Possible Grey Tank Overflow or Leak

[orental]

Hello, RVers!

I have a 2023 Jayco Jay Flight 265RLS (purchased new in 2024). We’re currently camping and working remotely in Texas.

Tonight, after doing the dishes in the kitchen sink, I found some water on the bathroom floor near an interior wall, next to the shower. However, after checking, it doesn’t appear to be coming from the shower.

I went outside to investigate, emptied the grey tank (I hadn’t realized it was full), and noticed water steadily dripping from underneath the trailer. The underbelly is enclosed, so I can’t see exactly where it’s coming from, but my guess is the grey water tank. The water looked slightly soapy as well. The dripping stopped shortly after I finished emptying the tank.

Now I’m concerned—could there be a leak, or was it simply due to the grey tank being too full? Or perhaps both?

Any insights would be greatly appreciated!

Thanks,
Oren

Definately an issue. Have you pulled the small panel off below the shower door to see if it is dry there? Lay a few pieces of paper towel seperated on the floor and fill the tank. See where the water is coming from to get you started. It sounds like a pipe fitting was not tightened, of something was not glued. This may be hard to find. You should report it to a dealer to get it documented and fixed under warranty if any left. Even if they don’t fix it then, at least it is reported.

It's probably because your grey tank was full and the water almost came up into shower and there's a bad/loose connection in the shower drain causing the dripping and water on floor near the shower. As mentioned remove that panel in front of shower, run the shower and take a look. Hopefully it only leaks when the tank is full causing the water to back fill the drain pipe and can be left as is. Of course having it fixed it under warranty would be great because it's probably not an easy fix depending where it's leaking from because of the tight space and the coroplast on the bottom.

Thanks, Kevin! I appreciate the advice. We're still under warranty so I've contacted the dealer.

This was helpful, thank you!

I found all the fittings under my shower were loose. Right after bringing it home and before using the camper, I opened up all the access panels to check fittings and connections. This included the under shower access panel. There I found loose shower drain fittings. Also, the screw on water feeds, on the back side of the outdoor shower (found in an access space) were loose. Also, the drain fittings under the kitchen sink were loose. I think all these points are worth checking every few trips. Obviously, they can loosen up over time with travel.

Look around in your lockers and see if you have a tank vent running up inside. Its not one of those vents that would go up to the roof. Its a black round cap looking thing in the grey tank lines and off the loops, even the sink pee traps.

Once it's full and rising your fitting and connections are not really designed to retain water like that. I would start looking at your monitor panel and empty at 3/4 full.

"Ideally," the grey water should back up into your drains, into the tub, and possibly into the sinks when the grey tank is full...BUT NOT LEAK. The most likely cause is, as already suggested, a loose or damaged connection between the tub and the grey tank.

Loose is not all that unusual. Pounding down the road, things vibrate loose. And J-traps and tub drains are not typically "tool tight"...just hand tightened. For years, I had trouble with the J-trap under a kitchen sink loosening from 11 miles of washboarded gravel road going to our favorite campsite. I gave up and used a giant pair of Channelocks to snug up the "nuts" on the J-trap. That's kind of a ham-fisted approach, so I invested in a "strap wrench" to tighten these nuts without risking breaking them with a metal tool.

So, if you're lucky, things are just loose, and that's the most likely problem. If the connection between the tub and grey tank is broken somehow, the repair will be far more difficult in that tight space, but chances are that it can be done. With a 2023 rig, I'm thinking warranty is out of the question.

PS. If this fix proves to be too difficult, it's very likely that there will be a mobile RV repair operation near you. Up against bringing it to a dealer or shop and letting it sit, mobile RV repair will get you up and going more quickly. And when you figure in the cost per mile for a round trip to a dealer with the rig and the second round trip for going home and back, the mobile RV repair might be more cost effective. Bear in mind that the IRS allows about $.67/mile for mileage...not because they're generous, but because it costs that much to drive a car. Towing your rig will be well over $1.00/mile. One round trip with the trailer and one round trip without. It adds up.
