On our last trip (Port Aransas, TX last week) we noticed the Carpet in the basement was wet when loading up. Immediate thought was leak in the bathroom sink as the wet area was directly under the sink plumbing. This weekend, at home, we took everything out of the basement and tried to identify the problem by running all the plumbing. No leak was spotted. There are only 2 things that were different this trip than any other...1) we added a water filter and 2) we used the outdoor shower. When checking the plumbing, we did not check it with the water filter installed. I know our filter was hard to get tight enough to prevent leaks and wondering if it could have spewed up the hose, ran down another hose and dripped in the basement without us noticing as we did not enter that side of the basement after setup until we left. The other thing that may have been possible (I guess) is when we first attempted to run the outdoor shower, there was no water coming out because the hose was kinked inside. When resolving that issue, the shower worked fine but wondering if it could have somehow leaked through a fitting due to pressure of kinked hose and got the basement wet. We spent hours yesterday thoroughly checking all plumbing and cannot find anything leaking. We checked plumbing both using city water and with the pump...nothing...no drips and no moisture on the lines. This has me pretty puzzled because if there is a leak, I want to fix it soon so it doesn't cause damage but we can't find anything. Anyone ever experience something like this? Have any suggestions for us to check?

Also, all of our connections and outside shower are in separate compartments from the basement but plumbing runs above basement.

In the past my bathroom sink faucet water inlet connections would come loose and leak. It was just a dripping leak but would get the basement carpet wet.I used to tighten it and then a few trips later it would leak again. I finally took both hot and cold loose and wrapped teflon tape around the threads. Hasn't leaked or come loose since.I would say your problem has to do with the filter issue.

We really thought it was the bathroom sink because of the location and didn't bother with hooking the filter up to check.

Do you have a black water flush? If you flushed your tank right before you left, that could be the problem, this happened to me. Good luck, KB2011 Cameo 37RESLS2012 Ford F350 PSD DRW

I have had several leaks in the hose's behind the UDC. Find and fix one then 2 leak. Fix them, all is good for a while then another starts leaking. I bought 25 stainless worm type hose clamps and replace as needed. Those POS crimp on clamp should hold given they are such a PITA to remove. I have found that when the temperature fluctuates enough it will cause some to start leaking. :M

Mine just shot craps. I found it cus water was dripping in the basement down the PEX tubes that ran up to the bath sink. Turn out there were four lines going up there. Two of them were for the vac breaker which was zip tied to the sink lines inside the storage under the sink.

UDC stands for universal docking center. On mine all the hoses, tv cable, valves are in the udc.

It is a Camco water filter with hose. It's indoor/outdoor and fit in our docking station area so we hooked it up there on the last trip. The docking station is an enclosed area on our trailer but I suppose it was possible to have spewed up the line and run down into the basement. That is the only thing I can think of because NONE of the plumbing seems to be leaking. We examined everything. Crawled up in there and followed all plumbing while it was running to it's respective location of service. No drains, no incoming lines...nothing shows to be leaking. The black tank flush was not hooked up to water (separate outlet) when the water was noticed in the basement so I really do not believe that could be the problem. Also, when we ran the tank flush after already noticing the water, we watched the lines to verify nothing was dripping anywhere. That was during our initial inspection while still at campsite. I do know that DH did not get the hose tight enough to the filter and we noticed a little water on the ground when leaving to go the store that first day. We weren't going to be gone but a few minutes so decided we'd check it out when we got back. I wish we would have looked in the basement then so I would be able to quit guessing and worrying about it but we didn't. Just tightened the hose and assumed all was well (it no longer leaked...so we the ought). The next time we got on that side of the basement was when we were getting ready to leave a few days later. None of the plumbing was wet at the time and we couldn't trace the leak. Waited till we got home to try and find it but can't find anything. It remains a mystery.

I had a leak in the basement that took a long time to identify. It turned out to be the shower valve between the back of the shower wall and the trailer wall behind it. It only leaked when the shower was in use, and it dripped down on top of the drain pipe, which cause me to change drain parts several times. :)

We ran the shower quite some time trying to verify it wasn't the problem. There was no noticeable evidence pointing that direction. I am still stumped but hoping the filter proves to be the issue so I can quit worrying about it.

We do have a black tank flush but it was used after the water was noticed. I am really not 100% sure where the water came from and I still have not hooked the water filter back up to check if that was the problem but am thinking after elimination of other plumbing that it must be. I will check that and monitor it closely when we camp next weekend as I've had too many irons in the fire since I posted this without enough hours in a day to get it all done. I really appreciate the input that I have gotten on this post.
