INSTALLATION

The 37245-Series Quiet Flush Toilet is complete with a

dedicated  PAR-MAX 2.9  pump  to  provide  either  sea  or

lake water to rinse the toilet bowl when flushing the toi-

let. This pump is intended to be located remotely from

the toilet but will function best if the distance from the toi-

let  is  kept  to  a  minimum.  Because  it  is  self-priming,  it

may be located above the vessel’s waterline. It must be

installed with the Pumpgard strainer (provided with the

toilet)  located  somewhere  in  the  inlet  plumbing  to  the

pump. The toilet also includes a multi-function flush con-

trol which should be installed in a bulkhead location that

is convenient to the toilet and allows access for wiring to

run  from  the  power  source  and  to  both  the  toilet  dis-

charge pump and the PAR-MAX rinse water pump.
Install the toilet seat and lid assembly on the china bowl

with the fasteners provided and position the toilet in its

desired location. When locating the toilet, ensure there is

adequate clearance above and to the rear of the bowl so

the seat and lid assembly can rotate slightly past vertical

so it will remain up when lifted. It is all right to rotate the

waste pump assembly under the china bowl to provide

clearance  from  possible  obstructions,  if  desired.  This

can be accomplished by removing the four white plastic

hex head caps from the nuts at the base of the china

bowl  and  removing  the  four  machine  screws  and  nuts

that secure the china bowl to the base. The base can

then be reattached to the bowl at any position in 90º in-

crements. Once the exact position for the toilet has been

determined, mark the location of the four base attach-

ment holes on the toilet mounting surface. Determine the

best toilet attachment method using 5/16

" (8 mm) fas-

teners (either machine screws for through bolting or lag

screws for topside attachment) and drill the appropriate

size holes for the fasteners being used. If securing the

toilet with lag screws into a plywood underlayment below

fiberglass, be sure to drill a hole through just the fiber-

glass layer large enough to allow clearance for the screw

threads and shank to avoid cracking the fiberglass.
The  PAR-MAX  pump  should  be  mounted  to  a  solid

mounting surface. It should be secured with four fasten-

ers  through  the  rubber  grommets  that  snap  into  the

pump’s base. Do not over-tighten the mounting screws

and crush the grommets such that they will not absorb

vibration.  The  pump  may  be  mounted  in  any  position;

however, if mounting it to a vertical surface it should be

oriented so water dripping from a loose port connection

will not drip down on the motor. Plumbing runs should be

kept  as  short  and  straight  as  possible.  All  plumbing

should be completed with quality 3/4

" (19 mm) hose that

will not collapse or kink. Route the inlet hose from a 3/4

"

(19  mm)  through  hull  and  seacock  fitting  located  well

below the waterline (and well forward of any discharge

through hulls, if installed) to the pump inlet port. Ensure

the  inlet  hose  passes  through  an  accessible  location

(preferably above the vessel’s waterline) that will allow

for the installation of the Toilet Pumpgard strainer where

it can be periodically inspected and cleaned of debris.

The Pumpgard strainer should be secured with two fas-

teners to a solid mounting surface with the flow arrow

pointing towards the pump. The inlet hose should be cut

and each end attached to the strainer’s ports. The hose

from the strainer’s discharge port must connect with the

PAR-MAX pump’s inlet port. Provided with the toilet is a

six  foot  length  of  smooth  white  aesthetically  pleasing

hose  to  connect  to  the  back  of  the  toilet  bowl  and  be

routed out of the head area. Ideally, the PAR-MAX pump

should be located so this length of hose can be connect-

ed  directly  to  the  pump’s  discharge  port  avoiding  an

additional splice to the hose leading from the pump to

the back of the toilet bowl. If this is not practical, acquire

a 3/4

" (19 mm) barb to barb hose mender and splice the

white hose to the supply hose from the discharge port of

the pump.

If the toilet is installed below the vessel’s waterline, in

order to prevent a siphon action from filling the toilet, a

properly positioned vented loop fitting must be installed

between the PAR-MAX pump and the back of the toilet

bowl. The vented loop fitting must be secured in a loca-

tion that remains at least 6-8 inches (15-20 cm) above

the waterline at all angles of heel and trim (see diagram). 

The toilet discharge port is sized for 1

" (25 mm) hose.

The discharge hose should be a quality grade reinforced

hose  suitable  for  waste  applications.  Route  the  dis-

charge hose to the holding tank in the most direct way

with as few bends as possible. To retain some water in

the bowl, it is best to loop the discharge hose up about

8-10 inches (15-20 cm) as close to the toilet as practical

then on to the holding tank. It is best to avoid any dips or

low  spots  in  the  discharge  plumbing  that  can  act  as

water traps and collect waste. If this occurs, waste can

solidify and cause a discharge blockage.
If the toilet is plumbed to an overboard discharge, and is

below  the  vessel’s  waterline,  the  discharge  plumbing

must  include  a  properly  positioned  vented  loop.  The

vented  loop  fitting  must  be  secured  in  a  location  that

Flood hazard.  If toilet is installed below the

waterline, it must be installed with a properly

positioned vented loop in the discharge hose. 

Failure to do so can result in flooding which

can cause loss of property and life.
