Need help with Airstream plumbing issue...

It was a starting point. I figured anyone with a similar Airstream would know what I was talking about. I'm exhausted and sick and trying to help a friend so may just ask questions if you want to help rather than criticizing my word choice. Plumbing in an Airstream is not straight forward for someone not familiar with the way Airstreams are designed which is why I'm asking in a vehicle specific forum.

Is this a generational thing? Opening with a critique of how the querent could have better phrased their question? Leaves me regretting my request for input -- every single time.

I'll figure this out on my own.

Sorry to hear of your poor health. I'm sure climbing around and under a trailer isn't where you want to be.

Unfortunately, with mechanical systems there is a nomenclature and getting beyond that for the lay person can be a steep climb. Even with totally accurate descriptions and a few pictures, it will be difficult to answer a lot of your questions. Trying to establish procedures and tactics to make the Airstream's plumbing serviceable may involve "hands on" work and experience with RV systems.

If you post on the Airstream Forums, you may get a description of the original '72's plumbing. That could help you sort out what additionally has been done with it.

Beyond that, there are two supply lines to service the hot and cold water. The drain system may have a single tank and output, as many of that era did. You observed a pipe draining when water was sent down the sink so the drain system may have been altered to drain grey water away while waste is contained. Again, hands on work with the different drains would show the functions.
