black tank roof
What is your choice for a roof vent. I tried a tornedo. It only lasted a year.

I'm quite happy to be gullible. Without that vent your black tank would empty like an upside down soda bottle when you pulled the handle.
The Cyclone is an add on gizmo that is advertised to suck air from the tank which is impossible. All tanks need to be vented but they don't need (or benefit from) the Cyclone.
