Question Only leaks in the morning?

My wife and I are new owners of a 2016 Flying Cloud 20FB. We took it out last weekend and had a water leak that really would only show itself in the morning. It was a slow leak and water was showing under the bathroom cabinet.

The weird part is this. We had a full hookup and good water pressure, I did not turn on the water fully, because I could tell it would have been too high if I did.

We left the trailer for 2 days and slept in it each night with the water hooked up and did not ever come home to a flood. In fact it was dry. The leak seems to have only been fresh water and only appeared when the sink or toilet was used. I cannot understand how a leak of fresh water could appear only when the toilet or faucet is on. I have checked around the toilet and around the water feed to the sink and the P-trap around the sink and cannot find anything wet.

It seems to me that it would be paradoxical to have a fresh water leak only in the wall or cabinet that appears when water is drawn, but no other time and if the trailer is left alone then there is no leak at all. Just doesn't make sense to me. I am at the point of taking apart the bathroom cabinet or worse taking it to the dealership for service and big $.

Any help or suggestions before I make a mistake are appreciated.

First off, welcome to AirForums!

Could it be a faucet washer is "old" or a mesh filter has debris blocking it? Water could be running down a pipe under the cabinet...

Does it also leak during the day if you use the toilet or sink? Or just first thing in the morning? Has it leaked at other campgrounds or just this one?

One thing you should do (instead of guessing) is get a water pressure regulator with a gauge or without to hook-up at the faucet of the campground next time...peace of mind. We use the one w/o the gauge (less out of pocket if you forget it at a campground!) and then have a permanent gauge installed inside our trailer we added when we re-plumbed the whole thing during our restoration.

Thanks for the reply. I do have a pressure regulator with a gauge, but accidentally left it at home. We initially thought it was from the shower, but tried deductive reasoning to try and figure when it first appears everyday.

Showering did not seem to matter. I did search the AirForums site for answers to my problem and we did have the heat pump on over night, which I saw one person suggest it was from roof runoff. If it was that I don't see how it could be where it was without some sign of it in the wall.

The problem seems to be first thing in the morning though. The trailer was not 100% level and the 1 or 2 degree angle would have made the water run toward the hall which is where it was seen. It is possible that moving around in the morning was enough to make the water move out from under the cabinet where it was collecting.
