Grey tank can stink just as bad as the black. If you never use your tub/shower the trap can go dry and allow fumes into the living space. Pour some water in your traps.

1. bad AAV
2. toilet not holding water after flush
3. sink or shower trap empty
4. bad seal between toilet and floor
5. blocked/dropped holding tank vent

(Over the past 10 years, I have personally had all except #2, pun, pun, and #3)

Be sure to check these for the gray tank too. It smells just as bad as the black tank.

If the plumbing system is working as designed, no "deodorizers" are needed. No plumbing smells will get into the RV (except when you open the toilet's seal to flush it with the exhaust fan running). If the plumbing system is NOT working as designed, no "deodorizers" will work.

What is an "AAV"?

I had something similar once and it finally went away after I filled the tank completely with water and chemicals and let it sit for a week. I figured something got stuck to the side of the tank.

We have been using Aqua-Kem Deodorant blue cap bottles for 20 years or more. We flush with regular toilet paper and turn on the fan as needed. If it's hot outside we don't go chintzy adding extra bottles to the tank.So far no problems.

Sometimes I need a reminder why I went the hideously expensive marine toilet route. Other than avoiding having my knees jab me in the chin this thread is an excellent reminder. May I wish you the best of luck solving your problem...

An Air Admittance Valve is necessary under the cabinet holding a sink unless that sink's drain line is connected to the roof vent. Without some kind of air admittance vent, the suction of the water going down the drain would pull all of the water out of the sink's trap, allowing sewer odors to come up. The AAV breaks that suction. It is a one way valve, allowing air to go into the drain line, but not allowing air (odors) to come back out. If the AAV fails open, it allows air (odors) to come out. If the AAV fails closed, it sucks the water out of the sink's trap allowing air (odors) to come out. The solution for either condition is to replace the AAV. It is cheap and easy. It costs less than $10 at a big box hardware store, and just screws on.

The only time the grey / black tanks should be completely empty is when you winterize, otherwise never. Once you've dumped & flushed either you want to add a minimum 10% capacity of the tank with fresh water and tank chem of your preference which you'll then start your next camping trip with.
