I need help finding the source of a "sewer gas" smell; it seems to come from both sinks in my master bath. The sinks, water supply and drain were replaced in September, 2013, as part of a gut/remodel project. We didn't notice the odor until about February, so I don't think plumbing was improperly installed. I don't see any kind of gunk in the drain. The smell seems to come and go and is not over-powering, but a little goes a long way with that smell! The sinks are not on the same wall. We haven't inspected the plumbing vents yet because we don't want to go on the roof unless absolutely necessary. Please help!
