I was called to a dental office to check their traps for sewer gas. Of course when I was there no smell. But after talking to the dentist he thought it was coming from the trap under the sink. Because at that sink they are cutting plaster they use a " Gleco trap system" to collect solids. Also after the trap and before it goes into the wall they have a under sink vent. Do you think eather of these two could cause a sulfur smell that is so bad they can smell it in the whole building and other times no problem.
