I have a shower drain in a new house that's consistently admitting sewer gas two days after its last use. We have 50% humidity, no heating or a/c running, and none of the other drains are doing this, including two guest baths that go weeks without having water run through them. The shower is on the ground floor, and there are stacks to upstairs bathrooms both up and downstream of this fixture.
Before taking this to the builder (new home warranty), is there anything I can do to help define the problem so I know they're correctly addressing it? The house is slab on grade, so I can't visually examine the shower drain. My test so far has been to run the shower, then check the bathroom periodically until I smell sewer gas.
