We are about to pull out here and I was hooking up the water hose to the Airstream. I turned on the water so we could take our baths...But here at the rear underneath is this little pipe-that when I turn on the water it automaticly starts running as you can see in the photo. So we opened up the compartment right above and took another picture of these two valves. I don't recall ever turning either one of these in the past, and was wondering if you guys know where that water below is coming from. It makes the sound of running water as it's coming out --please help this morning.

Thats a water drain line for winterizing the Airstream. Turn the red handles (one at a time) clockwise and see if that stops the water from coming out.

Looks like you have the drain valve open. Try shutting the valves one at a time to see if it makes a difference. You could have a bad seal in the drain valve as well. Is there a pipe going thru the floor near one of the valves inside? If so, follow the pipe back to see where it goes.

We started to turn the red handles a few minutes ago and hesitated before we did it and got on here instead...in a few minutes we will go back there and turn the red handles clockwise (shut) to see if one of them was loose. This is a new one for us- as it has never happened before. So I will report back in a minute and let you know Thanks....

Ok first of all there are TWO of those pipes (one on either side of the big outlet) it's just not in the picture. So we opened the valve first and water increased out of the one that is not in the picture. Turned it off. Then opened the other and water came out the same pipe again. THEN we tightened the valves clockwise pretty darn tight and it still persist. I stuck my head in there and looked down and it is really hard to tell where that pipe is going.

Odd! One tube should be the cold water drain and one tube should be the hot water side. Should not use the same for both. Any more red handles?

no there are just those two along with that up and down shut off thing.The one you see is the one that is constant. and the other seems to be doing all the work from the two red valve handles...after we take our baths and it dries out back there I will return with more photos and closer inspections. I will persist and prevail and will get to the blttom- and or end - of this!

There is a high pressure "pop off" valve, that over time, goes bad.

That allows water to flow out one of those clear plastic tubes.

The valve is not large, and it has a number on the top of it that says "111". I will post a photo of it later today.

Replacing that valve stops the problem.

The only other cause would be for one of the drain valves not completely shutting off, but not likely.

You know Andy - I've purchased my Airstream from Colonial out in New Jersey - but once I tow her X-Country back to my San Diego domicile - you know darn well were "MY RIG" will be coming for service!

You are always there to help everyone!!!

Andy saves the day! I will be looking for your pictures or diagrams when they happen...thanks Andy

Photo of the Airstream high pressure "pop off" valve.

If you have a pressure regulating valve,why would they install a pressure relief valve ? I think I would throw away the relief valve and install a good pressure gauge there.Dave

Water pressure regulators have been known to fail.

The "pop off" then becomes a "safety" device.

OK I saw the picture- should I go and look to see anotherone like it connected to my plumbing in there? Or where is it installed? And what else can you tell me to do to look and find it. Bill and if you have that piece about how much does it cost? Or do I just push it back into place?
