wilanddij, please forgive me..... pull what off and clean it?
The one-way vents under the sink (picture on previous page). If they don't vent properly the trap will empty allowing sewer gas to escape the system, and if they don't close properly, guess what happens. I think somebody else also mentioned this, but they didn't mention the silicone lube.

Just as a suppose. Take a look at the fresh water tank. Mine can smell after sitting for a couple of weeks. It drove me crazzy the first time. I found the fresh water fill & vent behind a drawer next to the kitchen sink. It comes through the wall and down into the fresh water tank. I have treated it with bleach and let it set for a while and flushed. I keep my fresh water tank filled even while using the water from the RV Park. This is on a 2002 37T Discovery. Might a new place to look

Thank you for your response. I bought a new vent just like the one in the picture and installed it (also using the white tape over the threads). That's why I was perplexed that I was still getting gas fumes from that vent when the tank had 'stuff' in it.

When I was able to dump the tanks, I cleaned both the black and grey tanks with our built-in sani-flush system and put the blue liquid inside.

Maybe I bought a bad vent. They are cheap so I might try another one.
