Only things which were eaten or drunk, or the toilet paper supplied
with the boat, should be put in the heads! Facial tissues, tampons,
and other foreign matter will clog the system. If these heads are
used properly, they are quite reliable. Failures are virtually always
due to mis-use!
4P3: Head Problems
The only likely head problem is easy to diagnose, for you will hear the head pump run frequently
or not stop, and you will see that no water remains in the bowl. This indicates that the ball valve is not
sealing the bottom of the head properly! Most often this is due to "wimpy" operation of the head pedal:
press and release it with prompt foot motions so that the seal is completely closed after use. If re-
flushing does not make the seal perform properly, then, while holding the pedal down, run your finger
around the inside of the seal opening to be sure no grit or other foreign matter has become imbedded
in the seal; if it has, remove it, and try the seal again.
Remember, the two head systems are completely separate: If you have trouble, turn off the
faulty head and use just the other head; call NWE for assistance.
Of course, if a holding tank is full, that head cannot work! Pump the holding tank (see below)
when required!
4P4: Holding Tank
There are two 28-gallon holding tanks. Unless the Y-valves are set so the heads pump
overboard (see below), the sewage from each head goes to its holding tank.
4P5: Holding Tank Pumpout & Macerator Pump
The sewage from each head goes to a holding tank. If dumped
overboard from this tank, the effluent passes through a through-hull valve
(normally open) near it.
To dump a tank, connect a shore pumpout hose to the selected
"Waste" deck fitting located on each side deck.
In some Canadian waters (but not in a "no-discharge zone"), you can
dump the tank overboard without a pumpout station by taking two steps:
1) Turn "ON" the correct macerator pump DC panel breaker;
2) Press the momentary switch (see photo); the pump will run for
two minutes, about enough to empty one-half of the tank;
3) Check that tank's indicator to see if it's empty. If it is not, repeat steps (2) and (3).
It takes about ten minutes to empty a full holding tank. The best way to monitor it is to run it
until bubbles come out from under the starboard side of the hull.
