precaution to ensure
it
is not reconnected until the service is complete. Also,
pump all water from the toilet bowl and if connected to an
overboard discharge, close the discharge seacock.
the motor and slide the seal housing onto the motor shaft
until it is against the motor end bell. Position a new plastic seal washer under the head of each of the flat head
seal housing retainer screws and secure the seal housing to the motor. Slide the centrifugal impeller on the
motor shaft positioning it about 1/32" (1mm) from the
seal housing and secure it to the shaft with the set screw.
Rotate the impeller to ensure it does not rub on the seal
housing.
Slide the macerator housing over the motor shaft, place
the lock washer on the end of the shaft and screw the
chopper onto the shaft. Tighten the chopper while holding the motor shaft at the rear of the motor. Position a
new O-ring in the seal housing O-ring groove (it may be
retained in the groove with a small amount of grease).
Slide the pump assembly into the toilet base ensuring
the macerator housing is properly positioned within the
base. The cut-out in the side of the macerator housing
must align with the
discharge port in the base (the macerator housing is keyed so it will only go in when properly positioned). Ensuring the O-ring is still properly positioned in the O-ring groove in the seal housing, place the
pump assembly against the base and secure it in place
with the four screws and lock washers. Replace the white
motor cover by snapping it down over the pump motor.
To replace the shaft seal, snap off the white motor cover
and remove the pump assembly by removing the four
screws with lock washers that secure it to the toilet base.
Carefully slide the pump assembly from the base
ensuring the macerator housing also slides out of the
base with the pump.
The pump chopper will engage the macerator housing
and it may be necessary to gently tap the chopper
against the macerator housing to free it from the base.
Prevent the motor shaft from turning by inserting a
screwdriver in the shaft slot at the rear of the motor and
unscrew the nut retaining the chopper blade. Remove
the chopper and macerator housing from the motor
shaft. Remove the O-ring from the O-ring groove around
the outer diameter of the seal housing. With
an allen
wrench, loosen the centrifugal impeller set screw and
slide the impeller off the shaft. Remove the two screws
that secure the seal housing to the motor and slide the
housing off the motor shaft. Remove the two seal washers from under the head of each of the two seal housing
retainer screws. With a pair of needle nose pliers grasp
the shaft seal and pull it from the seal housing. Clean all
parts and inspect for damage.
Lubricate the OD of the new seal with a small amount of
water and press it into the seal bore with the seal’s lip
facing the threaded end of the shaft. Do not use the
stainless steel star retaining washer supplied with the
seal. Lubricate the ID of the seal and the motor shaft with
a small amount of water resistant grease. Ensure the
