Mystery Water Leak

[Capt’nKarl]

2018 R-23. History. I filled the fresh water tank and trailered the boat to a launch ramp. While preparing the boat at the ramp I noticed a small amount of water on the floor boards in the cabin outside the fridge. I originally thought it was a spilled water bottle. Upon further inspection I found fresh water below the step where the shower pump is located. There was at least a gallon of water there. I cleaned that up but continue to find water leaking into that area. The bilge is dry. The water tank gauge doesn’t appear to be falling. There is good water pressure with the pump on and no cycling of the pump when all taps are closed. The air conditioner was not on when I first discovered the water present. I did notice there was no water coming out the tank vent when I filled the tank. Any suggestions?
Thanks,
Karl

If water did not come out of the vent when you filled the tank and it should have I would suspect the vent hose. Is it possible that the hose became disconnected from the vent or the tank?

Could it be the fridge condensation tray sloshing water around and spilling? Maybe the drain is plugged.

Thanks for the responses. I will need to check the vent hose when I get back on land. The fridge is dry and no more water on the floor. I’m currently using the air conditioning and watching for any water coming out of the port drain. So far I’ve not seen any but the drip was there prior to turning on the AC. Here’s more information that leads to more questions. After multiple times (>6) sopping up small amounts of water from the shower sump pump area I got the area nice and dry. Much to my surprise within 20 seconds a drop of water seeps down from the direction of the bow. I pulled out all the cushions and below them ; bone dry. The bow thruster area is bone dry but there continues to be a drip, drip, drip of water coming from somewhere. It’s confusing because the drip was happening before I turned on the AC. All responses are appreciated.

On my 2021 R27 I had a small drip from the PEX fitting under the head sink when the fresh water line was pressurized ( pump switched on, even if not running). It pretty much stopped dripping when the pump was switched off and the pressure was released by opening a faucet. I had to disassemble the fitting, lube the o-ring, and push it together again. Very cramped under that vanity, by the way. Might you have something like that going on?
