Black Tank Smell Coming through Kitchen Cabinets

The black tank smell wafts up through the kitchen drawers and in around the stove in the kitchen, some even comes through heater vent in kitchen..some comes through the drawer in the bathroom...
We have installed a fan on the top black tank vent. blocked some pvc vent pipes under kitchen area. still have black tank smell wafting up in kitchen and bathroom cabinets, worse under kitchen cabinets.

Any help anyone?

Are you using septic treatment chemicals in both grey and black tanks?

You will get better replies from forum readers if you identify the rig you are inquiring about.

Wow! Joined in 2008 and this is the first post. That has got to be a record.
A very belated welcome to the FRF. I agree with NamUSMC on providing a clue however the stink you describe may be generating from the gray tank and coming in thru stuck vents which happen to be located exactly where your stink emanates. If your coach age is commensurate with your join date and seldom used, you can try to unstick the vents. Many methods available. Also, maybe some black tank treatment in your gray tank might ease the odoriferousness but if it does, you have not solved the problem. I hope my shot in the dark helps.

Did you block the check valve drain vents under the cabinets? You can't do that. Just make sure they are working. They need to allow air in order to drain. Where did you put this Fan? On the roof? Do your p-traps have water in them?

When mine sits for a time, the water in the P-traps evaporates and stinks up the place when I move. I have to remember to add some water before we leave again.

I also have an issue sometimes when I leave a rear vent open and have the air running. Some weird air vortex on the roof that sucks the black vent smell back into the coach. Have to remember to close that vent.

update on original post

Our RV is a 2003 29' Sunseeker LE. My wife wrote the original post. We didn't put a fan on the vent - it is actually a venturi based vane on top of the vent pipe. I have tried putting plastic bags held in place with a rubber band over the under sink vents but that didn't solve the problem.

Thanks for the replies so far - they have given me some things to look into. It is still winter weather here (snow tomorrow) so it may be awhile before I can look at things up on the roof. The vent plumbing is not very accessible. Does anyone know if the grey tank is hooked into the black tank vent?

On my wildcat 5er, they separate. I have 3 roof vet caps. close your roof vents and see it goes away. Use a tank treatment.

Gray tanks can have just as bad (sometimes worse) smell than black tanks. Fill your gray tank and add some bleach, this will help sanitize and kill odor causing bacteria in your tank. The same can be done with black tanks. I would also change the vent under the sink, this is most likely where most of your smell is coming from.

I had the same problem.

It turned out to be a damp dishrag that was placed on an inside door towel hanger that had somehow fallen and became lost behind some pots.

Time, moisture, and bacteria worked their magic to create an awful smell.

Might want to search for a "non-tank" odor source. Maybe something died in there over the winter.

Sometimes the simple answer is correct.

Don't rule out the smell could be from your grey tanks through the P traps that lost their gas seal when water evaporated. Those grey tanks can get rank smelling as everything in there gets ripe, sours and marinates... and can smell allot like you have a sewer black tank gas leak.
