Unexplained water on the floor

I have a 2003 Dutch Star, model 4007. We have an unexplained wet area close to the sink storage door after extending the slide. This has only happened 4 to 5 times since we purchased the coach 3 years ago. The sink water lines and drains are dry. Water heater also in that area sitting on the "slide floor" is dry. All of the slide floor is dry. i had the coach washed at Blue Beacon a couple of days before our current trip.....It has to be water getting under a seal on the bottm of the slide, right? Just wondering if anyone has a similiar issue. Thanks David

I don't know if this will apply to you, but... occasionally when we travel we will have condensation from the refrigerator that will leak out on the floor. It would run from original location so sometimes it was hard to track. A towel in front of the refrigerator as we travel solved our problem.

Had a similar leak on mine. Turned out, after a lot of searching, it was a leaking water line fitting. It just finally got to the point where it was constant and visible.

Better to fix the cause than treat the symptom. When we looked at our current coach, I found a soft spot in the floor. Condensate had gotten on and under the tile destroying the OSB floor. Required removal of all the tile, the cabinets and replacement of the subfloor. Camping World fixed the floor issue but did a poor job on fixing the original cause. I replumbed the drain system and now no problem.

Another possible source: water expands when heated, if all your water faucets are tightly closed and water in your hot water heater tank is cold, and then it gets heated it expands and unless you have a water expansion tank the pressure builds and eventually the weakest point starts to leak. In my RV this the over-pressure leak was under the kitchen sink. I put in a Surflow expansion tank to solve. The other way to solve without an expansion tank is to leave a hot water tap open to a super slow drip.

There should be an air space in the top of the water heater to compensate for the expansion. Over time the space gets filled with water. The owners manual should explain what to do about it.

It happen to me a few times. It was a the flush valve under the sink. When I was using the revervoir rinse when dumping, water would go up through the valve.

I replaced the valve and problem was solve.

Not to hijack this thread but quick note:
There is no inside condensation drain in the bottom of my double door Norcold. My solutions were:
1. Stop condensation.
2. Put towel inside Norcold on bottom.
3. Put towel outside at bottom where the water collects.
I chose door number three. I did notice while traveling out west that it only rarely happened. I suppose moving to a dryer climate would also be a solution. If anyone has a better solution PM me so this thread does not get off track... Thanks

Found it! I should have started taking panels off a long time ago, but it wasn't a consistant leak so i thought I had a slide seal leak. As I said, the kitchen sink was on the slide and the leak was in the connecting flexible hose that allowed the slide movement. Newmar's sending me the replacement hose for $10 bucks. Thanks to everyone for their input....all good idea's and made me think. Thanks! David
