4P3: Head Problems
The only likely head problem is a clogged head or a full holding tank. Use the other
one... 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; in this case, the toilet has a
“shutdown relay” and stops operating! Pump the holding tank (see below) when required!
4P3: Holding Tank
There are two 35-gallon holding tanks. Unless the Y-valves are set so the heads
pump overboard (see above), the sewage from each head goes to its holding tank.
4P4: 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 the tank, use a shore side pumpout station connecting to the “Waste” deck
fitting connected to each holding tank, 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 turning “ON” both macerator pumps at the DC panel
and rotating the macerator timer (located to the right of the helm wheel) to the appropriate
amount of time. It takes about 4 minutes to empty full holding tanks using the macerator
pump. Do not leave the pump running dry for a long time as it will damage the pump!
4P5: Head Holding Tank Level Gauge
The boat is equipped with a tank level indicator on each
holding tank, so it is easy to tell if a tank is full. Check this indicator
regularly and don’t flush if full! In the guest head, the indicator is simply
a red light...there is room for one or two more flushes!
4P6: Head Y-Valves
Each head is equipped with a Y-valve.
The aft one is in the Master Stateroom in the sink
cabinet of the master stateroom; the forward one
is under the hatch in the companionway. Each
Y-valve is labeled "Tank"/"Sea" indicating the type of discharge. In US.
Waters, the Coast Guard Rules require that the valves be "secured" in
the holding tank position to assure that all effluent will be kept aboard in
the tank. If you turn the valve to overboard while in Canadian waters,
re-secure it with the wire ties supplied and stored near the valve when
you return to the U.S.! (More next page)
