The waste holding tank should be emptied upon visual J - 7 SYSTEM MAINTENANCE
inspection of the waste holding tank and determining
the waste holding tank’s capacity is almost full or by
using the waste level indicator if so equipped. Waste
level indicators are typically located in the head. DO
NOT ALLOW THE WASTE TANK TO BECOME
OVERFILLED.
Information supplied with water and waste system
components by the equipment manufacturers is
included with this manual. Refer to this literature for
additional operation and service information.
Be sure the batteries in the boat are properly charged.
Operating the pressure pump from a battery with a
low charge will result in pump cycling. This could lead
to premature pump failure.
To pump out the holding tank:
1.
2.
Be sure the head has some water in the bowl.
Connect the dockside pump out connection to the
WASTE plate located on the deck.
The decomposition of waste produces a
colorless, odorless gas, methane, that is lighter
than air, combustible, and extremely lethal.
Always provide sufficient ventilation when
effecting repairs to the waste system and allow
no odor from the waste system to go
unresolved.
NOTICE
Usually the dockside pump out connection will
screw into the waste deck plate or has a
rubber sleeve that inserts into the plate and
must be held in position during the pump out
operation. If the hose is not air tight or connect-
ed properly, waste could spurt out or leak
around the deck fitting and into the boat.
A. Clean Vents and Screens
Periodically, inspect the water tank vents and thru-hull
vent fittings for any dirt, wax, etc. Carefully remove
any obstruction with a pipe cleaner or similar device.
Be sure not to puncture the screen. The stainless
steel vent cap is not removable.
3.
4.
Have the pumping station operator activate the
pumping equipment. The waste will be drawn from
the holding tank and into the pumping station’s
disposal tank.
Remove the pump out connection from the deck
plate. Add at least 5 gallons of clean water to the
holding tank on most models through the waste
deck fitting using a dockside water hose.
NOTICE
Failure to keep the water tank vent fittings
clean will cause excessive pressure buildup
within the tank during filling. This can cause
water tank damage.
5.
6.
Repeat steps 2 & 3 above to pump out the water
used in step 4 to flush the holding tank.
Periodically remove the filter screens from the faucet
discharge spouts and shower head. Remove the
accumulation of sediment from the screens. If neces-
sary, clean out the holes using a fine wire. A buildup
of debris in the faucet filter screens can create enough
restriction to cause the pump to cycle on and off.
Add waste holding tank treatment chemical to the
head bowl. It is available from the dockside
pumping station or can be obtained from your
dealer. Flush at least twice.
Be careful when handling and storing
treatment chemicals. Not only are they toxic,
but they will also stain and damage
surrounding surface.
Check the in-line water filter/screen for sediment and
blockage. It is located between the water tank and
the pressure water pump. If obstructed, remove from
the water line and either clean or replace the part.
The filter unit will twist apart.
