2024 Europa 32KD Kitchen Sink Drain

[MVD]

We started noticing some moisture on the floor the past couple of days when we extended the D/S slide. It was really wet yesterday when we were using the kitchen sink, so I suspected something was loose at the faucet or the drain. I started looking to see where it was coming from and it is leaking at the drain so we stopped using the kitchen sink.
Unfortunately the leak is under the slide, and I can barely get my hand in there, let alone do anything once my hand is in there and is difficult to even get photos.
The leak is where the black drain pipe, is connected to what looks like a flexible gray drain hose? It looks like there is a white slip joint nut that connects the flexible hose to the black drain pipe. The leak is definitely at this connection.
Looks like maybe the flexible hose is not inserted properly into the white joint nut?
I am not familiar with this type of drain connection, but it looks similar to the joint nut or trap adapter?
Is it a compression fitting or??
It seems impossible to get enough access through the floor under the cabinet to do any further assessment or repair. I don’t see an access panel under the theater seat. Is there another way to access this connection? I have reached out to Bradley at Dynamax but am hoping I can fix this asap myself so we can use the kitchen sink. Does anyone have any suggestions on this?
Thank you
Mark

I have the exact same problem. My hands are too big to repair from there. Were you able to find another access point. Please let me know as I’m a long way from a dealer. Thank you

I was not successful reconnecting the fitting, so Dynamax recommended we take the Coach to Camping World San Diego for warranty repair.
They were able to get the fitting reconnected but found a slit in the flexible drain hose under the slide. We are currently waiting on the new drain hose to arrive so they can complete the repair. The work order indicates they removed the fascia on the slide out for access to the drain hose.
We had the coach out for a few days over Christmas, but were unable to utilize the sink and/or test the repair to the fitting.
I will post results once the repair is completed.
So far () the service department at Camping World San Diego has been good to work with.

If the leak is at the rear where the flex line meets the main ABS drain line then a slip joint wrench can be used to tighten the slip joint nut. Most hardware/box stores and plumbing supply have these. There are several different types so you should be able to choose one that will work for you. I have also many times used channel-locks to tighten up the slip joint nuts (correct size channel locks) but the right tool for the job is always better. If the leak is at the front of the drain assembly where it makes the transition back to ABS on the sink side then you will need to drain the p-trap and take one side off via the trap nut. Then remove the mounting screws from the steel drain line mount and clamp/strap. At that point you should be able pull the flex line up and out to tighten up the flex slip joint nut. Then just reassemble. These slip joint fittings are the same as what you find under your kitchen or lav sinks and use compression to make the connection. The uni-loop flex line is a 48". Hope this helps.
