Sulfur smell

Hi folks, need your thoughts on the sulfur smell in the hot water from the bathroom sink only. I drained the hot water tank and no smell there, just at the hot water faucet in the bath sink, stinks! The so called stainless sink in the bath was showing rust and the dealer replaced it. It has smelled ever since, not the sink but the hot water!
Thanks in advance

    Usually that smell comes from getting some pink into the hot water tank, then heating the tank up. However... the smell should be in all hot water, not just the bathroom sink.

    Anode rods in the water heater are notorious for causing the sulphur or rotten egg odor. But that would not explain the bathroom sink only with the odor.

    Our sulfur smell was one of the starting batteries that went bad. And of course it was the back one, you had to pull the front one to see that the second battery was bad.

    Check the air admittance valve, usually located under the vanity top. Might have been damaged when sink replaced.

    We had the same smell. Flushed the hot water heater and changed the anode. Problem gone.

    I call it an internal vent but that could be a possibility.

    I discovered a sulfur smell in my bathroom sink was from water in the lines running to the washing machine, which I don’t have. I flushed the two lines and the smell was gone.

    amxpress just beat me to the punch:) I had the same stinky problem with my new at the time 2012 5er that I could not figure out and somebody told me to hook up a hose to my Washer hot and cold lines and run them outside or in a bucket whatever to get the stale water out of those lines since I do not have a Washer in my rig either and that did the trick

    Atwood tanks can produce that smell from a reaction of hard water and the aluminum tank and being stagnant. Tried bleach flush and that didn't work for long. Read the manual and Atwood says to use vinegar. Worked well for 5 years so far.
