What is my bathroom sink smell?
Every morning a foul smell emanates from my bathroom sink drain. It does subside once the water has been running and gone down the drain. I have taken the plumbing apart and cleaned it thoroughly, I put odor sticks down the drain every month, have used baking soda+vinegar, drano but nothing helps. Have had a plumber, contractor and the water department look at it, but no one can figure it out. The plumber says just to close the drain, put water in the sink, then let it drain out, which does work. It is only in the upstairs bathroom sink, but no in any other sink/shower/tub. Does anyone have any idea of what it could be? Thanks.
