I've had a few moments like that mechanic must have had. "What tha? Would you look at that?"

Glad it's fixed! One of those unusual problems that can be so troublesome!

How to correct the foul smell from the bathroom toilet vent system

Amazing enough I had the same problem. I was able to get the drawings for the vent system for the holding tanks...what I found is if you take the vent cap off the vent line on the RV's roof you will probably find there is nothing to isolate the vent line and prevent the odor from flowing back into the RV. What I did is take the expanding insulating foam and sprayed it on the out side of the PVC pipe to seal off the air gap between the PVC Pipe and the RV roof structure. I reinstalled the vent cap and no longer do I have that smell. I contacted Forest River and they indicated this must had been missed during the manufacturing process...good luck.

I also removed the cap at the top of the vent tube. Used spray foam around the black vent tube that was moving freely around inside the wall. Poop smell gone forever. Thanks for the help. Before that the odor was in the bedroom and bathroom of 2014 3170ds.
