Water on top of front grey tank

[jeff12]

Hello I have some water on the top of my front grey tank of a Grand Design Solitude 380FL. How do I get to it and how do I determine where the water is coming from?

Hi Jeff,

Welcome to the site. Including a bit more information would help us help you. There are a lot of really smart people here.
Have opened the coroplast bottom to look? Is the water pooling anywhere specific? Have you tried using a camera to see more detail... One item I recommend to visually inspect the situation is this: amazon.com. That can help locate the source.

I had a similar situations. One turned out to be a loose fitting that was buried in that black foam. Hard to find since it was a slow leak. Another slow leak turned out to be the threads on the filter to the water pump were just a tad loose. A simple quarter turn fixed that.

Hello TravelHabit Thank you for your response. The water is pooling on top of the front grey tank not a huge amount but enough. the hot and cold water supply for the kitchen sink which is wrapped in insulation is a little wet. but I don't know if that is a direct run or if it T's off for the half bath. I will check out that camera on Amazon

In my case it was very hard to find the leak that ended up being wrapped in foam. One you eliminate other possibilities you will have to remove the insulation to inspect each fitting. My post "pex-plumbing-leak" has a video of what I finally found. Note: once the insulation was removed it leaked much faster making it more obvious.

Yes I think my problem is a fitting also. But my bigger problem is accessing it. I think I'm going to have to drop my under belly to access it.

Well I dropped the underbelly and the insulation is wet but I can't find any leak I'm stumped. But I did find that It's not the grey tank but the fresh water tank. But I also found a hydraulic fluid leak and don't know where that is coming from either. I think I'm going to have to call a mobile repair service. Oh the joys of owning an RV
