Siphon 360 vs Vacu Jet
I previously had the Vacu Jet on my black tank vent and would get a strong odor when flushing. The odor wasn't so much a sewage smell (although I imagine it stems from the sewage), but more of a potent foul knock you down smell. At any rate, I I installed the Siphon 360 with high hopes, but unfortunately have noticed no improvement.
When on the roof I could smell an odor out of both the vacujet and siphon 360, but it isn't even remotely close to the same intensity as the odor that will come out of the toilet when flushing. Maybe I have a partial clog?
