We recently bought a house and my kitchen has sewer gas odor. Under the sink I saw this vent was screwed into an adapter and then slipped into another pipe. Male had threads, female did not. It was loose so I figured gas was escaping from there. I removed the adapter piece and bought another piece with threads to attach to vent and a slip to slide into the piece below. It was a bit loose, but the man at lowes said there wasn't an in between size. I took plumbing adhesive and filled the gap. It's been two days and I still smell sewer gas. What can I do to fix this? And can I just seal it off?
