Anyone tried the 'Xtreme Vent'?

[Eckhart]

We're thinking of replacing the little plastic roof waste vent on our 2007 Safari 25 with an Xtreme Vent that rotates and uses the venturi effect to keep the waste tanks aired out.

Has anyone tried one of these products?

Thanks.

I wonder about these things. Putting a negative pressure on the gray tanks will tend to purge the traps and purged traps will allow tank smell into the trailer. Putting a negative pressure on the black tank might also purge a trap if you have a sink that drains into it else it just tries to suck the layer of water you should have in the toilet through the toilet valve.

Fortunately, the chemical you need to keep your tanks in good shape is cheap and readily available. Dihydrogen monoxide (DHMO) is considered extremely dangerous by some but you have plenty with you (or should have because it helps your Airstream stability), and, as a universal solvent, will keep crud from building up in the tank if you apply enough to keep the waste covered.

Those venturi things do make good wind vanes, though.

The vents use a natural stack effect to do their job. RV parts are like fishing lures -- doesn't matter how much they catch fish as long as they catch you. Is this a cure for a non-problem?

No problem with evacuation traps ... not enough vacuum, even at highway speeds.

We notice that fewer odors escape when flushing the toilet in various wind conditions or with fans running. Occasionally though, when dumping with a wind blowing, some gasses may be pulled up from the sewer.

All in all, I think the vent is worth the investment.
