Sewer gas from basement fixtures
Hello all,
We have a basement (full) bathroom that is just slightly above grade (I suspect it wouldn't even be allowed under current code -- it is an old house). The bathroom is right next to the outgoing sewer line to our septic tank & the toilet often gurgles and sewer gas comes through (maybe even through the showet stall) when upstairs toilets or showers are used. I'm trying to find a way to eliminate these odors. I read about backflow valves, but I haven't run across anyone using one for this purpose. In our utility room I can see where the line from the downstairs bathroom runs into the main sewer line, so it is accessible. Would this work? Any other advice?
Thanks
Scott
