Sweetfilters eliminate sewer vent stack odors overnight.

: I recently had a septic system installed, then a bathroom (toilet, sink, shower)and washer hooked up to it. The bathroom smells, the smell seems to be coming from the shower drain. A breather pipe is located just below the shower drain (between shower and septic), and a second breather was installed when the first did not seem to be working. The second is between all the fixtures and the septic line. Any ideas, assuming the septic tank is ok? (the septic people are coming out tomorrow to check the tank).Thanks!
