Disinfecting Fresh Water Systems - Winnebago Sunflyer Owner's Manual

PLUMBING SYSTEMS
2. Attach a hose from the external water source
to the city water connection in the utility
compartment on the left side of your vehicle.
3. Turn on the city water faucet.
When connected to an outside source of
water, the water bypasses the demand pump and
storage tank and supplies pressure directly to
individual faucets and toilet.
NOTE: Always keep the tank fill valve pointed to
"City Water" unless you are filling the
water tank. If this valve is pointing to
"Water Tank" while using city water, the
water will keep flowing into the tank and
out onto the ground through the tank vent
tube.
A passage or hatch is provided in the bottom
of the compartment to route the hose through so
you can close the compartment door during use.
A hose elbow, available from most RV sup-
pliers, may be added (see photo) to avoid kink-
ing the city water hose when the compartment
door is closed.
To disconnect from the external source:
1. Turn the external source off.
2. Open a faucet inside the vehicle to relieve
line pressure.
3. Disconnect the hose from the coach.
4. Replace the protective plug back into the
threaded collar on the connection.

DISINFECTING FRESH WATER
SYSTEMS ON RECREATION
VEHICLES
(As approved by the U.S. Public Health
Service)
To assure complete disinfection of your fresh
water system, it is recommended that the follow-
ing procedure be followed on a new system, one
that has not been used for a period of time, or
one that may have become contaminated. This
procedure is also recommended before long
periods of storage such as over winter.
1. Prepare a chlorine solution using 1 gallon of
water and 1/4 cup of household bleach
(sodium hypochlorite solution). With tank
empty, pour chlorine solution into the tank.
Use 1 gallon solution for each 15 gallons of
tank capacity. This procedure will result in a
residual chlorine concentration of 50 ppm in
the water system. If a 100 ppm concentration
is required as discussed in item 3, use 1/2
cup of household bleach with 1 gallon of
water to prepare the chlorine solution. One
gallon of the solution should be used for
each 15 gallons of tank capacity.
2. Complete filling of tank with fresh water.
Open each faucet and run the water until a
distinct odor of chlorine can be detected in
the water discharged. Do not forget the hot
water taps.
3. Allow the system to 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
should be permitted to stand in the system
for at least 1 hour.
4. Drain and flush with fresh water.
WARNING
Chlorine is poisonous - recap bottle
and clean utensils after use.
Never use automotive type antifreeze
in your potable water system as it is
poisonous.
