The vessel is equipped with two fresh water electric marine Tecma toilets. Each toilet has an adjacent
control panel with two buttons. The button on the left is labeled “BEFORE USE”; the button on the
right is labeled “AFTER USE”. To conserve water, the following procedures are highly recommended.
For urination, simply use the toilet and then press the “AFTER USE” button. For solid human waste,
first press the “BEFORE USE” button to pre-fill the bowl. When you are done, press the “AFTER USE”
button. A few seconds after the flush a macerator pump will move the effluent to the holding tank.
To recap:
• For #1, “AFTER USE” button ONLY.
• For #2, “BEFORE USE” button first; “AFTER USE” button when mission accomplished.
It is important that every member of the crew be informed on the proper use of the MARINE TOILET.
The valves, openings, and pumps are small and may clog easily. If the toilet clogs, it is YOUR
RESONSIBILITY!
Always pump the head for children, so you can make sure nothing foreign is being flushed.
Caution – Never put paper towels, tampons, Kleenex, sanitary napkins, household toilet paper, or food
into the marine toilet. Use only the special dissolving marine toilet tissue provided by AYC.
The TOILET THRU-HULL is located under the forward cabin’s sole. The valves are set up so that the
toilets discharge ONLY INTO THE HOLDING TANK. Do not change any of the Y-valves.
Holding Tank
The sanitation HOLDING TANK holds approximately 60 gallons. Be aware of the rate of waste
production (about 1 gallon per flush). With an overfilled tank, it is possible to break a hose, clog a vent,
or burst the tank. The result will be indescribable catastrophe and an EXPENSIVE FIX to you. Empty
the tank EVERY OTHER DAY to avoid this problem. Please check on the local regulations for where
discharging is allowed (this is your responsibility). No discharge is allowed in US waters and only in
certain areas in Canada. Manage the holding tank capacity by using shore facilities whenever possible
and by monitoring the level of the tank.
The HOLDING TANK is located under the sole in the forward stateroom. There is a Tank Watch holding
tank indicator with four indicator lights (“Empty”, “Low”, “Mid”, and “Full”) located at the main lower
helm station, but do not rely totally upon these as they often get clogged. When the “Mid” indicator
light comes on, plan on pumping out as soon as possible. You should never see the “Full” indicator
light! If you do, the tank is truly full. Do NOT flush even once.
