AC condensate tube on 2015 25' FB Flying Cloud

[GLovedahl]

I cannot find the condensate tube on our 2015 Flying Cloud. The condensate is running off the roof. The only tube open to the outside is on the curbside, just aft of the small storage bin. Inside that bin is a white valve that releases water through that tube to the ground when turned. I have no idea where that water is coming from. The freshwater tank is empty. A condensate line wouldn't have a valve, would it?

On our 19 Bambi, the condensation tube is located next to the streetside wheel well, a short dark stubby tube. This goes up to the AC but occasionally we get a few drips inside the coach. They are known to sometimes get block with something or other.

My 2013 25FB is like crazylev's 19: forward edge of street side wheel well.

The valve and drain tube by your water heater is for draining part of the interior plumbing.

Finally found it (them) by using the sense of touch rather than vision. TWO of them up under the street-side wheel well, right where they're supposed to be. One question....I plan on using an air compressor to clear the lines....anything to watch out for? Thanks

I had the same problem on my 2013 25FC. I removed the inside cover and found the drain lines routed over the power cord. I rerouted the tube and blew it out And works fine. I do not know you could do that in the ducted systems.

Sounds like a warranty item. Take it back for diagnosis.

Be certain to tell what you discover. I have a 25FC, 2016 and might have to look into a similar issue.

I have a FC 25FB 2016 as well. My trailer came with 50 amp service and two air conditioners. The condensate tubes for the AC units run down a 1/2 clear plastic tubes that terminates just forward of the front tire on the driver's side of the trailer. I don't know if Airstream runs a second 1/2 tube in case of a later addition of a second AC unit - rare but not unheard of. The two drains that you located sounds more like the low point drain valves for the hot and cold water lines. They are made of brass and have red paint on the end of the valves. I do open these low point valves and use the compressor to blow those lines dry as a part of the winterization process. However, these low point drains are completely isolated from the AC condensation discharge tubes (which don't blow out as a part of that process). You can access the tubes by removing the filter covers from the ducted returns in your trailer - mine can with a pinch in one of the tubes that resulted in poor drainage from the unit. A blockage in the AC condensate line could cause water to come off the roof as it overflows the drip pan. I hope that helps.

Our condensate tube is streetside forward of the wheel well....it drips onto the streetside forward tire (black tube).

Our 2012 had the most of the water running off the roof, usually by the door. It turned out that the AC drain pan was cracked, which was fixed under warranty but took 3 trips before they figured that out.
