I am having an issue with my downstairs and one of my upstairs toilets when flushing. I am getting a sewer odor. My toilet in our master does NOT have the problem though. I first thought I had a venting issue, so I climbed on roof and ran house down my vents (2 of them). That did seem to help a litte bit.
I am also wondering if my toilets aren't sealed good (wax rings) if that would cause this?
Would a bad seal on one toilet cause two of them to smell though??
I assume those two toilets are on one vent, and one my master is on the other.
I do have a septic system which I just recently pumped as well.
Any thoughts/suggestions would be appreciated.
