Water Leak from mystery hose under camper.

[wwt]

I have a 2014 Jay Flight 22FB and on our first outing we over filled the gray tank. Oops.
The tub and bath sink had water at the top of the drains. The sink didn't make sense because it is higher than the tub.
Anyways, I went out to let some gray water out and I noticed water dripping from the right rear corner of the trailer. The black tank is at the rear and the gray tank is in front of the black. The water was dripping from a location where a white hose comes out of the plastic under wrap and goes into the black tank. There is some spray foam where the hose comes through the wrap and the water was dripping from the foam.
So, what is this hose and why would gray water be dripping from that area? Could the hose be the black tank flush that has a hookup on the rear of the trailer?

It could be that the grey water tank isn't sealed and some water has run out from where the pipe enters the tank. That water could travel across the tank and run across the fabric or plastic under the belly of the trailer to a place where it can run out.

The only tank that would have a over-flow hose would be the FRESH water tank. The GRAY and BLACK water tanks should always be captured and not draining under your trailer onto the ground.

I have a StarCraft 235fb, it is almost identical to your Jayco 22fb, except it has the shower on the curb side of the bathroom. I think Clutch's explanation here is probably on the mark. Especially since it seems that the water is dripping from the foam. My guess is that the tank has backed up your drain system where there isn't a tight seal, and is just leaking onto your belly cover, and then finding the way out via the lowest point.

I'd pull the coroplast down, dry it out, and then you have a couple of choices.
If you want to find out exactly where the leak is coming from, refill your gray tank to overflowing and look for the leaking junction while the belly cover is off.

Or, just assume that you will not have a problem if you never overfill the gray tank again.

Thanks for the replies. After thinking about this more and reading Clutch's response I think there could be a small leak in either the sink drain line or the tub drain and probably where they go into the gray tank.
I'll take Dewey's advice and try not to overfill the tank again.

When I picked my 334RBTS Eagle from the dealer, had two big issues once we got on the highway, one water was coming out of the underbelly in the rear, second was the damn thing was swaying all over the highway. Found the fresh tank was full causing the trailer to sway really bad, then the overflow lines for the fresh tank were never stuck though the underbelly causing the insulation to soak and leak everywhere. I would find the fresh tank and check where they put your over flow hoses (if there's water in your tank)

Well, when I filled the fresh tank(s) I got water pouring out of two hoses on the left of the camper just forward of the tanks. They flowed water for about 2 minutes then stopped. So, the fresh tanks were completely full. The location of the drips when the gray tank was full was on the right side of the camper. I'm guessing this was where the gray tank fill line was at.
I have since poked a small hole in the under wrap beside the foam sealer and no water came out so I don't think it was holding any water. I'll just be careful to not over fill the gray tank again.

I had the same thing happen to me. When I ordered the TT, they told me all of them came with the underbelly cover. When I went to pick up my new TT, it had none. So I made them order one and when it came in they installed it. First time I filled, water started pouring from the coroplast. They had simply put on the underbelly and didn't daylight the overflow tubes, so they poured water right onto the underbelly. I fixed it myself, thinking that the dealer had already screwed up twice (not giving me what I initially ordered and then installing it incorrectly).
