The decomposition of waste produces a
colorless, odorless gas, methane, that is lighter
than air, combusti ble, and ex treme ly le thal.
Always provide sufficient ventila tion when
effecting repairs to the waste sys tem and allow
no odor from the waste system to go
unresolved.
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.
NOTICE
Fail ure to keep the water tank vent fit tings clean
will cause ex ces sive pres sure build up with in the
tank dur ing fill ing. This can cause wa ter tank
dam age.
Periodically remove the filter screens from the faucet
discharge spouts and shower head. Re move the
accumula tion 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
restric tion to cause the pump to cycle on and off.
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 re place the part. The
filter unit will twist apart.
Inspect and clean the shower sump every 30 days.
Some water will always be in the com part ment.
Se diment and other debris will buildup and affect the
auto matic bilge switch and pump opera tion. Remove
the pump's cover and clean the screen. The screen
will become blocked and the pump will not operate
properly. To clean the compartment, use baking soda
and a fine wire brush to re m ove dirt and other debris.
This will also serve to disinfect the area.
B. Winterizing the Water System
Winter lay-up service procedures should include a
thorough draining of the water system. Discon nect all
accessible fittings. Blow out all lines. Be sure the hot
water heater, fresh and gray water tanks, transom

shower, pumps and lines are com pletely dry. Leave
all faucets open. Freez ing water can cause severe
damage to all water system compo nents.
NOTICE
Always winterize the fresh water system prior to
winter ization of the hull drainage (bilge pump)
system.
Draining the system as mentioned can be very tedious
and an incomplete job can result in expen sive repairs.
The use of nontoxic antifreeze (such as RV antifreeze)
designed for fresh water sys tems consider ably
reduces the work necessary and is a more positive
means of winteriz ing the system. Follow the direc tions
included with the antifreeze solution.
To winterize:
1. Turn on the water pump and drain the water tank
by opening a fau cet (the pump will run faster when
it is empty).
NOTICE
Be sure the circuit breaker for the water heater
in 120 Volt AC panel is in the OFF posi tion.
The water heater will be dam aged immediately
by supplying electrical power to an empty water
heater.
DO NOT run the water pump without water
in the system. Pump damage will result. Be
watchful and turn the pump off as soon as
the tank be comes empty.
2. Add 15 gallons of RV antifreeze to the water tank.
NOTICE
Generally the hot water heater will re quire
approxi mately five gal lons of antifreeze before
the hot water lines will have antifreeze run ning
through them. The cold water faucet should be
turned OFF at some point to test for antifreeze
in the hot water line.
3. Turn ON all faucets (both hot and cold) until
undiluted antifreeze is seen. Make sure the
transom shower, head faucet and galley faucet
have antifreeze coming out.
