strange thing happened on our maiden voyage

[Cath4996]

We just completed a 10 day trip in Northern Ontario. We have a 2019 2108DS New unit never used before and everything off without a problem except one thing. One morning when we were moving we extended the jack to hook up to the truck and some grey water was leaking out the back under the bumper. This never happened again. The tank was near full however I wanted to know if there is an overflow or vent that may have overflowed or if it is a bigger problem? Anyone have any ideas? Thanks

Are you sure it wasn't just run off from the roof?

I've never had my tanks very full because I dump before each tow, or soon thereafter, and have never stayed longer than two nights.

I’m not sure how much gray water you saw. Was it a lot?

It could be nothing or something bigger. Is the sewer hose stored in the bumper? Could it have been from there?

I doubt there is an overflow on top of the tank, but there is a vent pipe that goes to the roof. If the vent pipe is not properly attached to the tank then that could leak but you’d want to have this checked out ASAP.

Normally an over full gray tank backs up into the shower (!) - who said RVing wasn’t fun, eh?

One way to do that on a DIY basis would be similar to what they do to check new construction plumbing. Once the system is basically empty, so that everything is clean (assuming you're not where you can dump dirty water), just fill it up until it does have a level inside the shower. Then just let it sit a while and see if the level drops or if you again notice water leaking outside.

Given RV dealers may be scheduling over a month out, that would be easier and faster.

(If you are where you can dump you could just fill the tank the rest of the way when it is near full, and save some water.)

In my rig, I've overflowed the fresh water tank before. But when the grey water tanks get full, it just backs up into the sinks and the shower. Likewise the black water tank, but that backs up into the toilet.
