Black tank odor

[smsawle]

I traded my 5th wheel for a 2013 Palazzo. Love it after 2 weekends of use. After the first weekend, we drove about 50 miles with a quite full black tank before we dumped. It just about stunk us out it smelled so bad. This last weekend we dumped at the campground. It stunk of the black tank for about 10 miles of going down the highway before getting better. Do I have a problem that can be remedied?

Do a double dose and then flush the black tank. Also you might check to make sure that the toilet is closed all the way. They have a tendency to remain open a crack. Their should be water in the bowl just like home.

You may want to check out installing something like in the above link. There are several varieties that create a negative pressure on your vent line to suck out the odors before they get too overwhelming. A gentle breeze over the vent line is all that is required to make them function very well. They are cheap and easy to install. I use one on the black as well as the gray vent and I seldom have a need for any chemicals to control the odor.

Thanks for the quick reply. We have always used the Bio method as our treatment. Will get some of this on the way to us. The bowel does retain water,

I also installed the Camco vents and it fixed my problem immediately.

Use the Happy Camper Extreme treatment according to their instructions, then after the tank is clean go to the regular Happy Camper treatment. It works great and we have never had any odor!

We used to use Happy Camper and it is pretty good. We replaced it with Pine Power. Not Pine-sol (sp) but Pine Power. It actually has pine oil in it, whereas Pine-sol does not. We put a pint in the black tank and it takes care of the odor and cleans also. We used to get it at Dollar General, however, they have stopped handling it, so it is harder to find. In a pinch, we go back to Happy Camper.

edit: The venturi mentioned above also helps and be sure to check the vacume break valves under the sinks. sometimes the grey tank odor can be almost as bad as the black tank. A defective valve will let the grey tank odor come in under the sinks.

We had the problem of driving and when it was flushed there was an odor, and I installed a 360 siphon vent tube cover and problem went away. Could also help if you put one on your grey vent. My mh only required one. Very easy to put on by yourself.

I used to use Pine Power but since Dollar General quit carrying it, it is hard to find anymore. So I changed to Happy Camper and wow! That stuff really works great, never a smell even in the hottest Southern heat. First you need to eliminate any issue such as blocked vent to the roof (wasps and dirt daubers love to clog the vent), check your AAV valves under the sink, make sure the smell is strictly from the toilet area and not somewhere else; then flush and flush again. Run about 2 minutes worth of water in the black tank and add Happy Camper.

Another vote for the Cyclone 360 vent and the GEO Method (search it on this site). Have not had any more odors, even while driving thru Texas in over 100 degree heat!

Household bleach. Cheap & can be purchased anywhere unlike "Happy Campers".

Plus flush it like crazy at dump. We flush 4 to 5 times per dump.

Just google 360 siphon and it will come up. I had a camco cyclone and it only works when there's enough wind to draw odors out because it works like a wind vane. The 360 works with little to no wind. It sells for $30. I ordered two and only needed one, and would be willing to sell for $25 plus shipping from 73505 (new and in original package, black in color).

I just had the 360 Siphon vents installed on my motorhome. Have not had an opportunity to use it yet, but I have heard very good things.
