On our H320, there is a Vetus ventilation outlet installed. The unit is corroding, thus leaving brown stripes on the hull. Ouch

Do you have the same on your boats?
Does anyone know the correct part no. from Vetus or did you change for another solution?

well.....let's assume it is corrosion TongueSmile

Have you checked the screws? The ventilation is the same we have on our boat and it's not corroding at all. Maybe only the screws are corroding?

You can easily remove the filter of the outlet; just unscrew the two small screws. I opened it first time some six years ago, and it was quite full of used paper. Since then I have controlled it every spring. It takes only few minutes.

P.S. I agree with Peter-Blake

Indeed the two small screws have changed color - from silver to corrosion.

I had the same issue.  This turned out to be due to the fitting being blocked.  I cleaned it out and no more stains.

I removed the mesh screen some years ago. Two or three times a year I put a hose to the exposed pipe to flush the tank and much paper etc always comes out through the sea cock. Also, from time to time when the dinghy pump is handy, I pump air through the exposed pipe which bubbles out through the sea cock. These measures help to keep the tank outlet from blocking.

Hi!
my first post here... ;-)
On our H320 the ventilation seemed blocked from time to time. Tank fllled up, although seacock was open and not blocked. I opened the ventilation a few weeks ago and found some sort of filtermaterial inside, which was in bits and pieces blocking the inlet. Does anyone know if this filter stuff is necessary and how I can replace it? Vetus does not know anything about that filter and it does not seem to be documented anywhere. By the way that thing is called - in German - "Enlüftungsnippel" (true!) and costs about 16€ .
Is it allowed to send supplier links here?

Chris,

 You don’t have to replace the “filtermaterial”. Take a look to my earlier post 4th April; you will understand why there isn’t any documentation about it. So, just clean the "Enlüftungsnippel”.
