Tank vent entend

[Stew]

Any thoughts on how to extend these vents to at least the height of the maxxair vent? By not being that high, we sometimes get the odor from the black tank.

Is your fan bi directional? If so extending the vent(s) might reduce but probably won't eliminate the odor.

If you remove the top of the cap, you'll see the end of the vent tube. Maybe glue a 90* elbow and bring the pipe back, then another 90 and then a different cap.
