coach for easier access. If you look between

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 five in-line water shut off valves. Two are for shutting off the cold water supply to the
toilet and exterior water service and the other three are for bypassing the water heater when winterizing
using the anti-freeze method as explained in the winterizing section of this manual.
The water heater by-pass valves.may be located in one of two places. Inside the lavatory cabinet, accessed
by opening the cabinet door or removing the cabinet drawer, or by opening the roadside exterior
compartment door. See the winterizing section for their use.
The toilet shut off valve is used to shut water off to the toilet in an emergency or 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.
The exterior water service shut off valve is located on the cold water supply line running inside the lavatory
cabinet and can be accessed by either opening the cabinet doors or removing the cabinet drawers. Since the
exterior water service is located beyond the heated area of the trailer, the exterior valve and its supply line
can be damaged if the water is not turned off in freezing temperatures. In these temperatures shut off the
valve in the lavatory cabinet and open the exterior water service. This drains the water in the so freezing
won’t damage the exterior valve.
There may be one, two, or five valves located inside the lavatory cabinet according to your model length. If
there are more than one, three of valves are used as the water heater by-pass system as explained above and
are easily recognizable as they will be located next to the water heater. Another may be for the toilet shut
off. The fifth 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.
DRAIN VALVES
The line drain valves have been moved to the exterior of the
y
pan supports the water tank.
The line drains will be the two brass petcocks extending from the end of the pan. The white plastic petcock
you will see is to drain the water tank.
To Empty Fresh Water Tank
Pumping the water out with the self-contained water pump may empty the fresh water tank. Simply turn on
the pump switch and open a couple of faucets until the water will no longer comes out. On all models there
is also a petcock type drain valve located in the wheel well and extended out through the tank support pan.
An additional drain plug is located on the bot
the petcock that can be seen on the bottom of the tank support pan.
Note : For winterizing purposes, only the petcock behind the tires needs to be opened to drain the tank.
