Two things happened the other day:
1) huge rainstorm
2) my main vent pipe in the house was stuffed with a rag by a construction crew in the attic.
And I guess a third thing, the basement shower started to leak sewer gas. I put a wet rag over the drain and the smell went away. The toilet and lav in the bathroom are fine.
I'm guessing something is siphoning the trap. But I believe this group is vented from a second 2" vent that also vents our kitchen sinks. I don't really know. The guy who put this bath in was not a plumber.
Should I snake the drain? I uncapped the main vent and ran some more water in it to fill the trap. We'll see if that helps. It seems to have stopped the major smell, but the trap always smells a bit funky.
Any ideas? I suppose it's possible this bathroom has no vent at all, but I believe it hooks into the vent for the kitchen group. Certainly it has no separate vent of its own.
