Toilet smell while driving

[D Lindy]

DW used the toilet while driving down the road and mentioned about a bad sewer smell while flushing. Sort of feel this is normal with wind blowing down the vent pipe while driving down the road. Open the flush valve and wind will rush in. Has anyone tried the "Cyclone Vent Cover" and will it really stop the back flow of air down the vent pipe while driving?

My friend had the same problem. He said the "Cyclone Vent Cover" works.

Don't need a fancy Cyclone. Just use a $3 plastic 'T' from Home Depot's bathroom section. Remove the original dome, stick the 'T' on top of the pipe, a little caulking, done. $6 total.

We installed Cyclone's on ours work great, they also turn with the wind when parked. Jim

Were you driving with a roof vent partially open or a window open? The low pressure will cause the fumes to be sucked out of the tank when the flush valve is opened. If you close windows and vents, then the odor will stay where it belongs. Regardless of vent cover type, Cyclone vent cover, a rear facing elbow or just the standard round vent cover, if a 14" square roof vent is open, it will draw far more air than a Cyclone vent just by eyeballing the relative sizes of each.

If someone makes a stink, open the roof vent after flushing!

First, to answer your question, yes the Cyclone does work and works well. We had an odor coming from our grey tank and once the cyclone was installed it went away. One suggestion would be to fill the toilet bowl with more water before flushing to keep odors from escaping. The less time the flap is open the better!

I never drive with a window or vent open and all my coaches smelled if the toilet was flushed. Most all my customers complained about the same thing. The different vent covers cured the problem.

I have a cyclone on my Endeavor. It does exactly what it's suppose to do. HOWEVER, in high winds it makes a lot of noise, whipping around constantly and keeping us awake at night.

On my two truck campers I used a "360 Siphon" which has no moving parts and they worked just as well. They're non directional so they work when the coach is moving or parked in a wind storm.

I'm going to remove the cyclone and replace it with one of these:

X 2 siphon 360 works great.

I've always heard that you should turn off the bathroom fan before flushing as this will pull air directly out of your black tank when the valve opens.
