Hello Capt Ron.
Did you get your black tank from army surplus or off e-bay?
All I have to drive is a bus,
Man, you da' man, driving a black tank!
Do you have pictures?
happy coaching!

Your vent line cannot be open (a cut in it) until it terminates at the roof. It will vent through any opening in it. How did u get a cut in a vent line? What do you have for material--soaker hose from WalMart? Tank odors will come up thru a dry trap on a washer standpipe and an empty trap on anything else. |

Aside from the odor leaking in through the crack in the vent line, sometimes wind against the vent while in motion forces the smell back up through the toilet. We put a PVC tee on ours aligned from front to back that draws the gases out while moving. |

Are you venting within coach?
Air pressure is greater where odor coming from to lower pressure areas (smells) while driving.
Remedy the problem either increase air (cabin) pressure via front inlet vent (not front driver side vent unless design to increase pressure). Or install outside vent toward rear of either side. You can bring odor back in from outside rear end due lower vacuum in cabin then otherwise.
If you go thru roof vent then add a tee so neutral air pressure is always equal or less then around vent system while standing..

Once again the marine industry can solve your problem.
GROCO is a long term marine mfg of hardware that has just copied a Euro solution for the US market.
Seems when the Swells line up their mega yachts , side by side on Cannes or Monti Carlo the stench from their neighbors holding tank would upset the guests.
Solution , pump a small bit of air into the waste tanks to change the bacteria from anerobic (no air) to some other kind.
IT WORKES!!
So GROCO has released a setup for US boaters.
This would be FAR better than dumping chemicals down the tank , as the chemicals are the cause of so many Free, State Welcome Center and roadside rest areas dump stations being closed Perminantly!
Should work for ya!

ff: sounds like another electrical appliance to run. Not arguing w/how effective it is since waste decomposition tanks do require a certain amount of oxygen; without it they will not work. However, a properly designed and installed system with natural venting will work just fine. One of the biggest mistakes is undersizing and insufficient vent lines. The mega tanks that many seem to gravitate to require more than a 1 1-1/2" vent line.
In CA. one of the biggest problems encountered and cited as justification for closing state maintained dump stations was and continues to be non-degradable waste (diapers and beer cans). There are only 3 or 4 left on the highway systems in CA. and I was surprised 3 yrs. ago when they re-built the rest area on I-5 in Willows and kept the dump station. |

"One of the biggest mistakes is undersizing and insufficient vent lines."
Agreed but some folks think a "saving" of the few cents between 1 1/2 and 2 inch plastic is a bigger deal than the interior stinking .
After all it only STINKS when you move with a window open.
2in works for my 54 Gal combined tank , Drivers Window open or not!
Perhaps the electric air pump could just operate say an hour before movement , and during the trip?.

if you have a r.v. toilet...sometimes the flap thingy at the bottom of the bowl doesn't seat & make a 'seal'...use silicone spray weekly in the flap... |

FF
Is this air just "ventilation" where air comes in and ventilates the air space of the black tank or does it actually have a bubbler, sort of like an aquarium to really ariate the black water?
I wonder how effective it might be to have strategically placed baffles that forces the black water to mix and arreate with the movement of the vehicle.
Hmm, thoughts to ponder

An RV waste holding tank is just that - A holding tank.
Adding baffles would make cleaning the tank more difficult and will result in it smelling worse for a longer period of time.
The aeration procedure is a bit more complicated than adding a bubbler or stuffing an air hose in there. Try to visualize as I did after reading your post, the vent pipe being obstructed while the air pump was doing it's job....

(" the vent pipe being obstructed while the air pump was doing it's job.... ")
Assuming the vent could become obstructed, unless the tanks sides are supported by wood or metal walls, could effect a premature failure of the tank, hope it was empty when the sides blew out!
Adding Baffles was a thought, one which I had second thoughts about after I re-read it.
Adding a bubbler, or two, would add more oxygen to the, err, waters than if it stood there with only a vent line.
I don't know what it would take to plug a good sized vent pipe, but I have seen some strange things cause failures on lines in the past.
I would presume the air pressure would be kept very low to prevent 'premature failure' of the hopefully empty tank.
Then again, I don't know much about aeration of the black tanks contents other than with every load dumped there is about 1/2 gal of water that dumps with it. that would be a watery mix of which aeration might work.
My interest was how it was done, and I am also curious WHY it works to control oder.
Most articles I have read suggested adding bacteria, like RidX for septic systems, to control solids and oder.
I still have an interest, but now less of a concern.

What's with the vent pipe being larger than 1.5" ?
I have yet to see a roof cap for anything larger than 1.5" pipe. It's only a vent, I have even seen bathroom sinks draining down the same pipes as the tanks are venting up without any problems. I wouldn't run a kitchen sink that way, but it might still be okay.
