Sewer vent smell - need advice
I am having an issue with sewer odors in my trailer. They seem the strongest around the toilet. I've done some research on here and I think I've narrowed it down to the rooftop vent for the black tank...

Stick a steel measuring tope down the vent. Unless their is a bend it should go to the bottom of the tank. Take a measurement. When pulling the tape out you should be able to catch the bottom of the vent pipe. That will give you another measurement. From there you will know if the pipe is on or close to bottom of tank. If not on bottom it should be sealed at top of tank, try to gently turn or lift up.it should not move. If it doesn't move I'd add a coupling or 360 vent. If it moves....go get a beer it's going to be a long day.
