We have two sinks in our master bath. A rotten egg smell emits from one of these sinks only when the water runs down the drain. Any idea what is causing this?

Check to see if the offending sink has an overflow hole near the top of the rim. If so, put the stopper into the sink and pour in one cup of bleach. Slowly (so as not to splash the bleach) fill the sink with water and let it run down through the overflow. Keep running water until the bleach smell is gone. Many times the overflow has bacteria that form in the "runway" for the overflow. This operation should kill it. Good luck.
