Water System - Airstream Caravanner 1977 Owner's Manual

Water System
The Airstream water system provides
full service both when the trailer is self-
contained or when city water is avail¬
able.
Water heater capacity is 6 gallons.
The water tank stores 45 gallons of clean
fresh water for all your needs.
When self-contained,
the water pump
should be turned on. The switch is located
on the Central Control Panel in the galley
roof locker of your Airstream. The water
pump will run whenever a faucet is opened,
and will shut off whenever a faucet is
closed. It will deliver 3 gallons per minute
under constant pressure.
Note: The water pump must be turned
off when hooked up to city water supply
and when you leave your Airstream
unattended.
The
water pump and filter
are under the
galley adjacent to the furnace. The filter
screen should be cleaned periodically to
prevent accumulation of dirt and sand. To
remove the screen, disconnect the rubber
hoses from both ends, separate the screen
housing, remove the screen, dean and
replace.
For city water supply, connect a
1
/
2
" mini¬
mum high pressure hose to the water inlet
fitting (see Figs. 1 and 2) located under the
rear roadside corner of the trailer just
forward of the bumper. Turn the hose on
and slowly open an inside faucet until the
water flows free of air. The system will now
be ready for use. If you are staying for
some time where city water is available,
drain the water storage tank. To drain the
tank, open a dram valve or faucet and turn
the water pump switch on until the tank is
empty. Be sure to refill the tank with fresh
water before departing. The system has
check valves in the water lines to protect
the water tank while you are connected to
the city water supply.
The water tank
is located under the floor
just forward of the axle. To fill the water
storage tank, open the filler spout (see Fig.
3, page 74) on the exterior wall adjacent to
the galley, and fill with a hose or a bucket.
Close and lock the spout and the water
system is ready to use.
To clean the tank, pour some bicarbonate
of soda into the filler spout with several
gallons of water and allow to stand for a
minimum of four hours. Then flush the tank
out by opening a faucet, allowing the water
pump to drain the system. Then refill with
fresh drinking water. If the water tank must
be cleaned further, the following procedure
is recommended.
1. Prepare a sodium hypochlorite solution
using potable water and household
bleach (5V4 or 6%) in the ratio of V4 cup
of bleach to 1 gallon of water. (Common
household bleaches are Purex and
Chlorox.)
2. Pour 1 gallon of hypochlorite solution for
each 15 gallons of capacity into the
empty water tank.
3. Add enough fresh drinking water to
completely fill the water system.
4. Allow closed system to stand for three
hours.
