Leak

[Alaska1966]

We have a leak from this area on our Airstream. We looked through our manual and can't figure out what it is. Plus looking online here to see if there are people with pictures that look the same.
So we figure someone added it at one point. Any ideas out there?

Is the leak from the sewage drain or the belly pan? Use your olifactory detector to see if it stinks. To state what you probably already know if it shinks it's @#$%. If it doesn't it's probaably grey water or fresh water and there is a leak in the plumbing. Does it only leak when hooked up to city water? After using the sinks, or shower. This should help pin it down. Finally get hold of a service (not owners) manual with a diagram of the layout of the plumbing. It could also be a leaky low point drain valve.

Thanks. It doesn't leak when we are hooked up to city. Only when we run the sink. Does that picture look like something someone rigged at one time? I haven't seen any pictures with someone having that area drop down like that?

I took a 2nd look at your photo. I assume you are talking about the black thingy hanging down. Maybe PO put this in to access plumbing to get at the original leak but it is leaking again. I'm sure someone out there who knows your model better than I can provide a more smarter answer to your query.

If it leaks only when you run the sink then my guess is there is a leaking joint in the grey water drain line. Assuming your coach drains both black and grey water out the sewer connection, I would guess the joint where the grey water and black water drains join is the most likely culprit.

Interesting. I guess I will be doing some research to get my husband going on a new project. HIM.
Thank you.
