Disinfecting Your Fresh Water System; Shower Hose Vacuum Breaker - Winnebago 2009 Adventurer Operator's Manual

• See Winterization Procedure at the end of this
section. Also see filter manufacturer's
information in your InfoCase for further
instructions or precautions.
• When removing the coach from storage,
always disinfect and flush the water system
thoroughly before installing a new filter.
DISINFECTING YOUR FRESH
WATER SYSTEM
To assure complete disinfection of the potable
water system, it is recommended that the
following procedure be followed on a new
system, one that has not been used for a period of
time, or one that could have become
contaminated.
This procedure is also recommended before
long periods of storage such as over winter.
WARNING
Chlorine is poisonous. Recap bottle and
clean all utensils after use.
City Water Hose Disinfection
NOTE: This procedure can be used periodically
to sanitize the city water hose, and can
be used as an alternate method of adding
bleach solution to the fresh water tank if
desired.
1. Connect your city water hose to the fresh
water inlet of your coach.
2. Remove the full-coach filter cartridge from
the filter canister to avoid prematurely
'plugging up' the filter cartridge. Refit empty
canister to filter head for procedure.
3. Hold the "city end" of the water hose upright
and use a funnel to pour 1 1/2 cups of
household chlorine bleach (sodium
hypochlorite solution) into the hose. Keep the
end of the hose held upright to avoid draining
the bleach solution.
4. Connect the hose to a city water hydrant and
turn on slowly, allowing the water to force the
bleach through the hose, then continue filling
the tank with water. (This will disinfect the
city water hose at the same time).
5. Let the system stand at least 4 hours when
disinfecting with 50 ppm residual chlorine.
If a shorter time period is desired, then a 100
ppm chlorine concentration (double the
amount of bleach) should be allowed to stand
in the system for at least 1 hour.
6. Drain the chlorinated water from the fresh
water tank and refill with clean water.
Continuous Tank Disinfection
(Superchlorination)
Some RVers like to ensure continuous
sanitation of their fresh water tank by
"superchlorination"– maintaining an effective
low level of chlorine in the tank at all times.
• Add 1 teaspoon of chlorine bleach (sodium
hypochlorite) to your tank for each 10 gallons
of tank capacity. When you fill the tank, this
will result in a 6.7 ppm level of chlorine,
which should kill harmful bacteria and slime-
forming organisms.
• Chlorine will be removed from drinking water
by the full-coach filter and cold water filter at
the galley.
• Superchlorination does not affect city water
usage, only the fresh water tank.
SHOWER HOSE VACUUM
BREAKER
After using the shower, you may notice water
dripping from the shower faucet assembly. The
dripping results when vacuum in the shower hose
(after closing the shower faucet) slowly releases
and allows water remaining in the hose to drain
down. This is a normal function of the shower
valve assembly and is not a leak or defect.
