Used to have the same problem, even using the black tank flush system and the blue pods. Then some seasoned veteran told me to try running the flush until it ran fairly clean....then close the black tank valve with the flush water still on and allow the tank to fill for about 5 min (ours is a 40gal). I was amazed how much more "stuff" came out when I opened the valve. I've been using this process for nearly two years now and it's worked remarkably well in lessening the odor

Also use the clear elbow & rinse, rinse, rinse. Worth the time & effort.

Sounds like the secret is to rinse the crap outta it.

Be careful there. I have cleaned mine with bleach, when odor and bacteria got out of control, but it is dangerous. Urine contains Ammonia. Bleach contains Chlorine. Now I am not a chemist, so if I am not precisely accurate don't have a fit... MIX Chlorine and Ammonia and you get Chlorine GAS and Ammonia Gas. Both pretty much poison to people.

Toilet Odor

RVs without an outside black tank flush can use five gallon buckets to pour water through the toilet into the black tank. I suggest you pour at least three buckets through the system with the black tank valve open. This will effectively flush out the black tank. Pouring the water through the toilet rapidly gives the water a strong flow which takes accumulated solids out through the black tank outlet. Again, at least three buckets.

I agree with the last few posts too

Just draining the black tank does not clean the black tank. I flush thoroughly until the water runs clear. If I'm not going to be using the camper for a few days I'll add about 1/2 gallon of bleach and dilute that with 5 to 10 gallons of clean water. This keeps the tank from generating odor while sitting in hot weather.

I flushed my black tank this past week and filled my 45 gallon tote 4 times. Needless to say our seasonal CG doesn't have full hookups. But at least I know it's clean now. I also close the black dump valve during the back flush process to allow water to accumulate in the tank. You will be amazed at how much sludge comes out when doing that. I'll use the blue stuff with the the next 3 or 4 tank dumps and then flush again. Lots of work in this CG but no smell when dumping or flushing the toilet. YMMV!

Check the vent cap on the roof and try the GEO Method

The rotten egg smell comes from the water having bacteria in it I think I read somewhere. I would sanitize my fresh water system to see if that helps.

The trick i have found is get one of those toilet wands to clean inside of tank, dump 5 gal bucket of warm water in stool & fill your black tank w/water take a drive then dump. While dumping dump 10 -15 gal water down the toilet to flush crude that has broken loose this will also clean your sensors. Make sure dont dump unless your black tank is 2/3 full.Use plenty of water when flushing toilet water is your best friend when it comes to black tanks
