Water Hose Storage
Water System
The Airstream water system provides full
service both when the trailer is self-contained
or when city water is available. Water heater
capacity is 10 U. S. gallons in 27-ft. through
31-ft. units and 6 gallons in 21 ft. through 25
ft. units. 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.
City Water Hook-Up
For city water supply, connect a 1/2" mini¬
mum high pressure hose to the water inlet
fitting (see photograph) located under the
rear roadside comer of the trailer, just for¬
ward 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. The drain valve is access¬
ible through a hole in the floor below the
galley sink. 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 photo) on the
exterior wall adjacent to the galley, and fill
with a hose or a bucket, until the water
supply pipe is overflowing. 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 the drain valve and running fresh
water through it.
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
(514 or 6%) in the ratio of 1/4 cup of
bleach to 1 gallon of water. (Common
