I've posted a couple of different times about sewer gas in the house, and have gotten some great advice from many of you. Unfortunately, none of the suggestions solved my problem. I did, however, just discover that there is a 90 on the basement bathtub drain. No p trap. Problem solved?
I know, put a p trap on there and see if it solves the problem, right? Unfortunately, that means tearing out the whole bathroom so I can wreck out the concrete and make the "hole" deep enough to accommodate a p trap. There definitely isn't room for one as it is now. I think this may be where they went wrong in installing this bathroom; not digging deep enough to allow for a trap, using a 90 instead of doing it right.
Thoughts and suggestions appreciated!!
