Bedroom slide brings in water
Since getting this coach in March I have noticed that after bringing the slides in within a few days of rain, I will get water on the floor in the bedroom after driving the coach. My first conclusion was that there has to water on top of the slide and after bringing the slide in and driving down the road it would run off and onto the floor. After 4-1/2″ of rain on Wednesday I pulled the slide in today for a short run up into the U.P. Before pulling the slides in I climbed up on the ladder and was happy to see that there was no water on top of either one of the slides. However much to my surprise, after driving the coach about 10 miles down the road my wife confirmed that once again we had water on the floor in the bedroom. We have never had this issue with the living room slide. Only the bedroom slide. Does anyone have any idea where it is coming from and what I can do to avoid this in the future? I have no problem with leaks even in the heaviest of rains. I just can’t figure out where this water is being held.

Dean.
Has your coach ever had a delam issue, and if so has it been repaired?
I know of two owners who had a similar issue, and they may respond. It appears either on the bedroom floor or it works its way into one of the bays. Based on that I would be on the phone to Prevost Jacksonville who I believe has the most experience with leaks of that nature.

Ditto what Jon said Dean, Jax is the place to go.

Would Jon & Tom think that this issue might be more skin related than slide related.

Right now that is my opinion but keep in mind a forum on the internet is not the best place in the world to diagnose problems, especially those that are an extreme challenge when we have access to a coach.
There are so many possibilities for leaks the only real way to identify the source is to try to recreate the problem using various methods ranging from spray from a hose to pressurizing the interior and soaping the outside to look for soap bubbles.
As described the leak sounded like the same thing two of our members encountered. But feedback from others who initially thought it might be a skin related problem have revealed other potential leak areas so if I were in Dean’s shoes and I could not find the leak on my coach using some basic techniques I would be arranging for an appointment in Jacksonville. They have become the experts in the Prevost organization for this type of issue.
BTW, Tom had a leak in his coach once and pressurizing the interior using the OTR system along with spraying some soapy water he found his leak source quickly. I will let him elaborate on how where a leak starts, and where it shows often does not make sense.

Immediately after or during a rain storm, lift your bed (I would assume you have the same configuraton as I have) and look toward the bulkhead wall and see if you have water there (alot of my electronics are under my bed). If you do have a water accumulation, the problem is probably where the outside panels meet the opening for the slide, in my case it was the seal along the panel beneath the slide. Hopefully you can understand what I mean. But Prevost Jax is the place to be and John is the guy.

I don’t think Dean has OTR, but if he did, it’s the best leak detection you can find. Pressurize the coach with the OTR, you can hardly even get the door to closed, get our your soapy water bottle and you’ll find your leak.
This is the passenger side cargo light.

I don’t have OTR but Prevost Ft Worth pressurized the bus to check for roof leaks and delay. Worked as Tom described. -
I had a good portion of the bed assembly in the slide out apart today. I’ll be at Jeff’s place here in a few weeks and have him look at what I’ve found and then if need be have Prevost look at it. Thanks.

Dean,
Keep in mind that unnoticed moisture entry may initially just seem annoying but any moisture entry has the potential to do serious and very expensive damage.
Obviously if some of the wooden components like flooring, bay walls, bay floors, etc gets wet and then does not get dried out rot can begin. Wood can deteriorate very fast if the wood is not allowed to dry out.
But as bad as that can be the thing about moisture that is really seious is it allows mokd and mildew to form and spread. Remediation of mold and mildew damage is vastly more significant and serious than anything else.

Check the seals around the lock Pin cups, if they are bad the water will run in and build up in the bottom of the slide . It will then run out on the floor when the slide comes in.I helped a friend find this problem on his 2003 Liberity XLII.

Did you mean lock pin cups? They are visible when the slide is extended and exposed to rain, power washers, etc.
-
Yes thats what I mean,they leaked and filled the bottom of the slide with water.
We drilled a small hole in the bottom of slide and a couple gallons of water came out,once it stopped we sprayed water on different areas of the slide starting at the bottom and working up, no water appeared until we sprayed one of the top lock pin cups then the water poured out the bottom through the drilled hole again.
New seals installed by Prevost Jacksonville,FL solved the problem.Gary

If I were going to guess at this point I would have to guess you might very well be right. We have driven in heavy rains before with no issue of water getting in. It’s only after pulling the slides in following recent rains that we seem to have the problem. I’ll let you know what we find.
-
This is pretty basic, but if the slide itself is leaking rap your knuckles on the bottom. If it has water in it you will get a thunk instead of a tinny metalic sound.
The cups for the pins are not the only potential source of leaks which could originate at such diverse locations as the aluminum top extrusion, the glass, etc. The leak would have nothing to do with the slide seals, but could relate to the skins.

I made a rookie mistake (one of many) and didn’t park level with the curb side down lower and the slides out. The rain came and I had water on the floor underneath the salon slide. Rained numerous times afterwords with the slide out and level and no problem.
