I'm not a RV expert and never said I was so I can only give my experience. So if I wasted my time and money to bad for me. I do know that the smell on a couple of occasions seemed to be caused by air pushed down the vent pipe and as the traps were all full and the toilet valve was closed and cleaned it made sense to me that it could be helpful to add the vents. I have had no issues so far.
Not to be to sensitive why the attitude with the replies. What ever just trying to help.

phil dont take it to heart .......
im just trying to save someone from loosing 65.00
no hard feelings man

true you may get a stink when opening the toilet becuase the air is drafting backwards .

the only TRUE way to somewhat vent your tank of fumes by adding fresh air is to have a reversible fantastic fan and turn it to suck air in not out then open toilet .

alot of people make the mistake of turning the fan on when doing number 2 and when they flush the fumes from the tank will be sucked into your camper while toilet gate is open !

sorry if I made you upset .

No problem I appreciate the response. I only got the smell when driving and it would last for 5 min. or an hour I figured the cyclones rotate to not allow air to pressurize the waste tank. Guess not. I don't want to hijack the thread I'll dig through the search and see what I find. I know there has been a lot written about the smells and causes.

The vent pipe is strictly for preventing the tanks from collapsing during the emptying process. The system is completely closed with only the vent pipe as an opening, just like a soda or milk jug. If you fill a milk jug with water and turn it upside down, it will collapse the jug. Same thing would happen if you didn't have a vent pipe on the holding tanks. Also consider the vent pipe is at least 8ft or more from the tank. Blowing across the top of an 8 foot pipe 2" in dia. will not pull air out of a tank that is sealed.

I use eco friendly product that I can't remember the name but was recommended by the service manager at our dealer. I flush the system at every dump and I think its about as clean as these things can be. I can't argue the effectiveness of these thinks. All the points that you all make are logical. I bought these at a RV show and the reason was again for a moving motorhome. If its a waste of money I did save the stock covers and will replace them when these need it.

I respectfully disagree with that statement....at least the word "strictly". When you flush water down the toilet, that should start a slight air pressure increase in the tank. Ideally, instead of that extra air blowing back up the toilet connection, it should start the air flow up the vent pipe, and keep that flow going until the toilet valve is closed, so no fumes enter the camper.

And what about tank heating during the day ?? With the pressure increase, if the vent wasn't there, then you open the toilet valve and all of those fumes blow back into the camper.

The vent pipe serves several purposes, not just 1.

You are correct mtnguy, I should have used "primarily" instead of "strictly". As far as wind or air blowing across the vent whether with the Cyclone or whatever kind of cover is just not possible on a closed system as explained before especially with 8'-9' of pipe. Just can't happen. Now, if you open the toilet, whole new ball game.
