opened to drain the tank.
Water Heater Draining
All models have a drain plug or petcock on the water heater. Access is from the
exterior. The plug or valve is usually located in the lower left corner, viewed as
you face the exterior of the water heater.
WATER VALVES
Your Airstream has 4 in-line water shut off valves. One is for the water purifier,
two are for shutting off the cold water supply to the toilet and exterior water
service, one is for bypassing the water heater when winterizing using the antifreeze
method as explained in the winterizing section of this manual.
The water heater by-pass valve is located on the water heater, accessed inside
the lavatory cabinet by opening the cabinet door or removing the cabinet
drawer, by opening the roadside exterior compartment door or removing the
wardrobe shelf.
Plumbing
A water purifier shut off valve is located under the galley top on the water feed
line to the purifier cartridge.
On all units except the front bed models an exterior water service shut off valve
is located inside the lavatory cabinet and can be accessed by either opening
the cabinet doors or removing the cabinet drawers. The front bed models shut
off valve is accessed by removing the access panel on the wardrobe bottom
shelf. The exterior water service is located beyond the heated area of the trailer
and can be damaged if the water is not turned off in freezing temperatures. In
freezing temperatures close the shut off the valve and open the exterior water
service valve to drain the valve and line.
There may be one, two, or three valves located inside the lavatory cabinet
according to your model length. If there are more than one, one of valves is
used as the water heater by-pass system as explained above and is easily
recognizable as it will be located on the back of the water heater. Another may
be for the toilet shut off. The third valve is for the exterior water service. Always
check to see if the water supply has been cut to the exterior service before
using the rest of the water system in freezing weather.

service situation. On some units it is located inside the lavatory cabinet, on
most units it is located just behind the toilet close to the floor.
