Troubleshooting
Toilet system start-up
1. Open the sea water inlet and the toilet
discharge outlet seacocks.
2. Press the Flush switch and hold for at least
10 seconds.
3. Toss several sheets of toilet paper into the
bowl and repeat the cycle. The bowl should
completely clear.
Normal flushing
Press the Flush switch down and hold until the
waste drains from the toilet bowl (about 10-20
seconds).
• To use less water for liquid-only flushes, press
the Flush switch for a shorter period of time.
• If the toilet bowl does not completely
flush and fills up with sea water during the
flush, partially close the inlet valve until the
bowl clears and completely discharges the
effluent. Then, with the inlet and discharge
valves completely open, flush the toilet for a
few seconds to clear the toilet and discharge
system.
The switch activates a macerator pump that
siphons water and waste from the bowl,
macerates, and propels the effluent to the
discharge line.

non-use
NOTICE: During the water evacuation process,
do not operate the sea water pump very long

Problem
The flush function
works, but the water
in the bowl empties
slowly or not at all.
The macerator pump
makes unusually loud
noises or continually
trips the circuit breaker.

Possible cause
The discharge piping is pinched
or kinked.
The discharge piping is too
high. All upward vertical loops
should not exceed a total of 4 ft
(1.2 m) in height.
The macerator pump or
discharge piping is blocked.
There is foreign material in the
pump chamber.
without water. The pump impeller may become
damaged.
The macerator toilet and sanitation hoses should
be protected if the toilet will not be needed
for an extended period of time (more than two
weeks, especially in hot weather).
1. Flush the toilet and add 4 oz (118 ml)
of liquid biodegradable laundry
detergent (should not contain bleach or
environmentally harmful substances).
– If using sea water for flushing, shut off the
power to the sea water pump and add
fresh water directly into the bowl during
the flush cycle.
2. Flush the toilet at least five times.
3. Turn off the water supply to the toilet.
4. Flush the toilet without water very briefly
to evacuate all water. This procedure
will minimize any remaining water in the
macerator pump.
5. Turn of the power to the toilet.
6. After extended periods of non-use, the toilet
and pump may be dry. For an easier restart
of the toilet system, add 1 qt (0.9 L) of water
to the bowl and let it stand for a few minutes
before use.
Recommended solution
Check the discharge piping.
Reroute the discharge piping.
Close the seacocks and clear any
blockage.
Close the seacocks and clear any
foreign material.
