DRAIN VALVES
The hot and cold water line low point drain valves on the 22 ft, 25 ft sleep six, 27 ft,
and 28 ft. are located on exterior of the coach for easier access. If you look under the
trailer, you will see a “box” that is a few inches lower than the trailer frame. This “box”
or pan supports a water tank. The line drain valves will be the two brass pet cocks on
the bottom of the pan.
The 23 ft and 25 ft. front bed model has the low point drain valves located inside the
roadside rear exterior access door.
The 19 ft. line drain valves are located in two different places. Two are located under
the rear bed and access has been provided in the bed top under the mattress. (If you
are long and lanky, they can be reached through the exterior storage compartment.)
The other two line drain valves are located under the roadside dinette seat. Remove
the cushions to access a removable panel in the lounge top.
The 16 ft model has two drain valves that are located under the roadside dinette seat.
Remove the cushions to access a removable panel in the lounge top.
Open these low points drain valves and use the hitch jack to raise and lower the trailer
front end to drain the water out of the hot and cold water lines.
To Empty Fresh Water Tank
On the 22 ft, 23 ft, 25 ft, 27 ft, and 28 ft. models, a large valve on the fresh water tank
pan under the trailer drains the water fresh tank. The water tank drain valve on the 16
ft. and 19 ft. model is located under the roadside dinette seat; remove the cushions to
access panel. Pumping the water out with the self-contained water pump also empties
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 the 22 ft, 23 ft, 25 ft, 27 ft, and 28 ft. models, an additional 1 ¼” drain plug is
located on the bottom of the tank inside the galvanized “box”. The plug is accessible
by removing an inspection plate close to the petcock that can be seen on the bottom
of the tank support pan. There may be a little Styrofoam insulation covering the plug
that should be carefully removed and replaced.
Note: For winterizing purposes, only the large tank drain valve needs to be opened to
drain the fresh water tank.
Water Heater Draining
All models have a drain plug or petcock on the water heater. Access is from the exte-
rior. The plug or valve is usually located in the lower left corner, viewed as you face the
exterior of the water heater.
TOILET SHUTOFF VALVE
Your Airstream has one other water shutoff valve. It is located behind the toilet and
used to shut water off to the toilet in an emergency or service situation.
