Water from Leak Collecting in a Drawer

[RichCamps]

Hello all,

I have a 2004 Itasca Horizon 40 that has developed a leak and the water collects in the top drawer under the cook top. I pulled out all the drawers to look at the floor under them and cannot see any stains or water collection. Has anyone run into this and can you help me figure out where the water is coming from? Thanks in advance.

A big thing on chasing leaks is to know where the plumbing is located and that varies with different models year, make, model and the 04 Horizon 40 foot has four different models, so getting the correct drawing requires knowing which of the four? 40 AD, 40 KD, etc.?

But it will help a great deal if you can determine what type of leak it might be. Does it seems to be an outside leak as it gets wet when it rains? Does it only get wet when the slide is out?
Or is it the other two which means does it get wet when you drain the sink or does it seem to get wet and stay wet when you are hooked to city water?

Any clues of that sort can help to narrow the search!

Thanks for the note. The slides are in and the RV is in storage and empty. It's been raining a lot here in Central Florida so I only assume it's coming from outside. I'll keep searching. Thanks

Since it is thought to be a leak from outside, some ways to tell where it comes in may help. One way to do that is to make some form of "trail" from where it may be getting in and that trail has to be permanent enough to stay after rain has stopped and you next come to the RV.
A couple ideas that might help depending on which RV and how it is laid out?

Along a horizontal surface a light dusting of something like flour will show it has been wet for a really long time after it stops getting wet.

The walls are a bit harder and if it is coming from the outside and getting into a drawer, it sounds like something that comes down to wall, possibly hits a brace or drawer support to run horizontal for long enough to get over the drawer to drop off. Taping paper towel or tissue on the braces which are suspect will give you a clue for whether they are the path, while taping tissue, etc to the wall can tell you if it is running down at that spot.

But it often takes more a really good guess or luck to spot it! About the only good thing about leaks is that it almost always runs downhill if the RV is not moving! But moving the RV and leaving it tilted a different way may make a leak show at a different spot instead of the drawer.

Just a bunch of fun!
