Strong sewer odours

[Beachbum2]

Hi all,
Just wondering if anyone else has a strong sewer odour in the cabinet beside the pantry in their 5h wheel unit. Ours is a 2020 32RLTS and I can’t seem to figure out how the smell could even get in…it looks sealed up solid.

Hi. I have a 2017 Eagle Ht28.5 RSTS. My wife and I both smelled something also. I emptyed the basement, and removed the wall to check the piping going from the bathroom. No leak. Then during a weekend trip started to get a drip coming from where the sewer hose connection is encased in the spray foam. I dropped the underbelly and found the problem. Black tank has a hairline crack. There was a poop pyrmiad under the crack. Small but smelly. Insulation was wet. In prosses of doing repair. Hopefully not like mine.
Good Luck.

So far, ours has not had a problem, but if it ever leaks, I hope we're in Canada at the time, because "odour" sounds much more elegant than "odor". Probably doesn't smell half as bad.
