Why is the water from only one bathroom sink smell awful?

This only happens when you first turn either the hot or cold water on, or both, and after you run the water for a little, it clears up. How can I fix this?

    It happens in my bathroom sink also , but not in any other faucet in the house. I Think it is in the old water line , and it is the least faucet used .. so it sit in there and starts to smell of sulfur . JMO ..

    Try pouring peroxide down the overflow hole, do this with the sink stopper pushed down. I also sprayed bathroom cleaner in the hole. I had gunk growing in the overflow. Never knew this could happen but it did.
    Good luck and I hope this helps.

    What is the source of your water - city, well, cistern?

    It might be the pipe. Try putting baking soda down the drain and then wash it down with vinegar.

    I had that problem and even had roto rooter to check it out thinking it was a sewer problem. I finally found if the sink is not used often the water in the p=trap stagnates. That's why after you run the tap a little the odor goes away. I make a habit of putting a little bleach in the sink every day or so. I have 2 baths so they may not get used every day.

  • See if any of these links help. Could be a number of things - and hopefully other Hometalkers will have suggestions too.

    what are your pipes made of, maybe steel. Sounds like corrosion

    I have the problem in one bathroom, too. In the shower. But only after heavy spring rains. It drains to a septic. I pour pine cleaner ot any scented cleaner I have down the drain and it clears up. If yours is the spigot you probably need a new pipe. Just guessing, here. Sorry

    is it coming from the drain? Clean out the drain. From below the sink, in the drain you'll see the plug attached to drain. you can unscrew that and pull out the bar that holds the plug up. Just remember how it was attached so you can put it back togethe. Hair and products get caught on this bar and makes a horrible stink.

    Besides putting some cleaner down the overflow hole you might want to try cleaning it out - you can get a wire tool with a velcro type attachment at the end (to pull out hairs, etc.) for a few dollars. If it is really plugged up (I cleaned one out that was full of what can only be described as 'gross') perhaps with soap scum, old toothpaste, or other products that might have floated into the overflow - best bet is to take the sink apart and clean the overflow thoroughly. Or try stuffing the end of a page 60cc syringe in the overflow and using pressure try and move the blockage. Good luck.
