Kitchen Sink "flex line" broke off at top of gray tank...

[The Gritz Carlton]

For those of you who know us...April and I are doing well in PCB. Sold home it ATL on April 5th and now full time retired here. Not traveling much yet due to The China Virus. Also haven't been on the Forum much lately as there is just too much playing to catch up on. Golf carting everywhere, avoiding hurricanes and still cooking at home 100%. This place is swamped with people from all over the country totally oblivious to this virus. My current issue: As many have experienced, the "hard pipe" on top of the gray tank that connects the kitchen drain via a flex line to the bottom of the sink broke off just at the floor line where it attaches to the top of the gray tank. I was thinking of using a super duper gorilla type clear glue and just stick it back together but I only have one shot doing it that way. Anyone have any advise on this repair or how the plumbing schematic hooks to the top of the tank? Is the fitting on the tank itself replaceable from the inside? It's near impossible just to get to this area...much less, figure out how they put it together. I also need to work the slide in and out and find out what shifted and caused this.

Personally, I'd get some plastic epoxy and put it on with that. Bonds better than generic glues to plastic.

I'm also a big fan of epoxy...
Lots of it!

Though about doing just that...then just build up around the base with more and move out of the way what is causing it.

Good luck!
We'd like to see some pictures of this repair...

Same issue here on my 29h. I went to Home Depot, got a fernco coupling, installed it three seasons ago and been working since.
It also allows a little flexing when operating the slide.

It seems I have this same issue now on my 2016 Miramar 34.1. When I run the kitchen sink the grey tank leaks from the top. I assume this is where the drain lines connect into the grey tank, but I can't see them from the outside looking into the grey tank area (see photo, grey tank is above the fresh water tank).

How are you all accessing the grey tank where the drain line goes into it? My grey tank is under my bathroom sink and I have tried to figure out how to get the bathroom sink/cabinet out and it doesn't look too easy (unlike the sinks in my house). I have taken measurements and the grey tank is directly under my bathroom sink.

I know the kitchen sink drain line runs under it because I can access a panel next to the sink and can see it running under it (see photo, the kitchen sink drain is under the heater flex hose).

Before I even try and remove the sink/cabinet I want to make sure this would even work first. If there isn't access to the top of the grey tank from here then I don't want to waste my time.

These are the parts I bought. Remove assembly just at the sink tailpiece. Saw off the blob that goes into the top of the holding tank. Once all my new parts were put together, I just pushed the clear hose into the top opening of holding tank...no issues since and no odors.

Appreciate the ingenuity as well as your personal time on this project "Gritz". As you know I was going to go this route with my issue and ended up being able to access my broken pipe and go about it different. Just figured I would share in the event someone is able to gain access as I did.

My coach is a 2016 Miramar 34.2. My kitchen sink drain line broke flush with the gray tank. After some measuring I was hopeful that the drain line was located under the bathroom sink. Thankfully it was and I ended up fixing my problem with 1 1/2" ABS.

1) I removed the bottom panel (kick plate) on the front bottom of the sink cabinet (1) by literally pushing it in. It is stapled from the inside. Then I pried up the bottom panel (2) in the cabinet.
2) I used a hack saw blade to cut the pipe and was able to leave just enough of the pipe to be able to glue on a coupling to it.
3) I used a 2 1/2" hole saw and centered it over the smaller hole where the pipe broke off.
4) I bought a gray tank grommet and pushed it into the new hole. Place a 2-3 inch pipe adjustable clamp over the grommet now before inserting new pipe into grommet.
5) I measured and glued together a straight pipe to go into grommet, 90 degree elbow, and coupling. Then inserted the straight pipe into grommet and glued coupling to existing drain pipe.
6) Ran water and checked for leaks. Then stapled bottom front panel back on and just set the bottom panel inside the cabinet without stapling so I can easily access for next time.

It worked out really good for me. I actually almost replaced the other two pipes this same way while I was in there, but decided against it.
