Just noticed this on a recent trip while hooked up to campground water. I'm was not using the shower and the shower floor is dry. Anyone had a similar issue? Maybe a leak inside the water hook up point? I am using a pressure regulator.

@Sneakle last week i had water seeping from under the kitchen cabinet, it turned out to be loose hose connection going into the faucet, that became a problem after nearly two years of use. I suspect you have the same problem2017 T@B 320S 2019 Jeep Cherokee - Southern Connecticut

The threaded connection between the city water port and the inside plumbing has a history of loosening up and leaking. See if you can reach it through the access panel and snug it up a bit.2015 T@B Max S (320)

Good idea. I'll check that first. I guess you mean access panel behind toilet?ScottG said:The threaded connection between the city water port and the inside plumbing has a history of loosening up and leaking. See if you can reach it through the access panel and snug it up a bit.Tab 320s Boondock

Another place to check is the water lines going to the shower. You may need to remove the corner access panel on the wall where the tv is. Check under the driver side bench seat too.-Brian in Chester, Virginia

You might have to be a bit of a contortionist to get your hand where it needs to be, but it's doable.While you are in there, there are also threaded connections between the water pump and the distribution system. You might want to check those as well.

@Sneakle, you might find my photos on this page helpful for seeing what the inside of the city water port looks like where you can tighten it by hand if lose..

I also later added an access port below that door in the wall, so I could get my arm in there easier..

Looking forward to hearing that you found the source.
PS:
One other spot to check inside the toilet wall is where the toilet supply line branches off the main cold water supply water line inside the wall from where you see it to right of the toilet. I think @ScottG had a leak there once.-Brian in Chester, Virginia

are you using a water pressure regulator between the shore/city water connection and the trailer? If not, pressure greater than 50psi could cause connections to leak, whilst they do not under the water pump. This would be the first thing to check. You can also get a water pressure gauge that connects to a hose bin to check the water pressure on both sides of a regulator to make sure it is working. I keep one in my trailer tool kit.

It takes a long skinny arm to reach down that far while practically standing on your head. I'm lucky to have a long skinny arm. It was a bit loose and I hand-tightened it.ScottG said:Sneakle said:

yes, always using a pressure regulator.
I snugged up the fitting where the outside water comes in by reaching down inside the hatch behind the toilet. We'll see. If there was ever any standing water it has dried up so hard to determine where it came from. Testing now. Didn't see any issues under sink area.Tab 320s Boondock
