WASTE PUMP SERVICE

The Jabsco Quiet-Flush Toilet does not require routine

maintenance other than occasional cleaning to maintain 

a  hygienic  sanitary  condition.  Clean  toilet  with  mild 

non-abrasive cleaners without strong aromatics. Clean-

ers  having  high  concentrations  of  aromatics  such  as

pine scented concentrated cleaners and strongly scent-

ed 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 nor-

mal 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,  turn  off  the 

electrical power to the toilet and rinse water pump. Take

precaution to ensure it is not turned on until the service

is complete. Also, pump all water from the toilet bowl and

if connected to an overboard discharge, close the dis-

charge seacock.
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 hous-

ing  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. Remove the chopper blade and mac-

erator 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 centrifu-

gal 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 slinger is properly positioned on the motor shaft next

to 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

" (1 mm) 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 chopper plate on the end of the shaft and screw the

locking nut onto the shaft. Tighten the nut 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.
