Black Water Tank Bad Oder 2022RB

I will experiment with it.

I ordered the Camco vent. I am going to fill the tank with fresh water at the dump station where I am camping now and drive it home and dump it again.
Thanks

How is your toilet seal? Will it hold water? If not that may be your problem - I know it is new but maybe it was installed improperly.

I recently had the same problem and it seems it was caused by a blocked vent pipe to the black tank. There war a nasty odor when flushing. I believe that was the result of overfilling the tank. I solved the problem by letting the black tank get fairly full then adding water to the vent pipe from the roof then opening the tank valve. The resulting suction form the escaping tank contents cleared the vent.

I noticed the same thing on our 2021 2500RL. Our last trailer didn't have that problem. A lot of good hints from others on what to look for.

I have a new 2022, 2600RB. I have owned 5 other trailers and I know how to dump, clean a black water tank. For some reason this is a stinky set up on my trailer. I am referring to boondocking (not Oder eminating from a hook up).
We have doubled the amount emzyne treatment, but its still pretty rotten with very low levels of black water (I don't trust any of the my gauges BTW).
My previous trailer, a cheap Hideout had a vent pipe off black water tank and my others might have also. None of them had this issue and we haven't had a recent change in diet.
Any thoughts on this issue would be greatly appreciated. Humorous replies are OK also.
Thanks

Looks like you have received good advice. FYI... we always have a hose connected to our flush connection, and flush after each dump. (Dump when it burps...1/2 to 2/3 full.) Then put maybe 5+ gal in to prep for the next dump. Also we use 3gal. Of cheap vinegar in our empty black tank to slosh around when we have been in a place long term.
Seems to really clean it out.

You must have an AAV under the bath and kitchen sinks. If it was not installed the p trap water will get sucked out and the tank smell will come up the drain. Also the other comments should be very helpful. By the way we had a 2019 2600RB and out grew it. It’s a very nice couples trailer.

Toilet seal is good.
I think that I have found some solutions to the problem thanks to you and others on this forum.
