Routine maintenance
Monthly
1. Inspect toilet, plumbing, and plumbing connections, wires,
wire connections, and the in-line filter.
2. Open and close all plumbing valves, including seacocks.
3. Check in-line water filters and vented loops for blockage.
Yearly
Check water valve filter. Also check water valve filter if water
flow into toilet becomes insufficient.
During extended periods of non-use
The macerator toilet and sanitation hoses should be protected
if toilet will not be needed for an extended period of time (more
than two weeks, especially in hot weather).
1. Flush toilet and add 4 oz. (118 ml) of liquid biodegradable
laundry detergent (the detergent should NOT con tain bleach
or environmentally harmful substances).
Note: If using sea water for flushing, shut off power to sea
water pump and add fresh water directly into the bowl during
the flush cycle.
2. Flush toilet at least five times.
3. Turn off water supply to 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 off power to the toilet.
6. After extended periods of non-use, toilet and pump may dry.
For easier re-start of toilet system, add one quart of water to
the bowl and let it stand for a few minutes before use.
During water evacuation process, do not operate sea water pump
very long without water. Pump impeller may become damaged.
Winterizing Toilet System
At the end of each season, the macerator toilet should be
winterized for storage by using potable water-safe antifreeze (if
boat will be exposed to freezing temperatures).
If system will be subjected to freezing temperatures, please
follow procedures in this section, “During extended periods of
non-use”, and then winterize system as described here.
NOTE: Use nontoxic antifreeze designated for potable water systems.
