3. Cleaning

Caution:  Do  NOT  use  aggressive  chemical 
agents such as Acetone or Bleach because 
plastic  parts  may  crack  and  the  enamel 
coating on the seat and lid may blister.

To clean the bowl, use any liquid or cream ceramic 

• 

cleaner.
To clean the rest of the toilet, including the seat and lid, 

• 

use a non-abrasive liquid cleaner. Polish with a dry cloth 
only.

CAUTION: Do not use abrasive pads on any 
part  of  the  toilet  and  do  not  use  cream 
cleaners except for the bowl.

 

• 

To disinfect the toilet, use a liquid disinfectant diluted in 
accordance with the manufacturer's instructions. You 
may apply it to all parts of the toilet using a sponge or 
soft brush as necessary.

CAUTION:  Do  not  use  thick  liquid  toilet 
cleansers or neat bleach. They may damage 
the  valves,  gaskets,  seals  and  the  enamel 
coating of the seat and lid.

Servicing Instructions 

Jabsco  manual  toilets  do  not  normally  require  maintenance 
during  the  season,  provided  that  they  are  winterised  in  the 
autumn and overhauled in the spring. However, any toilet will 
benefit from:

Thorough flushing - refer to OPERATING 

• 

INSTRUCTIONS for NORMAL USE.
Regular use - if not used regularly lubrication is 

• 

beneficial - refer to OPERATING INSTRUCTIONS for 
FIRST USE.
Regularly check all fastenings for tightness and leaks.

• 

HAZARD RISK - Leaks

If the toilet is connected to ANY through-hull fittings and, if the 
toilet or the pipework develops a minor leak, it can suddenly 
become a major leak that allows water to flood in, causing the 
craft to sink, which may result in loss of life.  Therefore, if ANY 
leak develops you MUST repair it immediately.

REPAIR LEAKS IMMEDIATELY!

1. Servicing & Winterisation - preparation

Jabsco manual toilets are designed to be user serviceable and 
no special skills or tools are required.

Flush the toilet in accordance with the OPERATING 

• 

INSTRUCTIONS for NORMAL USE and, in particular, 
ensure that all waste has left the discharge pipework and 
that the bowl is empty.
CLOSE BOTH SEACOCKS (even if secondary valves 

• 

are fitted)
If the vessel is being wintered afloat, WIRE SEACOCKS 

• 

SHUT
Be ready to mop up any water that may come out of the 

• 

system.

2. Servicing - Seal replacement

If water begins to leak around the piston rod (key 29) at the top 
of the pump, the seal assembly (key 18) is worn and must be 
replaced.
YOU WILL need:

  A Seal housing Assembly 29044-3000.

Unscrew the seal housing assembly (key 18) using a 

• 

24mm (15/16") spanner and remove the entire piston rod 
assembly from the toilet.
Wrap some tape around the piston rod within 16mm (

• 

5/8") 

of the handle. Grip the piston rod through the tape, 
unscrew the handle and remove the bumper washer (key 
25). Remove the tape.
Slide the old seal assembly off the piston rod. Wrap one 

• 

turn of tape around the thread at the top of the piston 
rod to protect the new seal and slide the new seal 
assembly onto the piston rod. Remove the tape from the 
thread.
Wrap some tape around the piston rod within 16mm (

• 

5/8") 

of the handle. Grip the piston rod through the tape and 
replace the bumper washer and handle. Remove the tape 
from the piston rod.
Slide the whole assembly back into the pump cylinder 

• 

and tighten in place.

CAUTION: Gripping the piston rod with a tool 
anywhere except on the 16mm (5/8") below 
the  handle  damages  the  surface  in  a  way 
that causes rapid seal failure.

3. Servicing - Winterisation

Drain  the  complete  system,  both  as  protection  against  frost 
damage  and  to  discourage  the  growth  in  the  pipework  of 
anaerobic bacteria that cause unpleasant smells.

Open any secondary valves.

• 

Remove the base drain plug (key 8).

• 

Disconnect the discharge flange (key 32) from the pump 

• 

(avoiding the need to remove the hose from the 
discharge elbow (key 34).
Loosen hose clips and disconnect the hose ends from 

• 

both seacock hose tails. Pump the handle (key 17) to 
drain the toilet pump and ensure that all water is drained 
from the toilet system.

CAUTION:  The  use  of  anti-freeze  is  NOT 
RECOMMENDED,  as  it  is  impossible  to 
ensure that it penetrates the complete toilet 
system. If, for any reason, anti-freeze is used 
it MUST be glycol based.

If you plan to overhaul the toilet in the spring, this is a good time 
to disassemble it and take the components ashore to make the 
overhaul easier.

HAZARD  RISK  -  Seacocks  opened  by 
mistake

If you leave the toilet disassembled and, if the seacocks are 
opened  when  the  craft  is  afloat,  water  will  flood  in  and  may 
cause the craft to sink, which may result in loss of life.
Therefore, you MUST attach a warning notice to the seacocks 
and, if possible, wire the seacocks shut.
