Ceiling leak

[majfrizz]

Have a new Bus 45OPP for two months. Over that time have had rain on numerous occasions, no leaks at all. Tonight after just a small drizzle, about 30 minutes later saw a drop on kitchen ceiling on the recessed ceiling tray between the front air vent and the mid AC. Picture of drip location and a large puddle on floor. Unable to get on roof tonight. Any ideas?

Were you running the ACs by chance? It could be condensation that overflowed into the ceiling from an AC if the condensation pump isn't working.

I thought that also. They were turned off about 1 hour prior, plus I have the water puddle st the back of the RV where the drain tubes are.

I would not fully discount the condensation problem. A puddle at the rear doesn't mean all three units are draining condensation properly. And being shut off for an hour - the condensation may have taken awhile to get through the ceiling.

First thing to do is check the duck bills at the end of the drain lines (normally in the right rear of the coach). They can stick and allow water to back up. If you still have problems, then you start looking at things to do on the roof - take the covers off the A/C units, check the condensate pumps, blow the crud out of the drain lines...

Just had the same problem on my 2018 opp bus. Went to Red Bay had a bubble test done with no success. Finally a Tiffin employee told me he had the issue on another 2018 OPP. The solution is over the Coach door. There is a small gap that in a hard rain the rain trough fills up and allows excess to enter the and travel just like yours is doing. Caulk this area and pull out door awning to check. This is a small gap but water can get in. I will bet this is your issue.

I appreciate everyone's response. My bet is the condensation lines, and it is just now seeping thru to that point. I will have to check when I get back to the coach tonight if the weather works with me. Been working at an RV rally all day weighing coaches in the wind.

Again, THANKS

Is this bus new to you? From the looks of your first picture, that wood trim looks like it’s been wet before from the fading on the corner or it could just be the way the picture came out.
