Is your convienece center located behind those cabinets? It could be a ways away but water could be traveling along the floor to get there. If so, you have a mass of connections back there that could be loose. Another choice would be a water heater connection if it's back there.

We checked from inside the storage- took the white pretector off to look from that side. Only happens when hooked up to rv park water. Just happened for first time when the park installed backflow protectors to the water hookups.

Is the carpet wet under that window in the slide? We had several incidents where water was getting in around the outer flange seal of the window frame, coming down inside the wall, and then migrating under the wall to the carpet. This was of course from rain. Water could be coming in and flowing to the area you circled from a leak at the window. I have sealed all of ours with silicone caulk and have no more leaks.

If the carpet below the window is dry, then possibly the slide top or side seals are leaking, allowing water to enter and getting to the carpet you circled.

There was no rain- dry sunny weather. It totally baffled us. Going out this week- will see when water is hooked up- the only thing that shows the leak.

I'm no expert on this but it sounds to me if it happened for the first time when hooked up to city/park water with a backflow valve on it that the backflow may have put enough pressure on one of the connections behind the convenient center or close to it and pushed or weakened the connection between the line and the fitting. This is just my guess! Let us know what you find when you go out this week.

Had a similar issue. Found that a mouse/rat/squirrel had been in the area behind the control panel and had chewed a small hole in one of the water pipes. It started as a damp spot and as out dog water dish sits there we were blaming the dogs being sloppy, as it got worse finally over 4 days tracked to to a gnawed water pipe. Mine is the front living room and there is a desk in the area your china cabinet is. Pulled out a desk drawer and found evidence of a long time resident being there and also found quite a bit of damage to wiring etc. Repaired all found the entrance point and hopefully stopped the problem. Just waiting for cooler weather to see if my friend returns. I did leave some rat poison in the cabinet just in case.

I found that the shower door area where the frame is screwed to the shower itself wasn't caulkd well and the interior of the frame where it meets the shower stall was not called at all... I caulked these and voila, no leak! Piss poor work of you ask me!

You did say what rig you have but it looks just like mine. Check out this thread. My valve is located between shower and pantry. Look in cabinet above pantry and remove panel, then close pocket door, you should see the valve.http://www.montanaowners.com/forums/...ht=anti+siphon

Looks similar to mine. I agree with above. Get into the basement and open up the area behind the convenience center and water heater area. Lots of water plumbing in that area. See if the back panel of that lower cabinet can be easily removed for even more access.

I can see that your shower is on the right side of the door, so the leak is probably not from the shower if the other side of the floor is not wet.

Can't really see any reason adding backflow preventors would do any thing to cause a leak. That should not increase supply pressure.
