Trust me when I say that I'm NOT going to try to find out, Becky!

aage...

pooring water DOWN the vent tube is the simplest way to check for PLUGGING...

one SHOULD be able to smell some tank aroma AT the vent outlet normally.

if PARTIALLY plugged odors will still pass UP and water down.

IF totally plugged the water will either soften the plug OR evaporate.

unless the plugging is something ODD like sticks and stones and animal parts.

those things require other techniques to remove.
__________

using the flush king to force water UP AND OUT the vent tube is UNwise.

in g's case it was accidental,

and it is FORTUNATE something IN the tank didn't block this flow.

because it is VERY POSSIBLE to blow the toilet gasket or bowl seal OR break a retention bolt...

by pressurizing the tank with a flush king.

and those are the EASY things to fix.

one can also RUPTURE the connection of vent tube TO tank or drain values FROM tank...

these are much hard things to fix and all of these leaks are messy.

IF the vent tube is blocked AND the toilet bowl closed

air pressure OR water pressure from the FK may break things, don't intentionally try that.

everyting about the tank and drain and waste plumbing side is LOW PRESSURE sealed only...

cheers

How about filling the black tank 1/2 way with fresh water...
add 1/2 a bottle of dishwashing soap...
then tow down the road sloshing the mess...
while a chase vehicle watches for bubbles coming from the roof vent...

I like the half bottle of detergent approach if only because someone could make a video of the bubbling out the vent and post it.

Another approach could be to use a steamer (another of my suggestions I wouldn't try). And, Becky, yes, you can get a fountain out the vent and a waterfall down the side. I had flushed the tank pretty well before this happened, so it wasn't a situation where there was toilet paper and worse stuck to the trailer. The water was clear. It's best to laugh about it and hope no one saw it.

In post 13, Aage, you say "my only complaint is that there is frequently a 'disharmonious' scent present." One problem could be the deodorizer. They are not all the same and (unfortunately) we find the greenest ones last the least time, or sometimes we smell odor for a short time and then it goes away. One time it sometimes happens is when we stop after traveling for a while—obviously it shakes things up and they have to calm down. Then we don't have the odor until maybe the next day's travels. It usually means we will have to backflush the tank soon. Turning on the bathroom vent fan helps as a temporary solution.

You may not be getting the tank clean enough and that's why the occasional odor. There are a variety of ways to flush—the wand down the toilet, the integral Airstream system are two. I think the Flush King works well because you can see what's coming out. It is tedious because it can take quite a while and you can fill the vent. It's impossible to know just how full the tank is when you backflush and whether you have gotten everything off the walls. If there's stuff stuck to the walls and the water level is below that, some odor is inevitable. You can use the ice cube method to scour the tank, though we believe ice cubes go best with gin. Also we have found putting 5 gallons of water with the deodorizer after we have flushed the tank helps most in preventing odor. We find we have to flush the tank after around 6 to 8 days.

If the odor is only occasional, maybe there's no blockage. I don't know, but it would seem to me that a blockage would cause a constant odor.

And, finally, I was ready to squash that bug too.
