Trouble with Black Tank
We just purchased a 2006 Jay Flight. Apparently the previous owner was nice enough to store it all winter and than sell it with the Black tank full!! When we connected up at the site and went to empty it -well it seemed like it was emptying but the check system is stating the tank is still full. At first we thought a piece of toilet paper maybe blocking a sensor. OK no biggie. So someone used the restroom and when they flushed there was no hiding what they had done!! OMG the whole trailer stunk so bad!! We rechecked everything and we have no clue what or why the system is doing this. If you look down the hole in the toilet you can see the bottom of the tank, it's empty. We just don't know where the smell is coming from. Any suggestion?? Please help!!!!

Trouble with Black Tank
Just fill up the tank with fresh water and dump it. Repeat once or twice. That should take care of it hopefully.

The black tank sensors are a problem in most rigs. Mine reads full all the time. You did the right thing. Look down the toilet.

Awesome parting gift by the PO! Its possible that the sewer hookup at the CG is venting through the hose to your black tank. This would be expecially true of the valve was left open for a long period of time and in your dump hose is perfectly straight at a downward angle to the sewer. dump in some pine-sol/cleaner etc into the tank with plenty of water and let it sit for awhile then dump.

Black and gray water sensors never work right ... if your toilet is a straight drop you can just look down and see how full it is.. and if you have water in the shower stall you know it is time to drain the gray...

Check the vent on the roof for blockage.

Look under the sink in the bathroom, you will notice that there is a small vent cap behind the p-trap. The problem is when you close the bathroom door the air is also sucked out of that small vent... hence you odor. I taped the vent hole closed and make sure I have a window open when using the ceiling exhaust vent...

The tank sensors are useless... although when you hold the sensor monitor switch down for about 10 seconds, I get a better reading.

Usually these caps are designed to only allow air flow in one direction anyway (pull air in) taping this off may cause your other drains such as your sink or shower to not drain properly. I am going to guess that since the Previous owner didn't properly clean the tank out he left you with a really nasty mess that really just needs a good flushing with a lot of water! Our new TT was equipped with the flush system on the black tank, which is a life saver! In your case, you. May want to consider making ( or buying ) a wand to actually put through the toilet and help flush that ****er out really good! Also our neighbor recently bought a new sewer hose hook up that has a hose attachment that jets water into the tank to help flush it, he said it worked pretty well ! Also buy some of those handy blue deodorizer packs to drop in your tank, hey can be a nose saver!! Good luck!

You can try and scub the sensor clean with Ice cubes and water dump a few big bags of ice down the toilet and fill with water and then take a drive with lots of turns and then dump,it might help or not......if anything it will clean the tank and should help with the smell.

Is your Jay Flight equipped with a Turbo Maxx, Fantastic or similar high-volume fan installed in your bathroom vent? These types of fans can move large volumes of air, similar to what an attic fan does in a home. If the fan's running in exhaust mode and your bathroom door is closed, it can restrict the airflow and create a slight vacuum in your bathroom. An RV toilet has no built-in trap like your home toilet, just a pipe that runs directly into your holding tank and, if the bathroom door is closed when you flush, it will allow air to be drawn down the black tank's vent stack, through the tank and up through the toilet carrying those gross odors you describe with it. To make matters worse, RV bathrooms are so small that it doesn't much to make it smell like you took a dump for three people.
The solution: Open the bathroom door before you flush or momentarily turn off or change the direction of the fan so that it draws in air (which will slightly pressurize the bathroom when the door's closed and push air down through the toilet when flushed, thus keeping the tank odors at bay).
Also, I agree with the previous poster that you shouldn't block the internal vent (if so equipped) on your plumbing. These do contain a one-way valve that only allows air to be drawn in, never out. If you ever detect odors coming from your internal vent, it's defective and should be replaced.
And as a final note, don't even bother looking at the gray/black tank level indicators. They're notoriously inaccurate after you use the tanks the first time. The only ones that seem reliable are the See-Level brand and they cost $$$ to buy and install. You usually only see these as standard equipment on high-end RV models. Get to "know" your tank capacities and monitor them yourself. I "know" my black tank will go for a week under normal conditions (just the DW and I) and I simply empty the gray on a daily basis. However, I "know" I can squeeze two days of use out of it if we practice water management when we're at a site with no sewer hookup. In time, you will learn this technique.

Trouble with Black Tank
I have a friend that swears by Rid-X, the stuff made for septic tanks. He just puts it in on the way to the campground with a couple gallons of water to slosh it around. He says it keeps the prove clean and cuts down in the smell.
Sorry to hear about the unexpected gift.

Oh how much I hate my iPhone autocorrect.
What I meant to say was the Rid-X keeps the probe clean and cuts down on the smell.

Trouble with Black Tank
If you want to get rid of ALL sewer and gray tank smells? Put a siphon 360 on your black and gray tank vents and all smells are gone. I put them on mine in the spring when i had the roof replaced, all i can say is they work no more smell on hot summer days at all.
