Black tank vent

[Passin Thru]

Due to tracking down a leak I found that the black water vent pipe did not extend far enough from the roof line to fit into the 360 degree vent as it was supposed to. In fact it was about three inches short. It appears it had been leaking for awhile since the area around the hole cut in the roof was rusty.

Has anybody else found this? Another example of the workmanship not matching the name brand.

The vents on our 2011 were sun damaged so I recently replaced them with the new style 360 siphon vents. While I didn’t find much water damage in that area, the metal was rusted. The original vent pipes were cut at different heights (>2”) so I don’t think the factory folks spent much time worrying about whether it was done correctly.

Yes - found the same problem on my 2013 Interstate when I replaced one of the 360-Shipon vent caps with a lower white model to clear the solar panels I was adding. I'm attaching photos of what I found and how I fixed it. I added a short extension to the vent pipe that was about a inch short of the metal roof.

Boxster - I haven’t fixed mine yet (waiting for a dry day) so your pictures and method of fixing will help. In your pictures it appears that there was a flange between the old vent and the roof line that you did not have to remove. Is that correct? I was wondering what the vent actually rested on due to the thickness there.

Yes - there is a thick "donut" ring made by Airstream from clear acrylic plastic to make a flat mounting surface next to the roof rib.

Plenty of info on vent leak I had reported in the below thread.
