Septic tank odor during heavy rain
We're new to having a septic system. Ick! The only time we notice a difference from our city sewer system is during rain. Then odor seems to waft out through the toilet. Sickening.
Does this mean the septic system has a problem? We were told that it does not. Does it mean we have a cheap toilet? I don't know! Is there ANYTHING we can do about it?
I saw this charcoal trash odor filter and wondered if I hung it right behind the toilet if it would help any. But I know absolutely nothing about this topic, as you can see! Appreciate any thoughts or comments.
