Filling H20 Tank via Hooked-up Hose

[Mike76251]

Hello again,
I have a 1972 International '31 rear bath with three valves under the sink.
Tow of them seem to be for draining the water lines and I am not sure what the third does.

Is there any way to fill the darn water tank in this thing other than flipping the outside fill-door?

The owner's manual does not indicate a way.
Thank in advance,
Mike

No, check valve in water pump will prevent backflow to water tank.

My MH does have an electrical valve that is actuated from a switch on the contro panel that allows the Potable water tank to be filled from the water connection.

As for third valve, maybe cutoff to hotwater heater

Mike.

The purpose of those three valves are as follows.

One drains the "cold" water line. The second drains the "hot" water line. The third, drains the water tank.

Suggest you call Helen Davis at 937-4928885 and obtain a "service manual" for a 1973 trailer. For all intents and purposes, your 72 is the same as a 73.

You will find many many great areas of information as to how to, etc, especially if you want to do the repairs yourself.

Your question about the three valves is answered in that book.
There are two more valves in the back end of the trailer called the one stop center. They also help drain the hot and cold water lines.

These valves are "NOT" to be confused as the proper way to "winterize" the trailer. They assist, that is true, but far more must be done for a proper winterizing of the trailer.

Andy and Smily.......thanks!!
As for a service manual, thanks for the tip on the '73 model.....I didn't know that.
I don't know much about winterizing my 72 because I have never done it. Not in 11 years of ownership.
I have all the lines covered with sooo much insulation and replaced some of the copper with thick-walled stainless tubing so it don't freeze.-I should say it don't break-

Airstream Service Manuals started with the 1973 model year.

Fortunately, most of the 70, 71, 72, 73, 74, 75 76, 77, 78 trailers had identical companents or systems. The newer years of course had upgrades and additional compnents.

Therefore using a 1973 Service manual for a 70, 71, 72 is for the most part ok.

CAUTION.

The Service manuals were written by a publishing company, not Airstream. Therefore there are some mistakes in those manuals.Usually, they are obvious.

Also, most of the part numbers especially in the 1973 manual, are obsolete.

I believe the third vavle drains the on board water suppy

Is it worth getting the manual for the "73 then? We do have the original owner's manual for our AS. Are there any books on where to place the grey white black water tanks? except by the axles? And what sizes are best for long term use? I definately am feeling overwhelmed right now, but John is happily drawing the existing wiring system now. silver suz

Get the "service manual." Call Helen Davis at 937-4928885.

Once you have the manual, you will answer some of your questions, but then more questions will come to mind.

The location and capacity of a gray tank is dictated by where you must locate the tank.

To properly determine the size and location of a gray tank, you must remove the underbelly, and see what area is available, it's advantages and disadvantages.

Andy,

You are a walking, talking Airstream encyclopedia.

Amazing......
