Gray water tank vent behind converter

[BrucePerens]

There is a gray water tank vent behind the converter. This is connected to the shower drain. There is in addition a vent grate on the outside of the trailer. I don't know if it's directly venting the gray water or if it's just venting the space under the shower.

The shower vent fan and the converter fan exhaust into this area. I don't know where the air outlet is. I hope it's not just the area around the gray water pipe exit, which I've just sealed.

There was some dirt on the vent, as if it had overflowed at one time.

This vent might let gray water odors into the trailer. I'd plumb it out the side wall if the grate isn't connected to the gray water system.
