4P3: Head Problems
The two head systems are completely separate: If you have trouble, turn off the faulty head
and use just the other head; call for assistance. Of course, if the holding tank is full, the heads cannot
work! Pump the holding tank (see below) when required
4P4: Holding Tank
There is a 30-gallon holding tank on the boat located in the engine room to starboard of the
engines. Unless the Y-valves are set so the heads pump overboard, the sewage from each head goes
to the holding tank. If dumped overboard from this tank, the effluent passes through a through-hull
valve (normally open) just aft of the holding tank in the engine room on the starboard side of the boat.
4P5: Head Holding Tank Level Gauge
The boat is equipped with a tank level indicator in the aft head compartment, so it is easy to tell
if a tank is full. Check this indicator regularly and don’t flush if full!
Note that after a few uses, the
“empty” light will extinguish, and no light will be lit until the tank reaches the “mid” position.
4P7: Head Holding Tank Pumpout
If dumped overboard from this tank, the effluent passes through a through-hull valve which is
normally in the correct position. To dump the tank, use a shore side pump out station connecting to the
"Waste" deck fitting on the side deck.
4P6: Head Waste Overboard Pump
If not in U.S. waters or a "no-discharge zone", you can dump the tank overboard without a
pump out station by turning "ON" the macerator pump at the DC panel. Leave it on until either the
“empty” indicator LED shows on the tank level unit in the rear head compartment, or until you see
bubbles coming fron under the boat.
It takes about ten minutes to empty a full holding tank.
If it is emptied while underway, have someone monitor the operation,
checking the tank level indicator to be sure that the pump is not forgotten and
left running, lest you ruin the pump!
4P8: Head Y-Valves
The heads are equipped with Y-valves, both in the engine room. The aft head Y-valve is aft on
the port side near the fuel tank; the forward head Y-valve is on the forward engine room bulkhead to
starboard.
