External Water Supply - Winnebago 2003 adventurer Owner's Manual

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.

EXTERNAL WATER SUPPLY

("City Water")
To connect to an external source:
1. Turn the water pump switch off.
2. Attach a hose from a city water faucet to the
city water connector in the water center on
PLUMBING SYSTEMS
the left (driver) side of your coach.
3. Turn the water center diverter valve to the
CITY WATER position as shown in the fol-
lowing photo.
4. Open city water faucet. (See following
NOTE for pressure regulator recommenda-
tion.)
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.
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. A check valve built
into the pump prevents water from entering the
pump and filling the storage tank.
NOTE: Because city water pressure varies from
location to location, we recommend
using an in-line water pressure
regulator to prevent damage to any com-
ponents, connections and seals in your
fresh water system. We recommend a
regulator that controls water pressure at
40 psi maximum.
A water pressure regulator may be ob-
tained from any well stocked RV dealer-
ship retail center and some retail
discount centers. These devices simply
