Sewer Smell In Motion

[MotoWood]

It seems that when in motion with the black/gray tanks more than 1/3 full, we get a pretty bad smell inside. All the drains are closed, etc, and I can't figure out where it is coming from. One theory I have is that it may be from the washer/dryer unit, which may or may not have a P-trap in its drain, but I haven't figure out a way to test it. Has anyone else had this issue?

at the top of the page.)

Besides cracking open the vent a bit, I installed one of these which really helped.

Too funny - I actually started my search w/Google and then figured I'd search the Berkshire forum directly, to no avail. You found good stuff in 2 seconds! Such is life sometimes.

Great info, everyone. I still suspect the W/D as the entry point, so the negative pressure caps should help. Thanks.

I agree with AMXPRESS,
I installed the cyclone sewer vent and it eliminates all of the smell while traveling. It also works great while camping since the vent rotates with the direction of the wind and seems to eliminate the smell even while camped. One must remove the old sewer vent cap and reseal the cyclone vent with a ton of Dycor lap sealantl, but really only takes about 20 minutes to install.

I own a Solera and it happens to me. I solve the problem just by making sure there is always a little water left in the toilet bowl.

After flushing, about an inch of water should stay in the bowl, it acts like a P-Trap.

If water does not stay, you may have something caught in your seal like a piece of toilet paper or beurk...something else. Put a latex glove and feel the seal. Even a very small thing will make the water goes away and the smell to get out of the tank.

I do not recommend using a toilet brush to clean the seal. It may make things worse by scratching the rubber.

Good luck.

I had 3 installed on my TT and I can see where they will work perfectly for hauling out the fumes. Last week they were spinning like a windmill on the roof parked in the yard.

Here is a link to another Forum talking about that seal problem. Good reading.
