HOLDING TANK
Waste from the toilet is flushed to the holding tank. You can empty the holding tank
using a dockside pump-out or, when permitted, by using the macerator to discharge
the waste directly overboard. Waste in the holding tank can produce methane, an
explosive gas. Keep vent open and clear of obstructions.
Explosion or fire hazard from the accumulation of explosive gases
can cause death or serious injury. Keep vent open and clear of
obstructions and keep open flame away when maintaining
sanitary system.
Check the level of the waste tank regularly. When the tank is full, do not use the
head. If the tank is overfilled, waste can plug the vent or cause the tank to rupture,
allowing the waste to empty into the bilge area. Make sure to check the tank
regularly.
To empty the holding tank, connect the hose from the pump-out facility to the fitting
marked WASTE. After the waste is pumped out, flush the head several times to clear
waste buildup of the lines and rinse out the tank.
Flushing fresh water through the head is also a good idea if you will be leaving the
craft unattended for a few days. Flushing will clear waste from the lines into the
holding tank. Any waste in the lines tends to dry out and the hardened waste can
affect the future operation because it can decrease the inside diameter of the lines.
